EF ECOFLOW DELTA Pro Portable Home Battery, Expandable Portable Power Station, 3.6kWh-25kWh, Huge 3600W AC Output, Solar Generator For Home Backup, Travel, Outdoor Camping
Generator worked as advertised. I love everything about it. I lost power at home and was able to plug in 2 refrigerators and other important items so I could operate close to normal during the 12+ hour power outage. I ordered another generator and now I’m waiting for the batteries to arrive so I can have a whole home back up system in case this happens again.
This was a pricy purchase. I still evaluating whether it was a good purchase for me. So far I’ve charged it up and use it to power small appliances. I noticed it didn’t want to charge on som of my home outlets. I also hate the placement of the telescoping handle to roll it. The handle would be easier to use if it was on top of the device, like luggage handles. Reaching all the way ti the floor is taxing for me. I’m disabled and I find it difficult to use and roll. I like the okone app. I plan on having a electrician connect it to my homes breaker box for back up power. I saw someone explain the use 2 as back up for their mountain cabin. I have solar panels so if I lose power at night I’m hoping I’ll have power during the night. My solar panels should recharge the device during the day.
Hurricanes are always a threat where I live. I’m not a fan of gas generators because of the noise, exhaust and the craziness at the pumps whenever a storm is approaching. After a lot of research I finally settled on this. I was impressed by the 3600W of power which runs all my lights and fans, my refrigerator, microwave and pretty much every 120V device I own. Then there is the KWh rating which tells you how long this unit runs them for. To put it in perspective this can run my side by side refrigerator for about a day. And yes, food is way to expensive to just sit and watch those go bad.
After getting this I realized how nice it would be to run my 240V range when the grid goes out so I got a second one and paired them with the Ecoflow double voltage hub. So now I have twice the power and twice the runtime. So technically I can now also run my water heater and HVAC with a soft start.
There are other brands out there and you can always put together a DIY but I was impressed by how smart and portable this thing is. Then there is the fast charge, the solar input, the Lipo4 batteries which offers well over a decade of service. Too many features to mention.
I’m not trying to sound like a show off but there is something about being able to just flip the light switches anywhere in your house when the rest of the community is it darkness. Makes you feel like you did your family proud. I also ordered the smart panel so even without power cuts I will be able to charge this unit off peak and feed of the battery on peak. This is one of the best purchases I’ve made this year. Whether is natural disaster, business or recreation now I feel prepared.
Nice and compact but heavy so good to have the wheels. Charged it with re solar panels and it works great so far. Got the wrong switchover panel that was included and am returning to get right one but have high hopes for the generator. Seems well thought out and solidly built. Easyto connect to internet with the App.
The EcoFlow Delta Pro was exactly what I was looking for! I didn’t want to mess around with figuring out inverters, uninteruptible power supplies, and how to make a solar power generator with backup battery solution play nice with my home electrical circuits (though the Deta Pro can be used for that); rather I was looking for an off-the-grid, plug-and-play battery solution that I can charge during the day using solar panels in my backyard and then use that power at night to charge my plug-in electric hybrid car. That is one of the niches for the Delta Pro. I received the Delta Pro within a few days of ordering it; it was easy to figure out and worked immediately upon unboxing; and when I realized that one of the accessories was missing, EcoFlow immediately shipped me a replacement. Five stars!
It’s a heavy unit, like any this size. Nice it has two handles and wheels for moving. Outlets gauges and controls up front. Has an on/0
Off button for turnnng ac on and off; would rather have a covered switch. Lots of different types of charging and powering options built in.
The perfect alternative to a gas generator for backup power during a storm. Used in connection with the transfer switch, it is very easy to operate. Battery life and value for the money is a subjective issue depending on what you want to back up. For me, it is well worth the peace of mind to know that when the power goes out for a day or two, I will still be able to run my refrigerator, be able to watch TV, operate the house fans, have lights and so on. You can probably get a gas generator for under $1000 to do some of that, or get this battery and transfer switch for between 3 and 4 thousand dollars. No longer do I need to have cables running all over the house to the gas generator, have to maintain the generator in the rain to have power, to say nothing about the noise and the smell of it.
Depending on what you are running, it will only last you a a day or two without needing to be re-charged, but most power outages do not lost longer than that. You can also get a solar charger for the system, which I have not tried yet. You can also get expanded batteries to give you expanded backup time.
Check out the You Tube videos that are put out by EcoFlow on the use of the battery and specifically the installation of the transfer switch; they is very informative, and worth the viewing time.
Easy to plug in to charge. Used to keep the fridge going during blackouts (for ~24 hrs). Has multiple USB charging ports as well as multiple outlets. Kind of heavy, so it may be hard to lift and carry but has wheels that facilitate transport. Overall good product to have as backup if your areas are prone to losing power.
I have a background in electronics and have built battery packs before. The level of expertise you get with this system is amazing. If you were to price out the components included with this unit and build it yourself, you’d be hard pressed to beat this price/performance. So what do you get? 1. A 3600Wh LiFePO4 battery. 2. A quality 3600W DC to AC inverter. 3. An 1800W AC to DC battery charger. 4. A 1600W MPPT charge controller. 5. Full array of the latest USB, DC and AC outputs.
I could write a book but instead of listing all the good, I’ll focus on what I’d improve.
1. Higher direct DC output. 30A is ok but to replace RV batteries without wasting power with AC conversion, a high amperage 100A + direct DC output would be great. 2. More Solar inputs. 1600W (150V 15A max) is good but makes panel selection more difficult. I’d like to see a multiple input MPPT to make it easier to maximize the solar input. 3. Fan noise. When charging over 900W or so the fan noise is very noticeable. (The Delta 2 Max can charge at 1000W and is nearly silent)
So, for the endless list of good this thing does, these are my wishes to Ecoflow for further development.
We can address the 100 lb elephant in the room. This thing is heavy. For what you get, they have done an excellent job making it portable though. The handles and wheels work great. If you want a more manageable system with nearly the same capability, the Delta 2 or Delta 2 Max and extra battery are a good option.
Full disclosure, I bought this unit with my own money. Ecoflow did ask me to write a review for a small compensation. (This did not influence my review as I was going to post one anyway.)
I had to return my original Delta Pro due to a RIP error code. The return and refund was smooth after I contacted the seller through Amazon. I loved my Delta Pro until it died. I loved it so much, I will give it a 2nd try.
I’ve had my Eco Flow Delta Pro 2 now and am so far happy with it. Our intent is to use this along with a few 100W solar panels during hurricane outages to keep our refrigerator and a few other items running. We haven’t had an outage yet thankfully, but have been using it to power our entertainment center, and anything that charges via USB just to get an idea of how it works and get used to it. The EcoFlow App seems to manage most aspects of the device that I would need to.
Comes in handy during power outages. Had one that lasted 24hr and was able to keep the fridge on and food from goiing bad, didn’t need to get dry ice which the stores already ran out of. Planning to expand the system with extra banks or maybe solar when they go on sale again. Shout out to 8-bit guy.
I spend a lot of time RVing (30 amp) on Skyline Drive and The Blue Ridge Parkway, so electrical hookups are not available. Skyline Drive has very short generator hours, so being able to use this during non generator hours makes life a lot easier. Recharging is quick, so it can be charged back up during the hours generators are allowed.
I do have two minor suggestions.
1. There is a tiny white light on the front of the panel that slowly fades in and out when in use. (i.e. charging phone overnight). The only way to negate this was to cover the light. “Dark Mode” would be nice.
2. A longer AC power cord. RV outlets aren’t in the most convenient locations, so an extra long cord would be helpful so that I don’t have to lift the (99 lb) power station onto a table to reach the outlet. (or use an extension cord).
The handle that slides out broke the first time it was pulled out. Refused to lock and then didn’t go all the way back in. The unit is awkward to move even with the handle locking which in my case I have to imagine but the weight distribution made it difficult to work with. The information about the unit when I purchased it didn’t specify how careful you had to be with not getting it wet. The documentation makes me worry about using it camping. I live in Florida and it stated to not use it in a humid environment. Clean with a dry cloth. The APP looks relatively good. I’m waiting to experience more use but looks like a decent program. The program uploaded and connected easily.
Have not been able to get this set up due to met helper being tied up on other Jos.
Shipping was prompt and this seems to be well built and I am very anxious to get it going.
This was easy to charge with the four part solar panel. Have had it for a year and just used it during a 9 hour power outage. Worked great, kept our refrigerator humming and after 9 hours, still had 80% battery left. Just wish they would actually list all household appliances that work with it. Don’t think we can use our range/oven with it, but can’t find any info about it and there is no manufacturer contact info in the owner’s manual or on their website. Also in fine print it says to deplete battery to 30% every 3 months and then recharge to at least 60% if not using regularly.
Update: 09/28/23: Ecoflow has made an effort to make things right for me, so I am increasing my rating. My initial issue caught them on a bad week I guess (it was around Prime Day) and their response then was not great. But since that time they have been responsive, swapping out the unit that didn’t work. I also returned a second Delta Pro that had a similar issue to the first. Two units were fried when I connected THEIR solar panels. So now I am a little hesitant to connect them again. Other than that I like the Delta Pro. I even ordered the extra battery so that I can have even more capacity. So not perfect, but no longer terrible either.
Delta Pro was great for 9 months. Then I purchased their 400w solar panel and it fried my Delta Pro. Now I can’t seem to get a response from customer service on how they will fix this warranty issue. They need to reduce the marketing budget and increase the support budget.
When you spend this much money on a product, you are also purchasing the customer service. That part of the product is poor and would cause me to NOT recommend any of their products
Oups le cble de connexion est bien prsent mais sous une trape que je n’avais pas vu ! J’ai donc d’abord cru qu’il n’tait pas livr mais tord.
La trape se trouve au dessus de la batterir.
Used it at home for a back up until the weather was good enough to use it up at our mountain property, got it with the 400 watt solar panel, first thing I used on it was a 1600 watt microwave for some spagettios, no sweat, then plugged a projector and a ps5 and watched a movie, as well as charged our 4 phones all at the same time and only used about 20 percent t of the battery, I then hooked up the solar panel the next day and it charged it up to 100 in 3 hours. Then used the ps5 and projector for 3 hours and microwaved some more food all in that frame to only drop to 75 percent, then later that day I played another 3 hours and it dropped to only 60 percent. Absolutely strongly recommended! Runs air conditioning really well too! Ran my ac unit that at peak will use 900 watts, but ran it overnight all night and had 27 percent battery after that.
Edit: My unit recently had an issue with connected batteries. It stopped “seeing” them and had to be warranty repaired. This does not change my recommendation for the device. However, I will say that you should keep your packaging. I ended up having to pay to have this packaged for safe shipment. That said, once I was finally able to get it shipped the warranty repair took only two days before it was reshipped to me. Also, be aware that the company doesn’t issue loners or cover down time in any way, so if you are using this to backup a mission critical application you may want to look at other options. This works great for what it is, but if it fails it’s going to be down for as long as it takes them to fix it, even if you may desperately need backup during that time.
Original review:
My initial take on this is that it is a very well made piece of equipment. The related android app is also steller. I currently have it integrated with a smart home panel and at the touch of a button, or an unexpected power outage, this takes over one or all of the 110 volt circuits in my home.
The only issue I’ve had so far was updating the firmware. I had to do it several times to take. In hindsight the fact was I hadn’t followed the instructions exactly, in terms of having a full battery and unplugging everything from the Delta Pro. Once I figured that out the update worked. It may be worth adding some kind of feedback in the app that tells the user that the update failed and possibly why it failed, if they don’t follow instructions like me.
For a home backup solution this thing rocks. I have heat, water, lights, and refrigeration for 8 hours or so if the power goes out. Obviously your times will vary, depending on your electrical use, but I did find that I use less electricity than I thought I did.
I highly recommend this item for a backup solution.
I would like to start out with the app which crosses over into the feature set. I’m an Android user and I find that most companies will focus more efforts on their iOS app; Android being “the red headed step child”. That is NOT the case with Ecoflow. I can’t speak to the iOS app, but their Android app is absolutely top notch. I would go so far as to say it’s in the top 5 apps, as far as user experience goes, that I’ve ever used.
Getting the device connected to WiFi, upgrading the firmware, and getting it set up is extremely intuitive, never had any issues or errors which are typical with other devices (not just power generators, but all devices that connect to WiFi). The intelligence to include a lower charge shut off and an upper charge shutoff tells me that they really considered the lifecycle of your investment. Additionally, you can limit the amount of wattage the devices charge at for their various charging methods, that’s just going above and beyond in my opinion. You don’t have to worry about tripping any breakers or anything like that.
As far as hardware goes, they’re pretty solid devices. From the rugged exterior and cables down to the quality of the LCD screen it’s all very well built. I LOVE that they had the forethought to include the collabsable handle and wheels because these suckers are HEAVY. On that note, I wish they put hand holds in the box that they come in. Carrying something that heavy and awkwardly sized to get it in the house and unboxed is a bit of a pain. I aggravated a knee injury in the process; although I’m partly to blame for that one. Simple perforations in the sides of the box for the hand holds like many other manufacturers of large gear would go a long way.
I’ll close with their customer service. I happened to catch this on a bundle + a deal that included a grounding module. Apparently, during checkout with Amazon, there was a checkbox that I didn’t check to opt in to this deal. When I contacted customer service, they pointed this out, but still asked me for my shipping address and sent me the grounding unit at no cost to me! Additionally, I’ve been contacted by them since receiving the bundle to make sure that I was all set and addressed the single question I had. I really ask that anyone reading this part goes back to the beginning of this paragraph and reads it again. When is the last time you got what you would consider even “adequate” customer service? When was the last time you got “good” or even “excellent” customer service? This is one of the best customer service experiences I’ve ever had if not THE best. I want to emphasize that they weren’t annoying about it either. I simply had a voicemail one day from them stating that they were just checking in to see if everything was working OK and if I had any questions to give them a call back. A single voicemail. No emails, no multiple phone calls, just a voicemail. Point is, I wasn’t being harassed. They just wanted to make sure that I was set with my investment.
Delta Pro 9/10
EcoFlow App 10/10
EcoFlow Company 11/10
I’m docking the Delta Pro a point for 2 reasons (and this really applies to the extended batteries as well). One being they could’ve put a little more thought into the cumbersome nature of moving the box around, simple perforated hand holds in the outer carboard box would’ve rectified this. Also to that point, it would be nice to have a less conspicuous box. Anyone within viewing range could’ve easily looked up what EcoFlow offers and known these boxes were worth stealing. The second reason I dock a point is that I’d like included is some dust & water resistant covers for USB and AC outlets. To charge the device, there’s a door that flips up (not spring loaded) so that’s at least a little protected. These are going to be in my basement and there’s going to be dust. I know they offer a pretty expensive cover for this reason but some removable rubber plugs I think is minimum as the cost of them justifies a little more forethought for protection of the power outputs.
I have already recommended them to anyone I’ve talked with looking for a power station, generator, or reliable battery backup for important electronics. Just this past week a tornado went through our neighborhood and someone was looking for backup suggestions because their sump pump went out and their basement flooded. I recommended the Delta 2 (the Delta Pro is a bit overkill for a sump pump).
Only 1 wk experience, but the unit is working fine. From a short (30min) test w/ 1.7 kW load, it has full rated capacity of 3.6 kWh. Didn’t expect it makes a fair amt of noise from fan during uses…it’s ok in garage, but can’t be in bedrms. Flexible way to charge…can add solar panels easily.
Biggest surprise in today’s marketplace…no 800 number to call. You need to email support. Got a reply saying answer will be coming in a few DAYS. (I was unaware that my powerline was defective and tried to ask why it’s not charging. After some tinkering, I found the problem and the unit charged ok.) Follow-up support has been prompt, so the lack of 800 number wasn’t such a problem after all.
Another surprise was the need to do “State of Charge Calibration” (SOC), which is not in the manual. This may to tough to understand for non-engineers, so a better write-up should be provided.
Despite these issues, it seems to be well built and I am hoping it will prepare us for power outages (becoming too often these days and for eventual post-EQ days).
AMAZING FOR TOU POWER PLANS! Great product, built like a tank (it even has wheels!) charges incredibly fast, I’m not using this as an emergency backup (although it will be amazing to have during one anyway), I’m using it as a solar generator. With power becoming more and more expensive – I wanted to find a way to decrease my bill and use the free natural solar power around my house. Hooking up 2x 400W Ecoflow solar panels in series, on a very sunny day I can charge this from 0-80% in around 6-7 hours, which means on sunny days I barely rely on grid power anymore. I was worried it would be too heavy to move around to use in different rooms, but the handle and wheels make it as easy as pulling a cart or wheelbarrow (it’s 99lbs, so not light, but I’m 5’6 and skinny and I had no problem picking it up)
It does get a bit noisy if you’re discharging or charging at above around 700-1000W, but its not a big deal if you use headphones, I’d rather it be safe and cool than have the chance of overheating.
I would recommend getting some solar if you buy this, if you’ve never used solar power before, it’s an amazing feeling knowing you’re using the energy that would have just been wasted into the ground, and this battery can power most houses for a full day. Ecoflow support have been incredibly helpful and kind, so if anything goes wrong I have trust that they would replace or help me fix the issue.
Brilliant Battery & solar generator - Not just for emergencies
Andere Speichersysteme sind preiswerter. Bluetti hat ein neues System auf dem Markt gebracht, was deutlich besser und preiswerter ist. Vor allem leichtere Batterien (Speicherelemente)
The plug and play nature of this system is super. You want more capacity, you just plug it in. I run my office from a Delta Pro and an extra Smart Battery.
But to start with, the extra battery was only utilised at half the rate it should be, leading to a State of Charge gap between the main unit and extra battery that increased over time. When the main unit reached 0%, it switched off, with the extra battery still showing 50% charge which is unusable as the main unit has shut down. This has been reported in forums by others for many months prior.
In reality the main unit hadn’t recalibrared itself after the extra battery was connected. The extra battery was supplying half the output power, but the main unit still seemed to think it was supplying it all on its own.
The solution: Force recalibration. Turn off anything being powered by the Delta Pro. Press the on/off button for 10 seconds. Wait a minute. Turn it back on. Voila, the units now show approximately equal states of charge and will utilise their capacity properly.
A really good battery system, despite early problems with usable capacity
Product bought as back up mainly for internet/ phones in case of power outage . Amazingly my house power was lost the day after I received it. It did it’s job beautifully and I calculated that would support my internet easily for 72 hours continuously so working from home has no worries.
With 4 mains outlets and a variety of useful others I could have plugged in a coffee machine and lighting at the same time. I’m considering their portable solar panel(s) and maybe a generator to take advantage of alternative charging. Well built, robust and heavy , on wheels so I can move it without great difficulty.
I’m hopeful it’ll be good for 10 years , we will have to see. My low level communication with the company was very good , quick friendly response.
What I like:
-Powerful at 3000w if you need to boil water/cook/run aircon offgrid.
-Powers almost anything a typical home would need in an extended powercut.
-No need to be an electrician to use the thing!
What I don’t like:
-Really, really expensive. Clatters when trying to move it, leaving me feeling dread that its not as sturdy as advertised.
-Noisy if you’re using over 90w of energy (I used it to power a 150w telly for a couple of days in September and the fans stayed on all the time)!!
-You need to app to access certain features. I wish this wasnt the case and we could access those features via the unit instead! Apps are fine, but those of us with ancient phones get left out, and for THIS price it SHOULD be accessible via the unit!
Would I recommend this? Yeah, if you have the spare cash to afford it. Might come of use when powercuts happen, keeping fridge and freezer running.
Da der Delta Pro ja eine recht hohe Verlustleistung (50W) hat geht ber den Tag ja schon zuviel Leistung ins nichts – ausserdem ist die % – und Lade-/Entladezeitanzeige fast vllig sinnlos, bei 99,49% ldt er noch Stunden weiter und bei 1% entldt er noch ca. 1,8kWh – damit war ein Zustazakku fllig, bei dem komischerweise die Anzeige dann aber stimmt. Der Delta Pro war schon zur “Reparatur” und wir mussten auf unsere Kosten eine kalibrierung vornehmen die aber leider auch nichts gendert hat. Mit dem Zusatzakku hat man dann wenigstens eine Vorstellung, wieviel Strom noch vorhanden ist…
A great unit does everything I could possibly want it to do, good build quality clear display Echoflow UK provide a good prompt service delivered on a small pallet because of the weight, it may shock you how heavy it is but it is a beautiful design and I couldn’t be happier with i
After considerable research and trawling user feedbacks on the internet regarding to Battery Systems, we have decided with EcoFlow’s Delta Pro and bought it to power our office with two 32′ 4K monitors with 16′ MacBook Pro M1 Pro. And wow we were blown away by every aspect of this product, it has to be the best battery system on the market currently. This review is for the quick initial 3-day since received it, will revert back with any further updates later on. Also shout out to their Customer Service whom had been great too, prompt to respond on any questions/doubt I had.
Quick summary: if you are looking for a long battery life (extended charge/discharge full cycle, Delta Pro support 3600 cycles still holds 80%+ capacity), high quality product with huge output capabilities for either portable or home off-grid use, Delta Pro is probably the best you can get. It can be charged via multiple input sources, and most useful with the inbuilt 1600w MPPT that any solar panel can charge it as easy as plug and play; another amazing capability is that it can be charged via electric vehicle charging point! We plan to get a second unit and possible 2 more battery packs to off-grid (at least summer time) powering our whole house/office. Unlike Tesla Wall, we can move these batteries anywhere we like with us and can always add required battery capacity (each unit being 3600w). The unit is heavy (as needed for the power capacity and better materials), delivery was super fast, next day for me (apparently the warehouse is near) and come well wrapped in a pallet as the unit weights 100pounds (49kg).
Detail breakdown:
First of all, Delta Pro’s build quality is amazing, really well build and felt very sturdy and well constructed. Although outside shell is plastic, I have seen video that they are made with honeycomb structure for added strength and being a 3600w battery, I also feel a bit more safe handle it. Unit come with few cable accessories and the EV charging adapter. Edit: correction – not EV charging adapter but was the Smart Generator Adapter. will have to separately purchase the ev charging adapter unfortunately.
Secondly, Delta Pro has huge capabilities and in emergency case can even power the small/medium ish house (but we have not tested this) with boost output of over 3600w sustained. It was a breeze for us to test everything we intended it to last 3days but not tumble drier as we dont have one. everything else in our office/house was handled with ease. It takes less than 2hours to completely fully charge up the unit via wall-socket with the standard power plug provided.
Thirdly, there are various of ways can charge up Delta Pro: solar panel, wall output, generators, ev charging points, ecoflow’s delta pro battery packs etc. We mostly using solar and connecting via standard MC4 connectors it was a simple plug and play as you can see from the screen prints that with our 320w solar panels, in cloudy vs full sunlight conditions both cases we can power our office whilst still charging Delta Pro!
Regarding the product’s ecosystem, there are additional battery packs can support 2 more with each Delta Pro bringing total battery capacity to over just 10kw (3.6k x 3) with simply plug and play; and can potentially have two Delta Pro in parallel to support up-to 7200w power for almost all domestic (even medium workshop) power needs. They have a smart house panel in the works apparently will make them Tesla Wall equal (but these have wheels can move with us on demand) – although I can’t wait further would go with a transfer switch to the consumer box route.
Finally, I found the EcoFlow app works well with the unit, can control all aspects of the operation and also have access to full info of the power usage/charging status etc etc.
Moving on to any other considerations, if anything I would say EcoFlow can improve on the fan noise, when it is charging/discharging more than 100ws, the fan kicks in to keep the unit cool but it is quite loud (for almost silent M1 Mac users). All in all, we are really impressed with EcoFlow and Delta Pro, will try to set it up for our off-grid living!
The best battery system can rival Tesla Wall and potentially allows electricity independence!
There is a design flaw with these units. You can’t use the battery while it is hooked up to AC charging. The input charge wattage is less than the output wattage. Shouldn’t be a big deal however when the unit is in bypass mode the wattage coming in to charge goes right to the output. Great feature except when you exceed the 1800 watt AC charge capacity. Setting the AC charge level restriction gets overwritten by this bypass mode. There is also no way to turn off the by pass mode either from the application. Could potentially cause a fire. My first unit started smoking. Luckily I was right there to turn it off.
Update: I was able to return both units without too much hassle. These units aren’t easy to ship back just because of how heavy they are. I have been happy with their customer support most of the time. Just when I think I have given up on them they surprise me with a nice email. I think the product is about 90% there with what I need. I am probably not their typical user. I wanted to plug in and draw from the batteries at the same time I was using an AC outlet. Why didn’t I just plug in directly into AC? I wanted to see what kind of load I was going to place on the unit in a real world situation while I figured out how much battery capacity I needed and the size of my solar array that I would eventually need to charge the batteries. The AC was supposed to be a stop gap while I was sizing my system.
I upgraded my review to 4 starts because of the positive customer service experience. I hope they address the issue I pointed out to them and wish them the best. It’s a well built unit it just didn’t operate the way I needed it to.
This battery is a BEAST and surprised me with its design. This is coming from someone who has reviewed over a dozen battery brands, including Goal Zero, Jackery, BigBlue, Rockpals, Aimtom, and the like. Goal Zero and Jackery are two of my favorites, but this Ecoflow surprised me indeed and has skyrocketed to one of the top brands I have tested and used thus far.
IN A NUTSHELL
The EcoFlow Delta Pro packs so many features and nuances, it took a surprisingly long time to summarize my thoughts for this review. It is one HECK of a beast of a power station! Although I was not able to test many of the capabilities due to my limited budget, reading and researching about some of the functions kept me in awe.
Goal Zero had been the gold standard for a long time with its market leading quality, safety record, and philanthropy roots, but the Delta Pro definitely should put the company on notice with an ecosystem that surprisingly surpassed Goal Zero’s in many ways. Offering a 3,600Wh battery capacity that could be expanded to 25,000Wh nearly doubles what Goal Zero could currently offer at 15,671Wh, and its AC inverter leapfrogs Goal Zero’s 2,000W of continuous power and 3,500W surge with double that: 3,600W and 7,200W, respectively. What that translates to is more devices and appliances that can be left running for many more days than homes with the Tesla Powerwall or large LG batteries commonly paired with home solar panels.
Specifications and numbers aside, the Delta Pro has an impressive set of input (charging) options, including AC wall, EV charger (a first!), solar, DC-producing gas generator, and possibly a wind turbine in the near future. What wowed me was the rapid charging capability when specific EcoFlow products are combined: 6,500W! Goal Zero’s best only charges at 600W, and two years ago, THAT number dropped my jaw. Charging a Delta Pro and Smart Extra Battery (7,200Wh) at 6,500W would take them from empty to full in less than 2 hours — SUPER impressive! Goal Zero’s 600W would have taken over 10 hours.
What additionally sets the Delta Pro apart is its Double Voltage Hub that can double the capacity and output of various Delta Pro product combinations. Tack on the Solar Tracker that uses a top-mounted sensor to follow the sun for maximum exposure, a Smart Generator that uses gasoline to produce DC power to directly feed into the Delta Pro, and you have a good support system to maximize battery capacity to run appliances with for longer, if not infinite, time periods.
A large, colorful display provides information about the battery’s status, and although it is beautiful, it lacks the details that Goal Zero’s higher-end products provide. EcoFlow makes up for that with its gorgeous smartphone app that also tracks historical data to help the owner make a variety of decisions from.
I really like the telescoping, retractable handle built into the EcoFlow: extend it to one of two lengths to tilt the battery backwards, then pull and roll the 99-pound Delta Pro across the house — at least, that’s the theory. Dragging the heavy battery on uneven grounds (like gravel) or traversing stairs is a huge challenge with the Pro’s small wheels. Did you notice the weight I had just mentioned? Ninety-nine pounds is no joke for the average person to carry up a flight of stairs! Goal Zero’s Roll Cart, on the other hand, with its larger wheels conquer those obstacles and surfaces with much more ease.
The EcoFlow tries to shed some of its LiFePO4 battery weight and cost by using a mostly plastic exterior. Although the Delta Pro still looks quite nice, Goal Zero’s Yeti X series is housed in a mostly metallic enclosure that helps dissipate heat and is more durable. Metal withstands impact force better than plastic, no doubt about that, but also adds weight. Two distinctive, exterior design philosophies each with their own pros and cons. Delta Pro is physically larger than the higher-capacity Yeti 6000X (6,071Wh), for some reason.
What surprised me despite all the impressive features of the 3,600Wh Delta Pro, it still costs just a little more than the lower-capacity, 3,032Wh Goal Zero Yeti 3000x. That makes it a great value!
Overall, it both pains and delights me to see the Delta Pro kicking Goal Zero’s Yeti X line to the curb. On one hand, Goal Zero now painfully looks a bit outdated, and on the other hand, Delta Pro has set a new bar that slaps Goal Zero in the face to wake up and innovate. Competition is always good for the consumer, and so, Goal Zero, what will you do next? EcoFlow has a winning product portfolio on its hands that is difficult to beat.
ANALYSIS
As one of Time Magazine’s “Best Inventions of 2021” under the “Sustainability” category, EcoFlow’s Delta Pro power station deservedly turned some heads. It certainly caught my attention with its wide list of features, expansion options, and accessories primarily geared for home use. Market leader, Goal Zero, offers a similar range of products, but EcoFlow does so in a sleeker — and at times more innovative — package. The configuration options gave me some struggles to write about while researching the Delta Pro because there were so MANY, most of which I could not test because it would have cost over $30,400 to collect the entire ecosystem for the “full experience”!
Bear with me! There is a LOT to discuss because of EcoFlow’s vast ecosystem of products. I will attempt to summarize the important ones and how they work with the Delta Pro.
Delta Max vs Pro: The Max is a smaller, lighter version of the Pro with less capacity at 2,016 Wh, a smaller AC inverter, and no transport wheels.
BATTERY CAPACITY
The Delta Pro offers 3,600 Watt-hours of battery capacity — how long something can run for — that can be expanded with up to two EcoFlow Smart Extra Batteries (3,600 Wh each) for a combined total of 10,800 Wh simply by connecting them with a pair of cables. That could power a typical home drawing 750-1,000W of power per hour for 10-12 hours. Double that to 21,600 Wh by linking another set of Delta Pro and 2 Extra Batteries via either the EcoFlow Smart Home Panel or the Double Voltage Hub. Finally, this can further be expanded to 25,000 Wh through the use of a Smart Home Panel, 2 Delta Pros, 2 Extra Batteries, and 2 EcoFlow Smart Generators — a gas-powered generator that produces virtually unlimited DC output (as long as gasoline is available) for more efficient charging of the Delta Pro.
Goal Zero can only store up to 10,871 Wh with a Yeti 6000X and 4 Yeti Tank Expansion Batteries. Let that sink in. The market leader is actually BEHIND in this area.
EcoFlow’s Smart Home Panel can power up to 10 electrical home circuits during a blackout, the Double Voltage Hub can double the Delta Pro’s capacity with the addition of another unit, and the Smart Generator can provide gas-generated DC power to the Delta Pro for more efficient charging. Furthermore, the generator can directly be controlled by the Delta Pro so it would only be started when needed.
POWER OUTPUT
Another area the Delta Pro shines at is what devices — and how many of them — it can power at the same time. Its AC inverter can operate at a continuous 3,600W of energy and surge up to 7,200W. If those numbers do not make sense to you, do not worry. I will go over Continuous vs Peak (Surge) in more detail later.
You can throw a number of high-powered devices, like a home air conditioner, refrigerator, TV, laptop, and hair dryer at it with no problem whatsoever as long as their combined power usage does not exceed 3,600W. The Continuous output can be expanded to 4,500W with X-Boost, or 7,200W by combining 2 Delta Pros with either a Smart Home Panel or Double Voltage Hub.
Goal Zero’s flagship Yeti 6000X can only go 2,000W continuously and peak at 3,500W — numbers that were impressive and unheard of when the product was announced in 2020.
BATTERY TECHNOLOGY
There has been a lot of debate on whether Nickel Manganese Cobalt (NMC) or Lithium Iron Phosphate (LiFePO4) — both are Lithium-ion (Li-ion) — is better. Goal Zero, Jackery, and most of today’s power station manufacturers use NMC, but why do EcoFlow and Bluetti use Li-ion LiFePO4 when they are bulkier and heavier? They hold some important advantages over Li-ion NMC:
– Safer, less volatile, and thus cheaper to manufacture
– Charge cycle: 1500-2000 (10+ years)
— NMC: 20-25% capacity loss after every 500 cycle (6-10 years for up to 2000 cycles, after which capacity is vastly diminished)
— EcoFlow claims 3500 cycles before dropping to 80% of original capacity and 6500 to 50%. Those are some VERY optimistic projections that I do not think are accurate in actual usage
– Usable in more extreme temperatures (-4F/-20C to 176F/80C). NMC: only 140F/60C max
– Holds 350-day charge. NMC: 300
AC CHARGING SPEEDS
Tip: A record-breaking input of 6,500W (!) can be achieved by combining AC + Solar + Smart Generator charging! (A Smart Extra Battery must be connected to the Delta Pro for this to work.)
The back of the Delta Pro has a toggle for how much power it should draw for charging: Fast or Slow/Custom.
– Fast: 1,800W (120V @ 15A) or 3,000W (240V @ 12.5A)
— 0-80% in 2 hours and to 100% after another 45 mins
– Slow/Custom: 200W — 1,800W
— Slow charging is gentler on the battery, prolongs its lifetime, and minimizes risk of tripping the circuit breaker
— Custom allows the Delta to charge at a configured rate so the wall circuit would not be overloaded. That’s an EXCELLENT feature to have!
— Example: If an AC Circuit can only handle 1,200W and a coffee maker uses 800W, then the Delta Pro should be configured to charge at no more than 400W (1,200W — 800W)
— Configurable through the EcoFlow app
Tip: AC charging is prioritized over DC when both are connected simultaneously. Never use an extension cord to charge the Delta Pro with unless it’s a heavy-duty one.
If the Delta Pro is used in pass-through UPS (uninterruptible power supply) mode, the internal circuit will turn off its inverter if it detects the AC wall outlet getting overloaded (ie. passing through more than 20A). This means that it could shut off at 1,200W without ever reaching its 3,600W capacity. To use the full 3,600W, disconnect it from the wall and let the battery provide that power.
Note: Using a battery as a UPS (charging and outputting at the same time) could shorten its lifetime.
PROS
– Impressive battery capacity (3,600Wh — 25,000Wh)
— Superfast, configurable charging speeds (200W — 1,800W or up to 6,500W under specific conditions!)
– LiFePO4 technology provides for 10+ years of power
— Up to 2,000 — 3,000 cycles based on my research (I do not believe EcoFlow’s claim of lasting much longer than 6,500 cycles. Hope they prove me wrong 15-20 years from now!)
— Much safer and stable than Lithium-ion NMC
– Large AC inverter with continuous 3,600W (7,200W peak) of output
— Enough to power a typical home for days — or, when used with the EcoFlow (Gas) Smart Generator and/or set of solar panels, virtually forever
— Pure-Sine Wave AC Inverter
— Clean power for sensitive electronics
— Less heat
— Note: Some manufacturers claim to be Pure-Sine when they are actually Modified or Square Waves
– High-quality BMS (Battery Management System) for safety
— Provides built-in overload, overcharge (automatic stop when the device is full), and short-circuit protection
– Expansion/augmentation ecosystem with EF Solar Panels, Double Voltage Hub, Smart Generator, Extra Smart Batteries, Smart Home Panel, wind turbine (not yet available), EV charging station, and Remote Control
– Impressive input and output options, including a NEMA 30A for RV hookup
— Up to 1,600W of solar charging
– Carry handle is strong enough to run a cable lock through for theft deterrence
– Can be used in pass-through UPS mode, though that can shorten the battery’s lifetime
– Beautiful, large, color information display
– Built-in, retractable handle
– Wheels for easier transportation
– Strong Research & Development and Engineering teams who create innovations that Goal Zero, Jackery/Generark, and Bluetti cannot ignore
— Competition hopefully continues to spur better products from all companies
– Beautiful, informative EcoFlow smartphone app with historical data (for Apple iOS and Android)
CONS
– Heaviest power station (99 lbs) I have ever reviewed
— Weight is due to the use of 3,600Wh of LiFePO4 battery cells instead of NMC
— Comparison: Goal Zero, despite using a more heavy-duty, metallic enclosure, has the Yeti 3000X (3,032Wh) weigh at 70lbs, Yeti 6000X (6,071Wh) at 106 lbs
— Difficult to move up stairs, lifting onto truck bed, or pulling across gravel ground — especially with the small wheels
– Plastic enclosure helps shed some weight but is not as heavy-duty as Goal Zero’s Yeti X line
– Bulkier than Goal Zero’s Yeti 3000X and 6000X
— Although I was not able to borrow my friend’s Goal Zero Yeti 6000X for a full comparison review, I took a photo of the Delta Pro next to it for size comparison
– Outputs 3,600W continuously only if powered from its battery and not in a 120V UPS pass-through configuration
– No vehicle integration kit
– Cable to link Delta Pro with additional Smart Batteries is too short, limiting how and where the batteries can be placed
– Car Cigarette Port only accepts 96W of input at 12V
— Goal Zero Yeti X and Jackery Explorer series can take 120W (12V @ 10A)
– Many configuration options are only available through the EcoFlow smartphone app and not from the Delta Pro itself
– Anderson Power Pole (APP) solar part is configured vertically (like Goal Zero, but in reverse)
— Most companies arrange APP horizontally
— Can be remediated by buying an APP extension cable, such as those by iGreely, and re-arranging it
– Manual: Not as detailed and as many helpful tips as Goal Zero’s
– Not an American company
– Not waterproof. Keep it away from water splashes, rain, and pool!
USAGE
CONTINUOUS VS PEAK OUTPUT
It is important to understand the difference between Watts and Watt-Hours. How much power is used or produced is measured in Watts, and how much energy a battery can store is calculated in Watt-Hours. See the “Calculations” section below for more details.
How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).
– AC Inverter: Converts battery (DC) power into AC
— Delta Pro provides 3,600W continuous output with a 7,200W peak
– Peak/Surge (Starting): Nearly every device initially draws extra power to turn on. The highest amount it pulls is the Peak. As long as that number is below 7,200W, it can be STARTED. Because the Delta Pro’s capacity is so high, it is difficult to provide examples for devices that start at over 7,200W. So, to illustrate the concept, I will use the Goal Zero Yeti 1000 Core’s specs (2,400W peak and 1,200W continuous) as examples.
— Turns on OK (PEAK under 2,400W):
— Freezer starts at 400W (peak), runs at 150W once on
— Coffee maker starts at 1,400W (peak), runs at 800W once on
— Will NOT turn on (PEAK over 2,400W):
— Home AC starts at 4,000W (peak), runs at 1,000W once on
Most devices power on at a higher (Peak) wattage than when they are already on (Continuous). Therefore, if its peak exceeds the power station’s max, it may not be able to start
– Continuous Output (Running): Once devices are on, as long as they keep drawing less than 3,600W total, they will stay ON until the battery runs out
— CONTINUES running (under 3,600W)
— 100W TV + 60W laptop = 160W
— COULD STOP running (over 3,600W)
— Temporary overdrawing beyond 3,600W for a few seconds is okay. A quality BMS will protectively shut down the battery if the surge does not end after a while. Regularly going over for a prolonged time can ruin the battery in the long run
— 300W appliance (500W peak) + 1,000W Home AC (4,000W peak) + 800W Coffee maker (1,400W peak) + 1,200W Miter saw (2,400W peak) + 400W appliance = 3,700W. Probably will stay on for a short period
—- Add 1,000W mower (1,400W peak) = 4,700W. Battery will definitely shut down
CALCULATIONS – SIZE & TIME
What size battery should you get? How long will it power your fridge for? How long will it take to recharge? The below calculations can help answer those questions and are rough ESTIMATES as conditions, battery quality, and age can vary.
TIME TO CHARGE BATTERY
– Calc: Hours to charge battery = Battery capacity (Wh) / Input Wattage
— Note: As battery approaches 75% full, the input charge will increasingly be slowed down to prevent overcharging
– AC Wall: 1,800W @ 2 hrs [3,600 Wh / 1,800W]
CHARGE TIME WITH SOLAR
– Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])
— In a perfect lab environment, solar panels charge at the listed wattage
— Expect to only receive 50-75% on a good, sunny day (ie. 75W — 113W for a 150W panel), depending on panel’s age, component quality, and weather
– Two 400W solar panels: as fast as 6 hours [3,600Wh / (2 x 400W x 0.75)]
WATTS USED/PRODUCED
– Calc: Watts used or produced by device = Voltage x Amperage
– Vacuum with 120V @ 9.5A uses 1,140W
– Solar panel with 12V @ 10A can produce up to 120W
IDEAL BATTERY SIZE
– Calc: Battery capacity (Wh) = Watts used by device x Hours needed for / 0.85
— 10-15% of power is lost during power conversion
– 45W car fridge needed for 8 hours: Minimum 424Wh power station (45W x 8 / 0.85)
How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).
TIME BEFORE BATTERY IS EMPTY
– Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device
— 10-15% of power is lost during power conversion
– 60W laptop with 505Wh battery: Up to 7.2 hours (505Wh x 0.85 / 60W)
TIME TO CHARGE DEVICE
– Calc: Hours to charge device = Device’s battery capacity (Wh) / Input Wattage
– 60W laptop with 200Wh battery: Up to 3.4 hrs (200 Wh / 60W)
Blew my mind. Am a loyal Goal Zero/Jackery fan, but add Ecoflow to my small list now
Heavy duty battery, high quality that can be recharged with solar panels (extra, not included) to provide days long power for essentials like a refrigerator and/or freezer and a couple of lamps if you lose power due to a Russian cyber attack on the electric grid or affected by a nuclear strike not directly on you.
I did all the research of competing products available and for something thats portable and relatively affordable this is the best product for you to give much needed peace of mind. It was a Time magazine 100 top invention of last year, so that should give you the confidence.
To charge with sun you will need to do some research and spend an approximate additional $1,000 for solar panels, cords, connectors and stands to produce 800W to 1200W for expedited solar charging. YouTube has videos on how to hook everything up. Myself I bought HQST 100 watt panels to mount on vertical poles that can be manually rotated throughout the day to follow the sun for maximum charging experience.
Don’t let World War III catch you off guard with no power, no lights and rotting food in your refrigerator. Eating canned food by candlelight is poor way of life. Your neighbors will envy your home with lights and they have none but be careful they may want to visit and take what you have. You will need to make preparations for this too.
Generator worked as advertised. I love everything about it. I lost power at home and was able to plug in 2 refrigerators and other important items so I could operate close to normal during the 12+ hour power outage. I ordered another generator and now I’m waiting for the batteries to arrive so I can have a whole home back up system in case this happens again.
After getting this I realized how nice it would be to run my 240V range when the grid goes out so I got a second one and paired them with the Ecoflow double voltage hub. So now I have twice the power and twice the runtime. So technically I can now also run my water heater and HVAC with a soft start.
There are other brands out there and you can always put together a DIY but I was impressed by how smart and portable this thing is. Then there is the fast charge, the solar input, the Lipo4 batteries which offers well over a decade of service. Too many features to mention.
I’m not trying to sound like a show off but there is something about being able to just flip the light switches anywhere in your house when the rest of the community is it darkness. Makes you feel like you did your family proud. I also ordered the smart panel so even without power cuts I will be able to charge this unit off peak and feed of the battery on peak. This is one of the best purchases I’ve made this year. Whether is natural disaster, business or recreation now I feel prepared.
Nice and compact but heavy so good to have the wheels. Charged it with re solar panels and it works great so far. Got the wrong switchover panel that was included and am returning to get right one but have high hopes for the generator. Seems well thought out and solidly built. Easyto connect to internet with the App.
Off button for turnnng ac on and off; would rather have a covered switch. Lots of different types of charging and powering options built in.
Depending on what you are running, it will only last you a a day or two without needing to be re-charged, but most power outages do not lost longer than that. You can also get a solar charger for the system, which I have not tried yet. You can also get expanded batteries to give you expanded backup time.
Check out the You Tube videos that are put out by EcoFlow on the use of the battery and specifically the installation of the transfer switch; they is very informative, and worth the viewing time.
Easy to plug in to charge. Used to keep the fridge going during blackouts (for ~24 hrs). Has multiple USB charging ports as well as multiple outlets. Kind of heavy, so it may be hard to lift and carry but has wheels that facilitate transport. Overall good product to have as backup if your areas are prone to losing power.
I could write a book but instead of listing all the good, I’ll focus on what I’d improve.
1. Higher direct DC output. 30A is ok but to replace RV batteries without wasting power with AC conversion, a high amperage 100A + direct DC output would be great. 2. More Solar inputs. 1600W (150V 15A max) is good but makes panel selection more difficult. I’d like to see a multiple input MPPT to make it easier to maximize the solar input. 3. Fan noise. When charging over 900W or so the fan noise is very noticeable. (The Delta 2 Max can charge at 1000W and is nearly silent)
So, for the endless list of good this thing does, these are my wishes to Ecoflow for further development.
We can address the 100 lb elephant in the room. This thing is heavy. For what you get, they have done an excellent job making it portable though. The handles and wheels work great. If you want a more manageable system with nearly the same capability, the Delta 2 or Delta 2 Max and extra battery are a good option.
Full disclosure, I bought this unit with my own money. Ecoflow did ask me to write a review for a small compensation. (This did not influence my review as I was going to post one anyway.)
Comes in handy during power outages. Had one that lasted 24hr and was able to keep the fridge on and food from goiing bad, didn’t need to get dry ice which the stores already ran out of. Planning to expand the system with extra banks or maybe solar when they go on sale again. Shout out to 8-bit guy.
I do have two minor suggestions.
1. There is a tiny white light on the front of the panel that slowly fades in and out when in use. (i.e. charging phone overnight). The only way to negate this was to cover the light. “Dark Mode” would be nice.
2. A longer AC power cord. RV outlets aren’t in the most convenient locations, so an extra long cord would be helpful so that I don’t have to lift the (99 lb) power station onto a table to reach the outlet. (or use an extension cord).
Have not been able to get this set up due to met helper being tied up on other Jos.
Shipping was prompt and this seems to be well built and I am very anxious to get it going.
Delta Pro was great for 9 months. Then I purchased their 400w solar panel and it fried my Delta Pro. Now I can’t seem to get a response from customer service on how they will fix this warranty issue. They need to reduce the marketing budget and increase the support budget.
When you spend this much money on a product, you are also purchasing the customer service. That part of the product is poor and would cause me to NOT recommend any of their products
La trape se trouve au dessus de la batterir.
Original review:
My initial take on this is that it is a very well made piece of equipment. The related android app is also steller. I currently have it integrated with a smart home panel and at the touch of a button, or an unexpected power outage, this takes over one or all of the 110 volt circuits in my home.
The only issue I’ve had so far was updating the firmware. I had to do it several times to take. In hindsight the fact was I hadn’t followed the instructions exactly, in terms of having a full battery and unplugging everything from the Delta Pro. Once I figured that out the update worked. It may be worth adding some kind of feedback in the app that tells the user that the update failed and possibly why it failed, if they don’t follow instructions like me.
For a home backup solution this thing rocks. I have heat, water, lights, and refrigeration for 8 hours or so if the power goes out. Obviously your times will vary, depending on your electrical use, but I did find that I use less electricity than I thought I did.
I highly recommend this item for a backup solution.
Getting the device connected to WiFi, upgrading the firmware, and getting it set up is extremely intuitive, never had any issues or errors which are typical with other devices (not just power generators, but all devices that connect to WiFi). The intelligence to include a lower charge shut off and an upper charge shutoff tells me that they really considered the lifecycle of your investment. Additionally, you can limit the amount of wattage the devices charge at for their various charging methods, that’s just going above and beyond in my opinion. You don’t have to worry about tripping any breakers or anything like that.
As far as hardware goes, they’re pretty solid devices. From the rugged exterior and cables down to the quality of the LCD screen it’s all very well built. I LOVE that they had the forethought to include the collabsable handle and wheels because these suckers are HEAVY. On that note, I wish they put hand holds in the box that they come in. Carrying something that heavy and awkwardly sized to get it in the house and unboxed is a bit of a pain. I aggravated a knee injury in the process; although I’m partly to blame for that one. Simple perforations in the sides of the box for the hand holds like many other manufacturers of large gear would go a long way.
I’ll close with their customer service. I happened to catch this on a bundle + a deal that included a grounding module. Apparently, during checkout with Amazon, there was a checkbox that I didn’t check to opt in to this deal. When I contacted customer service, they pointed this out, but still asked me for my shipping address and sent me the grounding unit at no cost to me! Additionally, I’ve been contacted by them since receiving the bundle to make sure that I was all set and addressed the single question I had. I really ask that anyone reading this part goes back to the beginning of this paragraph and reads it again. When is the last time you got what you would consider even “adequate” customer service? When was the last time you got “good” or even “excellent” customer service? This is one of the best customer service experiences I’ve ever had if not THE best. I want to emphasize that they weren’t annoying about it either. I simply had a voicemail one day from them stating that they were just checking in to see if everything was working OK and if I had any questions to give them a call back. A single voicemail. No emails, no multiple phone calls, just a voicemail. Point is, I wasn’t being harassed. They just wanted to make sure that I was set with my investment.
Delta Pro 9/10
EcoFlow App 10/10
EcoFlow Company 11/10
I’m docking the Delta Pro a point for 2 reasons (and this really applies to the extended batteries as well). One being they could’ve put a little more thought into the cumbersome nature of moving the box around, simple perforated hand holds in the outer carboard box would’ve rectified this. Also to that point, it would be nice to have a less conspicuous box. Anyone within viewing range could’ve easily looked up what EcoFlow offers and known these boxes were worth stealing. The second reason I dock a point is that I’d like included is some dust & water resistant covers for USB and AC outlets. To charge the device, there’s a door that flips up (not spring loaded) so that’s at least a little protected. These are going to be in my basement and there’s going to be dust. I know they offer a pretty expensive cover for this reason but some removable rubber plugs I think is minimum as the cost of them justifies a little more forethought for protection of the power outputs.
I have already recommended them to anyone I’ve talked with looking for a power station, generator, or reliable battery backup for important electronics. Just this past week a tornado went through our neighborhood and someone was looking for backup suggestions because their sump pump went out and their basement flooded. I recommended the Delta 2 (the Delta Pro is a bit overkill for a sump pump).
A great piece of equipment with a variety of sockets. I just wish the app would allow to turn the 240v sockets individually instead of all on/all off
Biggest surprise in today’s marketplace…no 800 number to call. You need to email support. Got a reply saying answer will be coming in a few DAYS. (I was unaware that my powerline was defective and tried to ask why it’s not charging. After some tinkering, I found the problem and the unit charged ok.) Follow-up support has been prompt, so the lack of 800 number wasn’t such a problem after all.
Another surprise was the need to do “State of Charge Calibration” (SOC), which is not in the manual. This may to tough to understand for non-engineers, so a better write-up should be provided.
Despite these issues, it seems to be well built and I am hoping it will prepare us for power outages (becoming too often these days and for eventual post-EQ days).
It does get a bit noisy if you’re discharging or charging at above around 700-1000W, but its not a big deal if you use headphones, I’d rather it be safe and cool than have the chance of overheating.
I would recommend getting some solar if you buy this, if you’ve never used solar power before, it’s an amazing feeling knowing you’re using the energy that would have just been wasted into the ground, and this battery can power most houses for a full day. Ecoflow support have been incredibly helpful and kind, so if anything goes wrong I have trust that they would replace or help me fix the issue.
But to start with, the extra battery was only utilised at half the rate it should be, leading to a State of Charge gap between the main unit and extra battery that increased over time. When the main unit reached 0%, it switched off, with the extra battery still showing 50% charge which is unusable as the main unit has shut down. This has been reported in forums by others for many months prior.
In reality the main unit hadn’t recalibrared itself after the extra battery was connected. The extra battery was supplying half the output power, but the main unit still seemed to think it was supplying it all on its own.
The solution: Force recalibration. Turn off anything being powered by the Delta Pro. Press the on/off button for 10 seconds. Wait a minute. Turn it back on. Voila, the units now show approximately equal states of charge and will utilise their capacity properly.
Product bought as back up mainly for internet/ phones in case of power outage . Amazingly my house power was lost the day after I received it. It did it’s job beautifully and I calculated that would support my internet easily for 72 hours continuously so working from home has no worries.
With 4 mains outlets and a variety of useful others I could have plugged in a coffee machine and lighting at the same time. I’m considering their portable solar panel(s) and maybe a generator to take advantage of alternative charging. Well built, robust and heavy , on wheels so I can move it without great difficulty.
I’m hopeful it’ll be good for 10 years , we will have to see. My low level communication with the company was very good , quick friendly response.
-Powerful at 3000w if you need to boil water/cook/run aircon offgrid.
-Powers almost anything a typical home would need in an extended powercut.
-No need to be an electrician to use the thing!
What I don’t like:
-Really, really expensive. Clatters when trying to move it, leaving me feeling dread that its not as sturdy as advertised.
-Noisy if you’re using over 90w of energy (I used it to power a 150w telly for a couple of days in September and the fans stayed on all the time)!!
-You need to app to access certain features. I wish this wasnt the case and we could access those features via the unit instead! Apps are fine, but those of us with ancient phones get left out, and for THIS price it SHOULD be accessible via the unit!
Would I recommend this? Yeah, if you have the spare cash to afford it. Might come of use when powercuts happen, keeping fridge and freezer running.
A great unit does everything I could possibly want it to do, good build quality clear display Echoflow UK provide a good prompt service delivered on a small pallet because of the weight, it may shock you how heavy it is but it is a beautiful design and I couldn’t be happier with i
Fantastic product, would like to have been able to speak to a real person, to get issue sorted out sooner.
Quick summary: if you are looking for a long battery life (extended charge/discharge full cycle, Delta Pro support 3600 cycles still holds 80%+ capacity), high quality product with huge output capabilities for either portable or home off-grid use, Delta Pro is probably the best you can get. It can be charged via multiple input sources, and most useful with the inbuilt 1600w MPPT that any solar panel can charge it as easy as plug and play; another amazing capability is that it can be charged via electric vehicle charging point! We plan to get a second unit and possible 2 more battery packs to off-grid (at least summer time) powering our whole house/office. Unlike Tesla Wall, we can move these batteries anywhere we like with us and can always add required battery capacity (each unit being 3600w). The unit is heavy (as needed for the power capacity and better materials), delivery was super fast, next day for me (apparently the warehouse is near) and come well wrapped in a pallet as the unit weights 100pounds (49kg).
Detail breakdown:
First of all, Delta Pro’s build quality is amazing, really well build and felt very sturdy and well constructed. Although outside shell is plastic, I have seen video that they are made with honeycomb structure for added strength and being a 3600w battery, I also feel a bit more safe handle it. Unit come with few cable accessories and the EV charging adapter. Edit: correction – not EV charging adapter but was the Smart Generator Adapter. will have to separately purchase the ev charging adapter unfortunately.
Secondly, Delta Pro has huge capabilities and in emergency case can even power the small/medium ish house (but we have not tested this) with boost output of over 3600w sustained. It was a breeze for us to test everything we intended it to last 3days but not tumble drier as we dont have one. everything else in our office/house was handled with ease. It takes less than 2hours to completely fully charge up the unit via wall-socket with the standard power plug provided.
Thirdly, there are various of ways can charge up Delta Pro: solar panel, wall output, generators, ev charging points, ecoflow’s delta pro battery packs etc. We mostly using solar and connecting via standard MC4 connectors it was a simple plug and play as you can see from the screen prints that with our 320w solar panels, in cloudy vs full sunlight conditions both cases we can power our office whilst still charging Delta Pro!
Regarding the product’s ecosystem, there are additional battery packs can support 2 more with each Delta Pro bringing total battery capacity to over just 10kw (3.6k x 3) with simply plug and play; and can potentially have two Delta Pro in parallel to support up-to 7200w power for almost all domestic (even medium workshop) power needs. They have a smart house panel in the works apparently will make them Tesla Wall equal (but these have wheels can move with us on demand) – although I can’t wait further would go with a transfer switch to the consumer box route.
Finally, I found the EcoFlow app works well with the unit, can control all aspects of the operation and also have access to full info of the power usage/charging status etc etc.
Moving on to any other considerations, if anything I would say EcoFlow can improve on the fan noise, when it is charging/discharging more than 100ws, the fan kicks in to keep the unit cool but it is quite loud (for almost silent M1 Mac users). All in all, we are really impressed with EcoFlow and Delta Pro, will try to set it up for our off-grid living!
Update: I was able to return both units without too much hassle. These units aren’t easy to ship back just because of how heavy they are. I have been happy with their customer support most of the time. Just when I think I have given up on them they surprise me with a nice email. I think the product is about 90% there with what I need. I am probably not their typical user. I wanted to plug in and draw from the batteries at the same time I was using an AC outlet. Why didn’t I just plug in directly into AC? I wanted to see what kind of load I was going to place on the unit in a real world situation while I figured out how much battery capacity I needed and the size of my solar array that I would eventually need to charge the batteries. The AC was supposed to be a stop gap while I was sizing my system.
I upgraded my review to 4 starts because of the positive customer service experience. I hope they address the issue I pointed out to them and wish them the best. It’s a well built unit it just didn’t operate the way I needed it to.
IN A NUTSHELL
The EcoFlow Delta Pro packs so many features and nuances, it took a surprisingly long time to summarize my thoughts for this review. It is one HECK of a beast of a power station! Although I was not able to test many of the capabilities due to my limited budget, reading and researching about some of the functions kept me in awe.
Goal Zero had been the gold standard for a long time with its market leading quality, safety record, and philanthropy roots, but the Delta Pro definitely should put the company on notice with an ecosystem that surprisingly surpassed Goal Zero’s in many ways. Offering a 3,600Wh battery capacity that could be expanded to 25,000Wh nearly doubles what Goal Zero could currently offer at 15,671Wh, and its AC inverter leapfrogs Goal Zero’s 2,000W of continuous power and 3,500W surge with double that: 3,600W and 7,200W, respectively. What that translates to is more devices and appliances that can be left running for many more days than homes with the Tesla Powerwall or large LG batteries commonly paired with home solar panels.
Specifications and numbers aside, the Delta Pro has an impressive set of input (charging) options, including AC wall, EV charger (a first!), solar, DC-producing gas generator, and possibly a wind turbine in the near future. What wowed me was the rapid charging capability when specific EcoFlow products are combined: 6,500W! Goal Zero’s best only charges at 600W, and two years ago, THAT number dropped my jaw. Charging a Delta Pro and Smart Extra Battery (7,200Wh) at 6,500W would take them from empty to full in less than 2 hours — SUPER impressive! Goal Zero’s 600W would have taken over 10 hours.
What additionally sets the Delta Pro apart is its Double Voltage Hub that can double the capacity and output of various Delta Pro product combinations. Tack on the Solar Tracker that uses a top-mounted sensor to follow the sun for maximum exposure, a Smart Generator that uses gasoline to produce DC power to directly feed into the Delta Pro, and you have a good support system to maximize battery capacity to run appliances with for longer, if not infinite, time periods.
A large, colorful display provides information about the battery’s status, and although it is beautiful, it lacks the details that Goal Zero’s higher-end products provide. EcoFlow makes up for that with its gorgeous smartphone app that also tracks historical data to help the owner make a variety of decisions from.
I really like the telescoping, retractable handle built into the EcoFlow: extend it to one of two lengths to tilt the battery backwards, then pull and roll the 99-pound Delta Pro across the house — at least, that’s the theory. Dragging the heavy battery on uneven grounds (like gravel) or traversing stairs is a huge challenge with the Pro’s small wheels. Did you notice the weight I had just mentioned? Ninety-nine pounds is no joke for the average person to carry up a flight of stairs! Goal Zero’s Roll Cart, on the other hand, with its larger wheels conquer those obstacles and surfaces with much more ease.
The EcoFlow tries to shed some of its LiFePO4 battery weight and cost by using a mostly plastic exterior. Although the Delta Pro still looks quite nice, Goal Zero’s Yeti X series is housed in a mostly metallic enclosure that helps dissipate heat and is more durable. Metal withstands impact force better than plastic, no doubt about that, but also adds weight. Two distinctive, exterior design philosophies each with their own pros and cons. Delta Pro is physically larger than the higher-capacity Yeti 6000X (6,071Wh), for some reason.
What surprised me despite all the impressive features of the 3,600Wh Delta Pro, it still costs just a little more than the lower-capacity, 3,032Wh Goal Zero Yeti 3000x. That makes it a great value!
Overall, it both pains and delights me to see the Delta Pro kicking Goal Zero’s Yeti X line to the curb. On one hand, Goal Zero now painfully looks a bit outdated, and on the other hand, Delta Pro has set a new bar that slaps Goal Zero in the face to wake up and innovate. Competition is always good for the consumer, and so, Goal Zero, what will you do next? EcoFlow has a winning product portfolio on its hands that is difficult to beat.
ANALYSIS
As one of Time Magazine’s “Best Inventions of 2021” under the “Sustainability” category, EcoFlow’s Delta Pro power station deservedly turned some heads. It certainly caught my attention with its wide list of features, expansion options, and accessories primarily geared for home use. Market leader, Goal Zero, offers a similar range of products, but EcoFlow does so in a sleeker — and at times more innovative — package. The configuration options gave me some struggles to write about while researching the Delta Pro because there were so MANY, most of which I could not test because it would have cost over $30,400 to collect the entire ecosystem for the “full experience”!
Bear with me! There is a LOT to discuss because of EcoFlow’s vast ecosystem of products. I will attempt to summarize the important ones and how they work with the Delta Pro.
Delta Max vs Pro: The Max is a smaller, lighter version of the Pro with less capacity at 2,016 Wh, a smaller AC inverter, and no transport wheels.
BATTERY CAPACITY
The Delta Pro offers 3,600 Watt-hours of battery capacity — how long something can run for — that can be expanded with up to two EcoFlow Smart Extra Batteries (3,600 Wh each) for a combined total of 10,800 Wh simply by connecting them with a pair of cables. That could power a typical home drawing 750-1,000W of power per hour for 10-12 hours. Double that to 21,600 Wh by linking another set of Delta Pro and 2 Extra Batteries via either the EcoFlow Smart Home Panel or the Double Voltage Hub. Finally, this can further be expanded to 25,000 Wh through the use of a Smart Home Panel, 2 Delta Pros, 2 Extra Batteries, and 2 EcoFlow Smart Generators — a gas-powered generator that produces virtually unlimited DC output (as long as gasoline is available) for more efficient charging of the Delta Pro.
Goal Zero can only store up to 10,871 Wh with a Yeti 6000X and 4 Yeti Tank Expansion Batteries. Let that sink in. The market leader is actually BEHIND in this area.
EcoFlow’s Smart Home Panel can power up to 10 electrical home circuits during a blackout, the Double Voltage Hub can double the Delta Pro’s capacity with the addition of another unit, and the Smart Generator can provide gas-generated DC power to the Delta Pro for more efficient charging. Furthermore, the generator can directly be controlled by the Delta Pro so it would only be started when needed.
POWER OUTPUT
Another area the Delta Pro shines at is what devices — and how many of them — it can power at the same time. Its AC inverter can operate at a continuous 3,600W of energy and surge up to 7,200W. If those numbers do not make sense to you, do not worry. I will go over Continuous vs Peak (Surge) in more detail later.
You can throw a number of high-powered devices, like a home air conditioner, refrigerator, TV, laptop, and hair dryer at it with no problem whatsoever as long as their combined power usage does not exceed 3,600W. The Continuous output can be expanded to 4,500W with X-Boost, or 7,200W by combining 2 Delta Pros with either a Smart Home Panel or Double Voltage Hub.
Goal Zero’s flagship Yeti 6000X can only go 2,000W continuously and peak at 3,500W — numbers that were impressive and unheard of when the product was announced in 2020.
BATTERY TECHNOLOGY
There has been a lot of debate on whether Nickel Manganese Cobalt (NMC) or Lithium Iron Phosphate (LiFePO4) — both are Lithium-ion (Li-ion) — is better. Goal Zero, Jackery, and most of today’s power station manufacturers use NMC, but why do EcoFlow and Bluetti use Li-ion LiFePO4 when they are bulkier and heavier? They hold some important advantages over Li-ion NMC:
– Safer, less volatile, and thus cheaper to manufacture
– Charge cycle: 1500-2000 (10+ years)
— NMC: 20-25% capacity loss after every 500 cycle (6-10 years for up to 2000 cycles, after which capacity is vastly diminished)
— EcoFlow claims 3500 cycles before dropping to 80% of original capacity and 6500 to 50%. Those are some VERY optimistic projections that I do not think are accurate in actual usage
– Usable in more extreme temperatures (-4F/-20C to 176F/80C). NMC: only 140F/60C max
– Holds 350-day charge. NMC: 300
AC CHARGING SPEEDS
Tip: A record-breaking input of 6,500W (!) can be achieved by combining AC + Solar + Smart Generator charging! (A Smart Extra Battery must be connected to the Delta Pro for this to work.)
The back of the Delta Pro has a toggle for how much power it should draw for charging: Fast or Slow/Custom.
– Fast: 1,800W (120V @ 15A) or 3,000W (240V @ 12.5A)
— 0-80% in 2 hours and to 100% after another 45 mins
– Slow/Custom: 200W — 1,800W
— Slow charging is gentler on the battery, prolongs its lifetime, and minimizes risk of tripping the circuit breaker
— Custom allows the Delta to charge at a configured rate so the wall circuit would not be overloaded. That’s an EXCELLENT feature to have!
— Example: If an AC Circuit can only handle 1,200W and a coffee maker uses 800W, then the Delta Pro should be configured to charge at no more than 400W (1,200W — 800W)
— Configurable through the EcoFlow app
Tip: AC charging is prioritized over DC when both are connected simultaneously. Never use an extension cord to charge the Delta Pro with unless it’s a heavy-duty one.
If the Delta Pro is used in pass-through UPS (uninterruptible power supply) mode, the internal circuit will turn off its inverter if it detects the AC wall outlet getting overloaded (ie. passing through more than 20A). This means that it could shut off at 1,200W without ever reaching its 3,600W capacity. To use the full 3,600W, disconnect it from the wall and let the battery provide that power.
Note: Using a battery as a UPS (charging and outputting at the same time) could shorten its lifetime.
PROS
– Impressive battery capacity (3,600Wh — 25,000Wh)
— Superfast, configurable charging speeds (200W — 1,800W or up to 6,500W under specific conditions!)
– LiFePO4 technology provides for 10+ years of power
— Up to 2,000 — 3,000 cycles based on my research (I do not believe EcoFlow’s claim of lasting much longer than 6,500 cycles. Hope they prove me wrong 15-20 years from now!)
— Much safer and stable than Lithium-ion NMC
– Large AC inverter with continuous 3,600W (7,200W peak) of output
— Enough to power a typical home for days — or, when used with the EcoFlow (Gas) Smart Generator and/or set of solar panels, virtually forever
— Pure-Sine Wave AC Inverter
— Clean power for sensitive electronics
— Less heat
— Note: Some manufacturers claim to be Pure-Sine when they are actually Modified or Square Waves
– High-quality BMS (Battery Management System) for safety
— Provides built-in overload, overcharge (automatic stop when the device is full), and short-circuit protection
– Expansion/augmentation ecosystem with EF Solar Panels, Double Voltage Hub, Smart Generator, Extra Smart Batteries, Smart Home Panel, wind turbine (not yet available), EV charging station, and Remote Control
– Impressive input and output options, including a NEMA 30A for RV hookup
— Up to 1,600W of solar charging
– Carry handle is strong enough to run a cable lock through for theft deterrence
– Can be used in pass-through UPS mode, though that can shorten the battery’s lifetime
– Beautiful, large, color information display
– Built-in, retractable handle
– Wheels for easier transportation
– Strong Research & Development and Engineering teams who create innovations that Goal Zero, Jackery/Generark, and Bluetti cannot ignore
— Competition hopefully continues to spur better products from all companies
– Beautiful, informative EcoFlow smartphone app with historical data (for Apple iOS and Android)
CONS
– Heaviest power station (99 lbs) I have ever reviewed
— Weight is due to the use of 3,600Wh of LiFePO4 battery cells instead of NMC
— Comparison: Goal Zero, despite using a more heavy-duty, metallic enclosure, has the Yeti 3000X (3,032Wh) weigh at 70lbs, Yeti 6000X (6,071Wh) at 106 lbs
— Difficult to move up stairs, lifting onto truck bed, or pulling across gravel ground — especially with the small wheels
– Plastic enclosure helps shed some weight but is not as heavy-duty as Goal Zero’s Yeti X line
– Bulkier than Goal Zero’s Yeti 3000X and 6000X
— Although I was not able to borrow my friend’s Goal Zero Yeti 6000X for a full comparison review, I took a photo of the Delta Pro next to it for size comparison
– Outputs 3,600W continuously only if powered from its battery and not in a 120V UPS pass-through configuration
– No vehicle integration kit
– Cable to link Delta Pro with additional Smart Batteries is too short, limiting how and where the batteries can be placed
– Car Cigarette Port only accepts 96W of input at 12V
— Goal Zero Yeti X and Jackery Explorer series can take 120W (12V @ 10A)
– Many configuration options are only available through the EcoFlow smartphone app and not from the Delta Pro itself
– Anderson Power Pole (APP) solar part is configured vertically (like Goal Zero, but in reverse)
— Most companies arrange APP horizontally
— Can be remediated by buying an APP extension cable, such as those by iGreely, and re-arranging it
– Manual: Not as detailed and as many helpful tips as Goal Zero’s
– Not an American company
– Not waterproof. Keep it away from water splashes, rain, and pool!
USAGE
CONTINUOUS VS PEAK OUTPUT
It is important to understand the difference between Watts and Watt-Hours. How much power is used or produced is measured in Watts, and how much energy a battery can store is calculated in Watt-Hours. See the “Calculations” section below for more details.
How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).
– AC Inverter: Converts battery (DC) power into AC
— Delta Pro provides 3,600W continuous output with a 7,200W peak
– Peak/Surge (Starting): Nearly every device initially draws extra power to turn on. The highest amount it pulls is the Peak. As long as that number is below 7,200W, it can be STARTED. Because the Delta Pro’s capacity is so high, it is difficult to provide examples for devices that start at over 7,200W. So, to illustrate the concept, I will use the Goal Zero Yeti 1000 Core’s specs (2,400W peak and 1,200W continuous) as examples.
— Turns on OK (PEAK under 2,400W):
— Freezer starts at 400W (peak), runs at 150W once on
— Coffee maker starts at 1,400W (peak), runs at 800W once on
— Will NOT turn on (PEAK over 2,400W):
— Home AC starts at 4,000W (peak), runs at 1,000W once on
Most devices power on at a higher (Peak) wattage than when they are already on (Continuous). Therefore, if its peak exceeds the power station’s max, it may not be able to start
– Continuous Output (Running): Once devices are on, as long as they keep drawing less than 3,600W total, they will stay ON until the battery runs out
— CONTINUES running (under 3,600W)
— 100W TV + 60W laptop = 160W
— COULD STOP running (over 3,600W)
— Temporary overdrawing beyond 3,600W for a few seconds is okay. A quality BMS will protectively shut down the battery if the surge does not end after a while. Regularly going over for a prolonged time can ruin the battery in the long run
— 300W appliance (500W peak) + 1,000W Home AC (4,000W peak) + 800W Coffee maker (1,400W peak) + 1,200W Miter saw (2,400W peak) + 400W appliance = 3,700W. Probably will stay on for a short period
—- Add 1,000W mower (1,400W peak) = 4,700W. Battery will definitely shut down
CALCULATIONS – SIZE & TIME
What size battery should you get? How long will it power your fridge for? How long will it take to recharge? The below calculations can help answer those questions and are rough ESTIMATES as conditions, battery quality, and age can vary.
TIME TO CHARGE BATTERY
– Calc: Hours to charge battery = Battery capacity (Wh) / Input Wattage
— Note: As battery approaches 75% full, the input charge will increasingly be slowed down to prevent overcharging
– AC Wall: 1,800W @ 2 hrs [3,600 Wh / 1,800W]
CHARGE TIME WITH SOLAR
– Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])
— In a perfect lab environment, solar panels charge at the listed wattage
— Expect to only receive 50-75% on a good, sunny day (ie. 75W — 113W for a 150W panel), depending on panel’s age, component quality, and weather
– Two 400W solar panels: as fast as 6 hours [3,600Wh / (2 x 400W x 0.75)]
WATTS USED/PRODUCED
– Calc: Watts used or produced by device = Voltage x Amperage
– Vacuum with 120V @ 9.5A uses 1,140W
– Solar panel with 12V @ 10A can produce up to 120W
IDEAL BATTERY SIZE
– Calc: Battery capacity (Wh) = Watts used by device x Hours needed for / 0.85
— 10-15% of power is lost during power conversion
– 45W car fridge needed for 8 hours: Minimum 424Wh power station (45W x 8 / 0.85)
How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).
TIME BEFORE BATTERY IS EMPTY
– Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device
— 10-15% of power is lost during power conversion
– 60W laptop with 505Wh battery: Up to 7.2 hours (505Wh x 0.85 / 60W)
TIME TO CHARGE DEVICE
– Calc: Hours to charge device = Device’s battery capacity (Wh) / Input Wattage
– 60W laptop with 200Wh battery: Up to 3.4 hrs (200 Wh / 60W)
I did all the research of competing products available and for something thats portable and relatively affordable this is the best product for you to give much needed peace of mind. It was a Time magazine 100 top invention of last year, so that should give you the confidence.
To charge with sun you will need to do some research and spend an approximate additional $1,000 for solar panels, cords, connectors and stands to produce 800W to 1200W for expedited solar charging. YouTube has videos on how to hook everything up. Myself I bought HQST 100 watt panels to mount on vertical poles that can be manually rotated throughout the day to follow the sun for maximum charging experience.
Don’t let World War III catch you off guard with no power, no lights and rotting food in your refrigerator. Eating canned food by candlelight is poor way of life. Your neighbors will envy your home with lights and they have none but be careful they may want to visit and take what you have. You will need to make preparations for this too.
