I gave this inverter a super test from my 240amp battery which had been powered from solar panels. I managed to run a Tefal actifryer to cook chips while the kids were watching the TV and also we were charging mobiles… all was good. Although I wouldn’t recommend using a actifryer on a regular basis as it uses lots of power.
Love this unit. Really high quality build and feel but was bought solely to power a Nespresso machine in my motorhome and it wouldn’t work. Replaced with a chinese pure sine wave unit which does power the machine

This product has loads of fantastic reviews.
The install and the setting up of remote switch was really easy.
I have had this unit for little over a year and it’s alarming out saying 9999w overload, I have only used this a handful of times using my dremel.

Looks good and oozes quality.
Has been invaluable using various 240V tools running off a car battery in a garage with no mains power.
Remote control rated 1 star as it does not have one (or I don’t remember it and have never used it).

Looks good but only just got it so how can I review it yet.
Very happy with it. Bought it to put in my work van to run a microwave and kettle. Never let me down yet 5 weeks in. Remote is a good idea so I can isolate when not need. Quality seems very good and came with everything to install it. Highly recommended
Added inside my boat 2months ago, for charging phones tablets and a small TV with amplified aerial. This unit works well and has given me no problems. I was a little concerned about the TV working, but it is a perfect picture and sound.
The wired remote is a very good idea, you can turn it off where you can easily get access, rather than having to switch off on the body of the unit (mine is low down behind a step) .
Package arrived following day and well wrapped. I would buy agai

Got this for the carvan best thing I got as well as a car battery
Well what can I say bought this unit worked great I managed to burnout one side of the output so it stopped working. I contacted
K KRIGER and said what I had done. Their customer service was excellent said if I return the item and they would see what they could do. I sent it on Saturday and got a brand new one on Wednesday no charge. What excellent service thank you K KRIGER you have a very happy custome

We need to run our 1100W nespresso machine or our 1kw kettle in the wilds. This model copes with either (not both together!). The fitting kit includes terminated cables of very high quality and a 150A fuse and is ready to attach to the battery. I plugged a mains extension lead into the inverter mounted the brilliant remote control unit on a blank faced box next to it, with the cable supplied. On no load the inverter drew 300mA – the remote ‘off’ reduces standby to about 35mA (measured using the battery BMS Bluetooth App) – no need to keep going to the battery box!
I boiled my first mug of tea using 2% of our102Ah battery capacity (BMS App again), and the solar panel replaced that in about an hour.

It’s not often I write reviews, but to be honest, this inverter seems to be very well made, works for those little annoyances. We ran out of gas (just once) of course it was a Sunday where nothing was open, so invested in this inverter just to boil a kettle, or to run a hair dryer if we needed to go off grid.
It works like a charm, The install was easy, the hard part was were to put it.
Love the idea of the remote to switch on and off. there is a on/off switch at the rear of the unit, the switch has to be on for the remote to work.
Brill little gadget. Glad I purchased one.

Very well made and looks very good. Before purchasing make sure the version will supply the right amperage etc to your appliance. This was purchased to run a handheld carpet cleaner and it works a treat. Have also used it at a craft show where I ran a 3d printer to promote product sales. Feels and looks quality and has very good reviews across many sites.
I bought this as a 240v power source to connect directly to shutter motors to override key switches. I tested it with a 1850 Watt hair dryer. It powerd the dryer faultlessly. The unit is well built and feels the part.
The only thing I would change is to allow the 12v leads that connect to the 12v posts on the rear of the unit to be able to be connected at any angle. The leads only connect one way which could make it awkward for some applications.

Brilliant piece of kit. Used up the allotment to charge batteries and boil a small kettle. Very well made with clear instructions.
To be used in a campervan. Awaiting leisure battery and connectors to test out. Will need some bolts to go on battery.
Used to provide 220v on a fully off grid boat. Runs everything – fridge freezer, smart TV, home-fi mobile broadband. Needed to substitute power cables to reach 400Ah battery bank as supplied weren’t long enough but that’s due to my set up, not the inverter. So far has been faultless. All round, I’m pretty impressed.

I have had the inverter and remote for around a month now. Great for charging laptop etc and making lots of tea! I had a little problem with the cable to the remote and Jim replaced it immediately. All works lovely and i am very happy!
As soon as I opened the box, it felt and looked right, came with nice Chunky cable and a decent quality fuse. It’s not a pure sine, and I can live with that. It’s runs a fridge and freezer 24/7 and we can use a 1000w kettle and a 700w pop up toaster with the fridge and freezer at the same time. We did use the remote control, but have put back in the box again, due to the white goods being on all the time, the lights on the remote were a unnecessary drain on the battery. Once thing I’d change, is to be able to switch off the front led button lights on the unit. It’s been running a month now, and I’m very happy with it.

This product seems well made. It’s far more efficient than the 1000w Chinese inverter that blew up last week. Boils 400ml of water in a 650w kettle in about 2 minutes. The old one took 5 to 10 minutes. This one is a lot easier on the batteries too.

Only fitted today but was so simple to fit. Came with a 150amp online fuse, cables with loop terminals for easy connection to battery. Bought it to power a small fridge in a van conversion, fridge worked a treat, didn’t even stress the inverter.
I think if I had to have one whinge it would be that the inline fuse is in the middle whereas I would have preferred it closer to the battery connection and the cables could have done with being a tad longer. But that is only due to where I wanted to site the inverter. Where it is now is fine so cables are long enough
For the money it is great, and with 3 years warranty you can’t go wrong!
This inverter will run my microwave, hoover, toaster, low wattage, kettle (not all at same time!) no problem on my boat. would recommend
We tried a Cheaper version and failed.
This product does what it says on the box
Working great in my Motorhome.
Just a solid piece of kit. Linked to my solar charging system and works perfectly. The remote is handy as the unit is tucked away.
For the price you cannot beat it.

Great piece of kit, does what it should, seems to be a solid item, remote is well designed and very tidy when installed in a panel, looks the bis.
Very pleased. Normally use Sterling inverters so will have to see how it performs in comparison, but much cheaper.

This is in my garage/workshop for running tools and does a good job off 2x 12v 110a leisure batteries.
Good build quality and works well but this is my second one – the first gave up and I’m not sure why. I never used too high a wattage tool on it or abused it but the maker replaced it no problem
Remote control looks as though it should be able to display the same information as on the panel of the unit but despite the network type cable it is just an on off switch. Unit is very well built. High quality power cable connectors. Needs fitted properly but high quality.

Well what to say o my god did not think it would be this good for the price well made accessory supplied excellent parts
Just what we were after for our VW transporter to use with a low voltage heater and kettle.
Only issue was the cables supplied are rather short so I had to purchase longer ones separately

I have this unit running a tyre machine in a mobile tyre unit with a 1.1kw motor , works perfectly, amazing company to deal with 100%
Brilliant product and easy to fit mine runs a microwave in my work van so I can have healthy hot meals at dinner time at work
Can’t rate this product high enough, I made the mistake of ordering as inverter off eBay supposedly 500/1000w only fit for bin. So ordered this one it’s brilliant!! Has output level screen ( watts or volts) is running a 240 fridge in van . Remote on off switch is great too! Can’t comment on reliability but comes with 3 yr warranty so should be ok.

I used to work in Telecoms so were used to seeing Inverters. This is a solid product easy to install and setup. Save time and buy, mine was for three 120w solar panels

There is nothing not to like it’s robust it comes with all the cables and the remote is fantastic it means I can hide the inverter and not have to worry about getting to it.

Unlike the vast majority of inverters you see on auction sites this one can actually handle the advertised power. I just returned a supposed1500w/3000w inverter that had a single 40 amp fuse! This one is excellent and the remote on/off switch is truly useful. Saves me getting out of the camper every time I need some juice. Cannot recommend highly enough. 10 stars.

Soon as I opened the box I thought this is a quality product. I looked at 4 different inverters this one stands out in my opinion. It looks well made. Cables look good quality with eyes for battery connection rather than crocodile clips. The positive cable has a built in fuse. Very important for me, the instruction leaflet provided is comprehensive and useful (not a couple of small pages with little info). It has mounting brackets for mounting rather than portable. Screen is clear. Remote switch is useful.
As to performance. I have only tried it briefly everything appeared to work as advertised. The fan did not come on during short test. This is a bonus other fans ran constantly even with a small load and I think would be an irritation.
Its for use in a campervan with a leisure battery. I’ve given it top marks based on my first impressions, should I discover negatives during more regular use I can update my feedback.
Works great. Feels quality bit of kit
Edit. I’ve knocked it back to 4 stars because after our first major trip out with it, the remote stopped working and it came up with an overload error that would not clear. I contacted Krieger (in the USA) and he sent me instructions on how to clear the error. Would not work so I had to ship it to somewhere in the UK for a replacement. Took a couple of weeks but I got a new replacement that worked fine (I had to chase them up a couple of times)
I’ve now updated to a 2000w pure sine wave as my wife’s hair dryer kept tripping this unit although it only draws 800w max.
I can’t fault their USA support but the unit itself just seems a bit unreliable.
Instruction were really straightforward. Product plugged in and is supplied by 2 * 110ah leisure batteries. Supplies the caravan with all the power I need for all the accessories – water heater, fridge, lights, sockets, etc, etc
Remote control mounted at the door way of the caravan so it activates the inverter instantly.
Really good bit of kit with no hassle.

Having burnt thru some cheaper 1500w continuous inverters I figured it was time to upgrade to something a bit more expensive and hopefully more reliable.
Not disappointed. It was obvious it was far better built by the fact it weighed 3 times more than its predecessors!
Larger footprint too, but with a 3 year warranty, and heavy use, I wanted peace of mind.
Easy install (do make sure you follow the instructions before connecting to a battery or you might just end up with a brick!). Make sure unit is off, by the switch, don’t even plug in the remote. Make sure you have nothing plugged in.
A sudden surge can fry electronics. Install a suitable in line fuse as well and make your final connection using it.
For reference I am running 1000w oven at 240v from 3 x 200mah agm cells. I get hours of use with it.
Faultless.
I bought this to fit in our boat to power a small kettle and the laptop. It is well made, easy to fit and the cables, fittings and instructions are top quality, better than some more expensive inverters I have looked at. I only fitted it yesterday and tried our 900w kettle and it worked fine. The cooling fan kicked in and it worked as it should. I like the display, at a touch of the button you can see exactly the wattage you are drawing.
Recommended.
Excellent Recommended by a neighbour, and it works a treat – I now have mains electric in my garage for lighting, power tools, bicycle charging and CCTV. I like the cable remote turn-on option, silent running when using mains lighting (and low current devices), the twin USB ports, design, and the parts/instructions supplied.

Turned up on time. Packaging was very good.
The inverter itself looks slick, and the remote control is a great feature.
I brought this product to go with my 12v battery and solar panel set up for going off grid when we go camping.

So far so good. Running microwave, PS4, tv, Dolby surround system and Dyson fan in my truck. The product is surge protected, has great warranty and is very well made. Simple to install. Very happy. HGV drivers of your looking for one this is the one.

Installed in a camper van but not yet used so cant comment on its performance but build quality looks good and the instructions are very clear. So far so good. It will probably be months before i get to use this in the current climet.

Excellent bit of kit up to 2000W, though it will not run a 2200 W hairdryer at all, not sure about 4000W peak output claims, Remote control ok but does not show any info re battery condition. with hindsight i would get the 3000W unit.
I had to return this unfortunately, it seems to be a well made unit with plenty of features and to be fair, for the money it does seem good value. I found that it couldnt cope well with some devices even though the draw was well under its capacity. Ive seen a few others with similar reviews where voltage drop causes issues, which I experienced also. However, still 4 stars as for lower power its packed with features. I ended up getting a similar wattage inverter that cost much more, it has far less features but takes the load with no issues. Still a good unit but may be worth going for the higher power products if in doubt.
Compact, well constructed and supplied with decent cables and fuse.
Appears to be a well-made inverter. Nice heavy power cables with 150 Amp inline fuse. Reasonably quiet when in operation and the fan is running.
Did some bench testing to monitor current draw across a range of resistive loads.
DC current draw powered but in ‘Standby’ 0.034 Amps (34mA).
Current draw when energized, but no load (quiescence) 0.5Amps
22 Watt Resistive load: Input: 2.1 Amps @ 12.2 Volts. Efficiency 86%.
340 Watt Resistive load: Input 32.5 Amps @ 11.5 Volts. Efficiency 91%.
632 Watt Resistive load: Input 64.8 Amps @ 10.6 Volts Efficiency 92%.
Obviously reactive loads (inductive or capacitive) will be less efficient, but pretty good
across a broad range. As for longevity, only time will tell 😉
Well made and does what I need in my Motorhome, runs the microwave and coffee machine whilst staying on Aires with no hookup. Happy days. Have to update, whilst it’s great for microwave, vacuum cleaner and fan it won’t work with my new Nespresso coffee machine. I suspect the electronic on the coffee machine don’t like anything other than pure sine wave and not modified sine wave, as the same machine works in our house of off the solar inverter which is pure sine wave but cost a lot more money, 800.
Very good robust looking inverter, you can pay much more for a high output inverter and it would look cheap, but this one just looked very high end in build quality. Was surprised it was made in China, after reading the manual, the name sounded German, hence why I purchased it, and was not dissapointed in the quality.

There were so many options for inverters but I settled on this after ploughing through lots and lots of reviews of several. I am impressed with the quality of this unit. The remote is a nice touch and the supplied cables are decent quality and amperage. I did swap out the fuse block with another because it seemed to use a non standard size fuse so it would be harder to carry a spare.
Good bit of a kit, bought a cheap Chinese one which was useless. This one works brilliantly. Plugged a 1000w heater in and works just fine, for instantly heating the car. Haven’t tested over a long period yet but impressed so far. The leads are too short and I managed to fit cramp on ring terminals to some jump leads to use but I don’t recommend this unless you know what your doing.

I’ve had it on test bench, looking good so far. Of 1 12v battery it will run small compressor fridge and drill all 240 volt. This inverter is the real deal but like all inverter,s read the instructions. I will be running it off 3x 110ah batteries with a 240 volt compressor fridge fulltime. Looks like this is more than upto the job. I’ll report back in a few months.
Great quality built inverter. Built to high standard, comes with heavy duty cables and fuse, remote control, I’m running a 3 battery bank of 300amps works great highly recommend. Not like many low budget inverters with thin wiring, well pleased with the whole thing , and it arrived the very next day.
All tried and tested and I must say I am impressed with this bit of kit, looks and feels well built and with all the cables and fitting supplied (apart from battery’s) it can be used straight from the box, the remote control that comes with the 1500w is a well built addition to the inverter and does not have a cheap feel to it, being able to control the inverter from the kitchen area of my camper alone is worth the extra money, this runs all the equipment I need it to run the most power hungry thing I use is 800w so not really tried anything that needs more but I’m very impressed with it and it’ll do me fine, really pleased I chose this one, no regrets and I highly recommend i
Powers everything as long as you stay within the wattage stated and you use a good deep cycle battery ie 95ah that seems ok for my requirements..only thing it wont run is my small fridge/freezer, tries but after 30secs fridge cuts out not the inverter watts showed 570w as it was trying…may need a pure sine wave?
