EPEVER MPPT 40A Solar Charge Controller 12V 24V Auto, 40 amp
EPEVER MPPT 40A Solar Charge Controller 12V 24V Auto, 40 amp Solar Charge Regulator MPPT Automatically Identifying System Voltage, for Lead-Acid Lithium Batteries and Load Timer Setting
Warm tips：
Step: Connect the system in the order of 1.battery–>2. load–>3.PV array, and disconnect the system in the reverse order 3. 2. 1.
Battery must be connected first !!!
Never connect the soalr panel array to the controller Without/Before a Battery.
DO NOT connect any inverter/ wind/Alternator or Charger into the charge controller!
If the remote temperature sensor is not connected to the controller, the default setting for battery charging or discharging temperature is 25 °C without temperature compensation.
The wire size is only for reference. If there is a long distance between the PV array and the controller or between the controller and the battery, larger wires can be used to reduce the voltage drop and improve performance.

Works really well from the box easy to set up and install. Thanks
Get the setup box as well, and it makes a fantastic efficient charge Controller.
Runs 2 x 230 watt panels in series easily and makes over a kilowatt a day
Easy to replace a PWM controller with this MPPT one and much more efficient.

This is my 4th unit MPPT never a problem fit set forget I produce 2.5 kw nice big connections easy read simple fit thank you

So happy I bought this product, it’s taken the guessing out of my solar/ battery system. I replaced a basic one, provided with solar panels as was always guessing what was happening. Now I know for sure. Feels solid to hold, and now installed, looks like a quality product! Shows me how the panels are working & what load is being drawn. Recommend 110%.
Perfect product for a difficult requirement. Appears to be running system as expected

Been fitted now for 1 month swapped for a cheap controller, already seeing better changing results from my 100amp solar panel. Good solid device with strong terminals.

I recommend buying the remote meter, easier to monitor the charging rate etc.
I also bought the battery thermometer, worked fine, not sure how important this is

Had one before. It lasted 12 months. And then died. I experimented with a few cheaper options (some were death traps) and realised for sub strong money, these are way ahead of the competitors in this price bracket. Maybe I’ll re review in 12 months?

This seems a well made piece of kit, very easy to install and set up. It as been working on my narrow boat for a couple of months now and all seems well.
The net result is that my stay in a caravan for a six month build has turned into 3 years of no Electricity, water or sewage.
After a while I started to look at solar power to enable me to live without a generator running 16 hours a day.
Through a process of trial and error I have wound up with 3 ex-solar farm panels, 8 100Ah lead acid batteries a Honda 2KvA Generator and this solar charge controller. It is easy to set up and provides good monitoring of both the Solar PV output and the battery state and on bright sunny days provides a steady 40A charge current. It also highlights the weakness of solar power if, like me, you are off grid. From the end of September until the end of April there is simply not enough energy from the solar to keep the batteries charged despite the undoubted efficiency of this controller.
The first one of these showed that it really is only splash proof , the electronics were destroyed by water getting in round the LCD display, I had the lid of the box that it is stored in open for a few minutes whilst I checked a connection in a rain storm. It did not stop working completely but became very erratic and it was only when I opened the box up in desperation to find out why it was so erratic that I discovered the water damage.
In my installation, this charger, my generator fed mains charger and my inverter all live in a plastic garden storage box with a two 12v computer cooling fans, one at each end of the box to keep the whole installation cool as the solar charger becomes quite hot when running flat out. Ventilation for this unit is essential to keep the operating temperature within acceptable limits. It’s hard to know just how much more efficient a MPPT controller is than a cheaper PWM controller in real world situations. Having used PWMs before on a boat I think on balance that it probably worth the extra cost, but is not a game changer in comparison with other elements of a solar setup
