🌞 Efficient EPEVER 40A MPPT Solar Charge Controller for 100V PV Max Input: LiFePo4 Battery Charger with MT50 Remote Meter & Temperature Sensor Tracer4210AN Review

Works very well at 600 watts. Charges 6 (12V, 100Ah) backup batteries set to 24V in 3 banks. I'm happy with it so far. Has been working for 6-7 months now.

This charge controller has been working without problems for over a year. We have 4 batteries of 6 volts. true sine converter and 2 x 150w panels to power our 24x24 loft cabin.

Reliability at the same time. The instructions are numerous and helpful. There was no problem connecting a 12V LiFePo4 battery pack to the 300W solar panels connected in series. Runs like a champ. There is a slight change in charge cycle voltage, but we knew it was included in this project. Do yourself a favor and get a remote WiFi monitoring add-on. It allows you to use a laptop to set all the parameters. Hopefully it will last us years.

Charger works fine, LCD panel stopped working 5 months after purchase. Emailed SolarEpic twice but no response. I think I need to get Revain. Update: Haven't solved this problem yet. At the moment I don't think I will order SolarEpic products. They sell quickly but don't respond to warranty issues. Also, Revain has yet to step in and help resolve this issue. The whole deal with Solarepic was far from satisfactory.

LiFePo is NOT supported without buying additional junk and downloading caveman software which looks like it's from the Windows 3.1 era. False advertising always gets a low score from me until people learn how to write an accurate product description that isn't misleading. The instruction manual is also a hash, but at least not a full-fledged Chinlish. Another warning, some people here say that the cables to buy are not properly connected. I haven't gotten that far yet.

This MPPT charge controller seems to work quite well. I am running 250w solar panels with two 100ah deep cycle AGM batteries. It's day three and even on cloudy days (here in northwest Washington state) my batteries have never dropped below 12.6. And I'm looking at a 24-inch smart TV with 50-watt speakers, a small LED backlight, and a small fan. I leave a fan on all night to help me sleep. I am very happy that I bought this charge controller and I am happy to give it 5 stars.

later I bought one of these for the solar installation in my cab above the motorhome. It was basically plug and play with a lead acid battery and I had no problems with it this fall. When I first connected it I had the polarity of the solar panels wrong. The device didn't give any useful error message or anything, it just didn't show any solar power but it basically protected itself and I was able to find the source of the problem. It has a nice timer feature that lets you automatically run a…

You should know that 40a is what a controller is, I also think it's max 720 watts, read the instructions with it, I have 600 watts on 3 x 200 panels, I draw 2 kilowatts a day, winter spring, fl. I have 6-6 volts 215 amps. Sam's Club Hour Batteries. At 10 o'clock I am fully charged with 14.5 volts. This controller is so reliable after 3 months of use that I exceeded the advertised 520w or so because the manual says it can exceed those limits and if the amps are bigger it will just lose power…

Excellent charge controller, information display is very useful, kWh counter included. I can't speak for the accuracy of the information provided, judging by my cheap multimeter the voltage and current readings seem correct and therefore the kWh meter should be fine too. It seems to correctly track the maximum power point. You can choose between flooded, sealed and gel batteries with an integrated user interface. If you need to provide your own battery parameters you will need an additional…
