EPEVERMPPT Solar Charge Controller 40A 12V 24V Auto + WiFi Adapter Remote Control via APP + Temp Sensor Cable Solar Panels Charger for Lead-Acid LiFePO4 Lithium Battery (Tacer4210AN+WiFi+RTS)

I have used 2 of these on different systems. Seems to be a lot more stable that a Renogy. Very straight forward to install. Make sure you always connect solar last and disconnect solar first if servicing.

This was as well as could be expected for cheap Chinese manufacturing. A little cryptic on how to set up battery type and when the load is to be on or off. Overall, it worked well for deep cycle lead acid flood batteries in parallel at 12V with four 100W panels in series for 80V.

This is a very nice and quality controller. It does come with the remote readout unit, but the extension wires are too short for my use. I wanted to locate the remote readout unit in the other room, but the wires wouldn't go that far, so I had to locate it not too far from the controller itself.There are so many to choose from, but I recommend this unit.

I’m able to access my solar controller anywhere I’m at

This is an amazing upgrade to the one I had!VERY easy to read instructions and easy install! Have had for a month and it’s working flawlessly! bought a cat 5 cable to extend the display to the inside

Don’t know how good the controller is, but the WiFi connection doesn’t work. I spent two weeks after hours to try to connect this crap. I downloaded and erased several different apps hoping I don’t know what I am doing. But this crap it’s not working!Local connection yes. Put it on the cloud with remote access no way!One star because you can’t give 0!

Looks nice and built good but have not had time to install it yet

I bought the 20 amp model, hooked up to 2 - 100 watt panels and 2 - 100ah, 12 volt batteries to run the 12 volt system on my off grid camper, and has worked flawlessly for the past 2 months. So far so good.
