EPEVER MPPT Solar Charge Controller 30A 12V 24V Auto Max PV 100V Solar Panels Common Negative Ground Upgraded Regulator, LED & LCD & 5 Keys for Gel Sealed Flooded Lithium User Types (XTRA3210N)

This XTRA 3210AN was my second Epever charge controller, which I paired with my first LiFePo battery. I had worried about the firmware update process, since I use Macs, and the software was for Windows. No sweat. I borrowed a Windows and the seller patiently guided me through every step of firmware update process. They answered each question I posed within, at most, a few hours. After I'd updated the XTRA3210, they even helped me update my previous Epever, a Tracer 4210, so that I'll be ready to replace the AGM battery it controls with a LiFePo when the time comes.

I needed a quality solar charge controller I could trust out in the middle of a forest where it functions for months without being there. With the FOB WIFI added, I am able to remotely monitor the solar system.Well worth the money.

Very good controller.Till now used simpler ones, this one gave me at least 20% more Ampers.Simple configuration, bought the wifi adapter, and can see view and configure though the phone app.

This does a good job of converting solar panel power to battery power. The manual is confusing though. It has 2 controllers in it. The Lithium setting is GEL . This is because GEL does not use equalize.

good quality
