Review on 🌞 Renogy Commander 40 Amp 12V/24V MPPT Negative Ground Solar Charge Controller Regulator - Compatible with Sealed Lead-Acid, Flooded, Gel Batteries + MT-50 Tracer Meter by Marlo Schlachter

With Renogy you get not only great quality, but also unmatched technical support. My second system is from them and I couldn't be happier. My van is unplugged with a commander, 500 watt panels and 460 amp hours from four 6 volt batteries. They walk you through everything with diagrams and are always available to answer any questions you may have. It's a bit cheaper there, but I wouldn't buy solar products from anyone else.
