I have a renogy 100 W panel, a bestek 2000 W inverter that a friend gave to me, 2 Deep cycle marine batteries, and I want to get an MPPT controller. This is where I get confused so I have 100 W, I’m using 12 V batteries,  I have a 2000 W inverter,  now what size mppt do I get? 10, 20 or 40 amp?

    your panels do not need a MPPT controller, be happy you can use an inexpensive PWM controller.   After 300-400w, with larger panels in the +200w size MPPT becomes more practical for it's expense

    I will close this discussion... Having the same questions in several areas gets confusing.
