I'm in the process of changing from a cheap PWM to MPPT solar controller because I would like to make use of my four 100 Watt panels (maybe 6 someday) for a house circuit (panel are on my backyard shed). I was looking at the PowMr M60 because it's about a hundred dollars and provides some room for expansion. Anyone have any experience with these? Should I stick with 40amp? What parameters should I look for in one of these? Any brands to stay away from or go toward? Thanks.
