Absolutely amazing charge controller! I connected 12 100 watt panels to a 60 amp MPPT in series/parallel at 48 volts. I see 2.9kWh on cloudy days 4.5-5kWh on sunny days. I've seen up to 1350w from 1200w panels! Don't skimp on the wire and plan your system ritual. Appropriate panels, batteries, equal length wires, low resistance points, good clean connections. And you will be happy. So this is my second experience in different projects, one works 3 months, the other 3 years. Both are perfect and the gauges still read as they did out of the box.
