Here is a little off grid system we built for a remote cabin outside of Prague, OK. It consists of 4 X 280 Watt Canadian Solar modules, 4 X 380 AH AGM batteries, a 2kW Victron inverter, charge controller, DC:DC, bluetooth and BMS monitoring, all connected through a Midnite Solar DC source center. Let us know what you think. Call today for a free analysis. You might be surprised to learn what Solar can do for you!
