This client wanted to get rid of his electric bill and also have backup power when there was an outage. We installed 12 – SunPower 360W AC modules for a total of 4.32 kW on his roof. That fed into a 8kWh sonnenBatterie for storage. We tied in his generator which will work as his backup to his backup. The first weekend he came to his cabin in VT after we had installed this he said “Hi Bill, I’m at the cabin. Green Mountain power is doing some kind of power installation and power is out everywhere… except at my house. Haha. Everything seems to be working fine with the battery.” He is excited to have energy independence!
