Hello, I recently put together a off grid backup system consisting of a Sungold power 6048 240v all in one inverter and 2 x Sungold 5.12 KW 48v batteries and 10 X 545w Panels installed on my roof. I do not have net metering meter installed, but turn "Solar feed to grid" on my solar inverter will excess solar generated feed my houses current demand during the daytime reducing my overall consumption and just not spin my meter backwards and not convert as much if my demand is lower than the available capacity or do I have to flip over my transfer switches for loads to get powered by solar when my batteries are full and the sun is out?
