solar bank back to grid - is there a switch available?
Hi folks. Usually we think of an automatic transfer switch to go from grid to emergency battery bank when the power fails. I have a system that is mostly self sufficient during the summer but not so much during the winter. Does anyone make a switch that would transfer back to the grid when the battery bank goes too low? I have a manual 240v switch now to support my system but when the batteries dip to a certain level the inverters kick out. I would appreciate any suggestions.
