My problem is a bit different. I have a healthy amount of solar but don't want to buy batteries (even in truck form). The solar needs AC from the mains for some reason. Is there some way to hookup a small generator to make the solar happy and then use the solar for power? (Yes, I'd have to disconnect everything from the grid.) Let's assume that I don't try to use too much power. Will the solar be damaged if I don't use enough?
