Hello I have multiple AC500 units operating as battery backup for our main home. We also have a small beach house that we have a 1000KW generator for emergencies during hurricanes using the power company installed Generlink MA23-S. I bought an additional AC500 + B300S to see if I can not have to worry about fuel. Has anybody used this method and has any advice or war stories about it? I have some portable solar panels to recharge the B300S. It is a 2 bedroom with window AC’s. I don’t want everything powered, just the fridge lights fans and of course the TV!
