question???<br />I don't know much about electric....I have 2 batteries, a switch that turns ...1 2 all off...I have a panel with 120 v circuit in the cabin with a outlet, hot water heater, refigarater....this is not working ( the boat is in my yard )does this only work with shore line power? does that mean I can't use it until I am plug in? ...if I am on the water, I can't use the outlet for anything like a T.V.?<br />can someone explain ???<br />thanks<br />Laurie<br />
