I recently purchased a 1995 Liberty. I had to store it outside until finding indoor storage with 50 amp service. My question is: should I plug into shore power, turn everything off at the panel except for the battery chargers and leave the inverters on or off? Will turning the inverters off prevent the batteries from staying charged. The starter batteries have a charger running thru a 120 volt outlet in the engine compartment so if the inverter is off would that prevent the charger from operating?
