ABSTRACT:
A battery powered inverter power supply for recreational vehicle refrigeration units or the like which is adapted to operate in a DC mode wherein power is supplied to the inverter and refrigeration unit from a vehicle battery, and in an AC mode wherein power is supplied to the refrigeration unit from a source of normal household power. A cold control circuit is responsive to a thermostatic sensor within the refrigerated enclosure to apply battery power to the inverter power supply only when the supply is operating in the DC mode and cooling is required. A battery charger is operable during the AC mode to automatically recharge the vehicle battery.
