An AC inverter in a vehicle operates using a 24V input when a vehicle powertrain is in a parked/idling state. A first 12V battery is connected with a first bus segment. A second 12V battery is connected with a second bus segment. A switch module selectably interconnects the first and second bus segments. In a nominal 12V state, the batteries are connected in parallel from the bus segments to ground. In a dual voltage state, the batteries are connected in series so the first bus segment is at 12V and the second bus segment is at 24V. A first alternator driven by the powertrain provides a regulated voltage to the second bus segment, wherein the regulated voltage corresponds to 12V when the switch module is in the nominal state and corresponds to 24V when the switch module is in the dual voltage state.
