Zusammenfassung:	A utility interconnection inverter device (7) includes an inverter circuit (21) that converts DC power generated by a solar panel (3) to AC power by switching a plurality of switching elements, and a controller (39) that controls the plurality of switching elements. Moreover, fans (43, 45) are provided for cooling the plurality of switching elements. Furthermore, a power supply circuit (a terminal 38, a transformer 40, and a power circuit 41) is provided, and supplies power from a control power supply (10) to the controller (39) and the fans (43, 45).
