POWER CONTROL DEVICE

摘要

The disclosed device solves the problems that arise when a power conditioner similar to that which is connected to a solar panel is connected to an electricity storage device. DC voltage generated by a solar panel (9) is supplied to a DC-DC converter (51), and is output as a predetermined DC voltage. The voltage output by the converter (51) is supplied to a DC-AC inverter (52). The DC power that the electricity storage device (11) generates is supplied to another DC-DC converter (55). A predetermined DC power from the converter (55) is supplied to another DC-AC inverter (56). The AC power that the inverter (56) outputs is supplied to an AC power system in a household. The converter (55) is configured in a manner so as to have two output voltages. The first output voltage is a standby voltage. The second voltage is a voltage to start the inverter (56) supplying power externally.
