Abstract
To solve problems arising when a power conditioner equivalent to that connected to a solar panel is connected to a power storage device.Direct-current power generated by the solar panel 9 is supplied to a DC-DC converter 51 and output as a predetermined direct-current voltage. The output voltage of the converter 51 is supplied to a DC-AC inverter 52. Direct-current power generated by the power storage device 11 is supplied to a DC-DC converter 55. Predetermined direct-current power from the converter 55 is supplied to a DC-AC inverter 56. Alternating-current power output by the inverter 56 is supplied to an alternating-current power system at home. The converter 55 is configured to have two output voltages. The first output voltage is a standby voltage. The second voltage is a voltage at which the inverter 56 starts power supply to outside.
