Abstract: Control of supplying power to a storage device is performed based on carbon emission strength or a power rate. A battery center 13 that constitutes a storage device 11 performs radio communication with a gateway 4 and is controlled by the gateway 4. The gateway 4 collects a measured value of power consumed by electric appliances in a home and obtains the carbon emission strength in real time. A solar panel 9 is provided and a battery of the storage device 11 is charged with an output of the solar panel. The battery is also charged with direct current power obtained from power from outside. The power is stored in the storage device 11 based on the carbon emission strength by charging control.

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.
