PURPOSE: To provide a DC power source system capable of supplying a required minimum of load by converting the output of a storage battery to AC power by high efficiency even when the storage battery having small capacity is mounted as an emergency power source. CONSTITUTION: In a DC power source system, a storage battery 7 having small capacity is connected to the output terminal of a DC power source 1 made of a solar cell via a charge/discharge controller 6, a small-capacity inverter 8 having lower rated output than that of a main inverter 2 is connected between the controller 6 and the battery 7, and an emergency plug socket 9 is connected to the output terminal of the inverter 8. |
