PROBLEM TO BE SOLVED: To obtain a power supply system capable of autonomous operation without adding an autonomous operation switcher to an existing house, in order to simplify installation work and reduce an occupied space in the house.SOLUTION: A power supply system includes: a system 1; a power generation unit 8; a storage battery 17; an autonomous operation switcher 15 that switches power transmission/reception to/from an indoor load 10 and is connected to the system 1 and indoor load 10 through a house distribution board 9 to which the system 1 and the indoor load 10 are connected; a power conversion device 11 that converts DC power from the storage battery 17 for DC power storage to AC power to output the AC power to the indoor load 10, and converts AC power from the autonomous operation switcher 15 to DC power to charge the storage battery with the DC power; a control circuit 16 that controls output power of the power conversion device 11 and controls switching operation of the autonomous operation switcher 15; and a frame that accommodates the power conversion device 11, the autonomous operation switcher 15, and the control circuit 16.SELECTED DRAWING: Figure 1 |
