POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power supply system capable of stably supplying power having sufficient electric energy even when power supply by a commercial power supply is stopped by occurrence of a disaster or the like.SOLUTION: A power supply system 100 includes: a first power system for supplying power generated by a solar cell 130 without going through a power storage device 170; and a second power system for inputting power generated by a solar cell 150 to the power storage device 170 without going through a power control unit 140 to supply the power from the power storage device 170. In the case that power supply by a commercial power supply 110 is stopped, power supplied by the second power system is complemented by performing switching so that the power generated by the solar cell 130 is input to the power storage device 170 constituting the second power system.
