To provide a power supply system including both of a V2H system and a V2L system.SOLUTION: A power supply system 1 includes a fixed unit 10 and a portable unit 20. The fixed unit includes: an electric circuit 106 which can be interconnected with a commercial power system; a bidirectional converter 103 which can perform interconversion between DC and AC; a general load input/output part 105 which outputs power converted into AC by the bidirectional converter to a power input part of a predetermined facility; and a stationary side connection part 101 which can bidirectionally input and output power to/from another apparatus. The portable unit includes: a portable side connection part 201 which can bidirectionally input and output power through the stationary side connection part; an EV connector 24 which can input and output power to/from a storage battery 30 of an electric automobile in the bidirectional manner; a DC-AC inverter 203 which converts DC into AC; and an output terminal 23 which outputs the power, converted into AC by the DC-AC inverter, to the outside. The portable side connection part can be separably connected to the stationary side connection part.SELECTED DRAWING: Figure 2
