PROBLEM TO BE SOLVED: To provide a charge/discharge system capable of charging a storage battery of an electric vehicle when performing maintenance of a power conditioner for an electric vehicle.SOLUTION: A charge/discharge system comprises a power conditioner for an electric vehicle 120 that supplies AC power supplied from power distribution panels 20, 30 connected to a system power supply E and a photovoltaic power generation system 10 to a storage battery in an electric vehicle C, or converts DC voltage output from the storage battery to AC power to supply the AC power to the power distribution panels 20, 30. The charge/discharge system comprises: a water-proof grounding outlet 121 to which AC power is supplied from the power distribution panels 20, 30; and a photovoltaic power generation system 15 connected to the power distribution panels 20, 30. Power generated by the photovoltaic power generation system 15 can be supplied only to the power conditioner for an electric vehicle 120 by changing over a changeover switch. |
