PROBLEM TO BE SOLVED: To suppress occurrence of reduction in a life of an auxiliary battery as much as possible.SOLUTION: A power system is configured so as to be capable of storing power generated in a photovoltaic power generation device while supplying power to a load. The power system comprises a power converter, auxiliary battery, load power supply battery, and power conversion control unit. The power converter performs power conversion on the power generated in the photovoltaic power generation device, and outputs power after the power conversion. The auxiliary battery is a storage battery connected to the power converter so as to be charged with the output from the power converter, and supplies power required for operation of the power converter. The load power supply battery is a storage battery connected to the power converter so as to be charged with the output from the power converter, and supplies power to the load. The power conversion control unit controls the operation of the power converter. The power conversion control unit controls the operation of the power converter so that the auxiliary battery can be charged when the load power supply battery is being charged. |
