This electricity storage system comprises an electricity storage cell, a device for electric power conversion, and an electricity storage system controller. The electricity storage system controller charges the electricity storage cell using electric power during a specific time period at night, and regulates an electric discharge from the electricity storage cell in the daytime. During standby in which the electricity storage cell is not being charged or discharged, and when the electricity storage cell is being charged, electric power is supplied from the system side. When the electricity storage cell is being discharged, electric power is supplied from the electricity storage cell side without passing through the device for electric power conversion, and before the electricity storage cell over discharges, the electricity storage system controller switches to a state in which electric power is supplied from the system, and discharging of the electricity storage cell is stopped.
