Kind Code:
A1
Abstract:
The present invention eliminates the use of an overcharge protection circuit in a storage battery. An electricity storage device 30 has a storage battery having a predetermined charge termination voltage equal to or less than an overcharge protection voltage, said predetermined charge termination voltage being the maximum chargeable voltage. A wind power generation device 10 and a solar power generation device 20 output DC voltage to a DC bus 100 only when the voltage of the DC bus 100 is less than the charge termination voltage of the storage battery.
