SOLAR POWER GENERATING EQUIPMENT

PROBLEM TO BE SOLVED: To provide solar power generating equipment operable of operating with a battery and a solar battery or with only a solar battery without troublesome changeover. SOLUTION: The equipment is provided with a battery 3 connected in parallel with the solar battery 1 through a charging and discharging means 30, a power converter 4 which interconnects the output power of the solar battery with another AC power source 8, a maximum power follow-up control means 21 which changes operation command in the increasing direction of the output of the solar battery, and DC constant voltage control means 22, 23, 24 for controlling the voltage of the solar battery to a constant, means 25, 29 for performing control by power commands from the outside, and a change-over switch 26. The voltage of the battery is set so smaller than a DC constant voltage of the solar battery, and discharging of the battery is prevented when the voltage of the battery is lower than the voltage of the solar battery. Maximum power follow-up control or DC constant voltage control of the solar battery is performed when power is not supplied from the battery. Control by the power commands from the outside is performed when power is supplied from the battery.
