PROBLEM TO BE SOLVED: To most effectively utilize the electrical power generated by the solar power generation by preventing excessive phase leading operation at the time of controlling a linkage voltage and also prevent fluctuation of the power factor of the operation by the phase leading operation control when a plurality units of the inverters are operated simultaneously. SOLUTION: A linkage voltage based on the linkage operation of the power distribution line 5 is detected, the amount of phase shift to the phase leading operation of the power factor depending on the detected voltage is repeatedly obtained when the detected voltage rises exceeding the preset phase leading operation start voltage, the operation phase of the solar power generation inverter 1 is led depending on the amount of phase shift and the solar power generation inverter 1 is controlled to the phase leading operation in the power factor depending on the detected voltage when the detected voltage is higher than the phase leading operation start voltage. |
