Abstract
The present invention prevents an increase in an overvoltage and increases an optimum operating voltage of a power inverter. A photovoltaic power generation device is provided with a solar cell device,, a power inverter,for inverting output from the solar cell device,into AC power, a current path circuit,connected in parallel between the solar cell device,and the power inverter,, and a current detection circuit,for detecting a current feeding back to the solar cell device,. When a current detected by the current detection circuit,reaches beyond a predetermined current value, the current path circuit,is cut off.
