Abstract
The converter circuit includes an inverter. The converter circuit receives DC power from a DC power supply (such as a solar cell or a storage battery unit), has the DC power converted into AC power by at least the inverter, and outputs the AC power to a load or a power grid. When acquiring information that two or more types of power curtailment causes have arisen, a control circuit makes the converter circuit limit power output to a maximum degree of power curtailment out of two or more degrees of power curtailment according to specifics of the two or more types of power curtailment causes.
