A power conversion apparatus includes a power converter, a voltage detector, a determiner, and a drive controller. The power converter is configured to convert DC power input from an electric generation apparatus into AC power. The voltage detector is configured to detect a DC voltage input into the power converter. The determiner is configured to determine an output power command or an output current command based on whether the output power command or the output current command has a first level that is correlated in advance with a second level of the DC voltage detected by the voltage detector. The drive controller is configured to control the power converter based on the output power command or the output current command determined by the determiner.
