Abstract: The power conversion system includes an inverter circuit. The inverter circuit performs a grid-connected operation and an independent operation. When performing the independent operation, the inverter circuit may output, via a terminal, AC power converted to a load disconnected from a power grid. When the inverter circuit performs the independent operation, a control unit controls, when operating in a first mode, the power conversion system in a first time range such that an AC voltage is applied to the terminal, and controls, when operating in a second mode, the power conversion system in a second time range different from the first time range. The second mode includes control of stopping an operation of having the AC voltage applied to the terminal.
