In order for a power conditioner to start up appropriately, additional components external to the power conditioner, such as an AC load circuit and a circuit switching device, are required for startup determination. Furthermore, a discharge resistor must be provided separately for a DC unit. To solve these problems, this power conditioner is equipped with: a main circuit unit, which is equipped with an inverter unit that converts DC power from a solar cell to AC power; and a startup determination processing unit, which is equipped with a switching pulse generation unit that sends a switching command to the inverter unit of the main circuit unit, and a comparison unit that compares a predetermined minimum possible operating voltage value and the DC voltage value when power is consumed by the inverter unit on the basis of the switching command transmitted by the switching pulse generation unit. |
