Abstract:
The present invention provides a power conditioner that, without requiring an additional structure, is able to detect the attachment state of a current sensor attached to an electrical wire that connects an electric power system and the power conditioner. This power conditioner (10) has: a power conversion device (14) that can convert electric power outputted by an electrical storage device (3) to a prescribed DC power; an inverter unit (12) that can convert DC power to AC power and output the AC power; a first current sensor (16) for detecting output current of the inverter unit (12); and an assessment unit (22) that assesses the attachment state of a second current sensor (8) on the basis of a first current value detected by the first current sensor (16), and a second current value detected by the second current sensor (8), which is attached to a first electrical wire (4A).
