PROBLEM TO BE SOLVED: To provide a power conditioner, including: a power input part connected with a power generation part, a power conversion part for converting DC power input into the power input part into AC power interconnecting to a power system; a control part for controlling a power conversion operation of the power conversion part; and an input current detection part for outputting, into the control part, a detection signal corresponding to an input current of the DC power input into the power input part, the power conditioner being capable of detecting reverse connection of the power generation part even when reverse connection of the power generation part with the power input part causes no power supply from the power generation part to the control part.SOLUTION: By receiving power supply from any predetermined power supply 4 other than a power generation part 2 to operate a control part 6, it can be determined whether or not connection of the power generation part 2 with the power input part 3 is reverse on positive and negative sides even when the power generation part 2 is not properly connected.SELECTED DRAWING: Figure 1 |
