PROBLEM TO BE SOLVED: To provide a power conditioner for solar power generation with a protector, capable of preventing application of overvoltage to in-housing load by detecting the connection failure of a receptacle or a connector in advance. SOLUTION: This power conditioner for solar power generation, which is connected to a single-phase three-wire type distribution line 8 using a receptacle or a connector, is provided with unequilibrium dummy load inserted between respective phases of the neutral phase and both sides of AC output of the power conditioner for solar power generation, and an nonequilibrium voltage detector 5 for detecting the nonequilibrium voltage between the neutral phase and respective phases on both sides. |
