PROBLEM TO BE SOLVED: To obtain a power conditioner which is not broken even when miswiring of an AC wire occurs.SOLUTION: A power conditioner 100 of an embodiment includes: a DC terminal block 10 comprising two terminals of a positive electrode and a negative electrode for connecting a solar cell; an internal circuit 20 which is connected to one of the terminals, converts a direct current inputted from the DC terminal block into an alternating current, and outputs it; a diode 11 which is connected to the internal circuit 20 so that a forward current flows from the terminal of the negative electrode when the voltage of the negative electrode becomes higher than the voltage of the positive electrode; and disconnection means 30 which cuts off electrical connection between the other of the terminals and the internal circuit 20 when the forward current flows. |
