PROBLEM TO BE SOLVED: To provide a power conditioner capable of efficiently and stably operating a DC load.SOLUTION: A power conditioner comprises: a bidirectional inverter 12 which selectively executes DC/AC conversion to convert DC current output based on power generation from a power generation facility 21 to AC current, or AC/DC conversion to convert AC current from a system 22 to DC current; a system interconnection switch 13 which connects the bidirectional inverter 12 to the system 22; a rectification unit 14 which is connected to the system side of the system interconnection switch 13 and rectifies AC current from the system 22; a DC output switch 16 which feeds the DC current output based on power generation from the power generation facility 21, the DC output of the bidirectional inverter 12, or the rectified output of the rectification unit 14 to a DC load; a storage unit 17 which stores an operation mode in which the DC output or the rectified output is fed to the DC load; and a control unit 18 which controls the system interconnection switch 13 and the DC output switch 16 according to the operation mode and also selects whether to feed the DC output or the rectified output to the DC output switch 16. |
