POWER CONDITIONER SYSTEM AND POWER-STORAGE POWER CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide a power conditioner system and a power-storage power conditioner for feeding power to an important load without requiring time and labor for the replacement of important loads when the grid power is cut off.SOLUTION: Provided is a power conditioner system comprising a power-generation power conditioner 30 for connecting a power generation facility 11 to a grid 12 and a power-storage power conditioner 50 for connecting a power storage facility 13 to the grid 12. The power-generation power conditioner 30 is provided with a self-sustained output switch 34 for outputting power based on power generation by the power generation facility 11 separately from power feeding to the grid 12. The power-storage power conditioner 50 is provided with a self-sustained output switch 54 for outputting AC power based on power storage by the power storage facility 13 separately from power feeding to the grid 12. At least one of the AC power based on output power from the self-sustained output switch 34, the AC power based on output power from the self-sustained output switch 54, and the grid power of the grid 12 is fed to a self-sustained output system 62 to which a prescribed load is connected.
