PROBLEM TO BE SOLVED: To provide a controller for a power conditioner that can effectively utilize generated electric power of a power generator even if a power failure occurs to a system power source.SOLUTION: A controller for a power conditioner that is connected to a storage battery and configured to perform an autonomous operation if a power failure occurs to a system comprises: other power conditioners connected to a power generator and configured to perform linkage operation with the power conditioner; voltage input means connecting the power conditioner to a load and the system and receiving input of a voltage value of an AC power line; voltage control means of controlling a voltage, output by a bidirectional electric power converter converting electric power bidirectionally between the AC power line and storage battery based upon the voltage value; and power failure detection means of detecting a power failure occurring to the system. When the power failure occurring to the system is detected, voltage control means instructs the bidirectional electric power converter to output a predetermined voltage to the AC power line.SELECTED DRAWING: Figure 3 |
