PROBLEM TO BE SOLVED: To operate the inverters of a plurality of dispersed solar cell power supplies synchronously with a simple construction, by a method wherein one of a plurality of controllers is used as a master controller and the other controllers are used as slave controllers to which common control information is supplied and the inverters are controlled with the common control information. SOLUTION: One of respective controllers 8 is used as a master controller M and the other controllers 8 are used as slave controllers, S respectively. The master controller M is given the command of an linkage operation, etc., by the operation of an operator to form common information in accordance with the command. Then, the master controller M controls the operation of the inverters of respective solar cell power supplies 1 of its own plant and, at the same time, transmits the common information to the respective slave controllers S through cables 11a. The respective slave controllers S control the operations of the inverters 3 of the respective solar cell power supplies 1 of their charges. With this constitution, the inverters 3 of the dispersed solar cell power supplies 1 can be put into same operation states easily. |
