摘要： A device for operating inverters according to the present invention can operate a plurality of inverters for converting DC output from a DC source such as a solar cell to AC output efficiently without relying on a particular inverter. The plurality of inverters are connected to the DC source through switches. DC output from a DC source is measured by a measuring device to determine the number of inverters to be operated on a basis of the output result from the measuring device. The inverters to be added or cut off are determined among the plurality of inverters at random on a basis of the random number and switches of the determined inverters are turned ON or OFF in order to select inverters to be operated.

摘要： A power-supply system involving system interconnection includes a plurality of AC modules, each of which includes a solar cell module and an inverter unit which outputs a single-phase alternating current. The AC modules are connected to the single-phase three-wire distribution line such that the number of AC modules connected to the outer conductor R is the same as the number of AC modules connected to the outer conductor T. Each AC module has three junction pole pieces. Adjacent AC modules are connected to each other via a connecting cable connected to the junction pole pieces. Each AC module has a change-over circuit so as to be selectively connected to one of the outer conductors R or T. The power-supply system further includes an independent operation control device for independently operating the AC modules when the connection between the AC modules and the commercial electric power system is cut.
