Summary:PURPOSE: To supply electric power efficiently to an independent light operation load by performing a linked operation utilizing to a maximum degree the generated power from the arrays of solar cells by using all the inverters at the normal time of the power system and permitting the operation of an inverter with a high efficiency during power interruption in the power system. CONSTITUTION: At the time of a normal state of a power system, four inverters 9a to 9d are all connected in parallel and the power is supplied from a solar cell array 6 to the power system; and at an abnormal state of the power system, electric magnetic contactors 10, 11 and 14 are provided for supplying power to an independent operation load 15 from the solar cell array 6 and a battery 8 accompanied with the array 6 through one inverter 9d alone.
