A battery power supply system permits inexpensive introduction of a transfer break system to a solar cell generation system and quick release of reverse charge phenomenon. The battery power supply system comprises a solar cell array 1, a DC-AC inverter 2, a brake device 3 for a commercial power system, and wireless communication means 4 as control means for controlling the conduction and break of the break device based on the information derived through wireless communication. <IMAGE> |
