Abstract
Residential system includes photovoltaic power system including solar battery, and electrical storage device including battery. Electric load of residential system is selectively supplied with energy from power supply system, power generator and electrical storage device. Power generator allows energy to flow back to power supply system. Energy surplus judgment part calculates difference between generating energy of power generator and demand power for electric load (excess generating energy). Overall operation controller applies stored energy in electrical storage device to demand energy for electric load when excess generating energy is produced, and charges electrical storage device without applying generating energy of power generator to demand energy when excess generating energy is not produced.
