Abstract
An inverter unit converts power from a solar battery into AC power and interconnects the AC power with a utility power supply. A control circuit manages the time during which the inverter unit stops. If the time is equal to or longer than a predetermined time, it is determined that one day has passed. Data for one day stored in a memory is accordingly cleared and data is newly stored in the memory.
