Document Type and Number:
Japanese Patent JP3330157
Kind Code:
B2
Abstract:
PURPOSE:To improve the utility of a solar battery in the excessively charged state of an accumulator in a solar battery system in the summer season and to effectively use the solar battery at the time of stopping the running of a solar battery/commercial power supply shared type air conditioner system. CONSTITUTION:When an air conditioner 5 is stopped, an output from a solar battery array 1 charges the accumulator 2 with electricity, the charged electricity is converted into AC 100V by a power control circuit 3 and power is supplied to an AC load 4. When the air conditioner 3 starts to run, the output of the array 1 is converted into high frequency power by an FET bridge 7, the voltage of the power is boosted by a voltage doubler rectifier circuit 9 and the boosted power is inputted to a VVVF inverter 5b in the air conditioner 5.
