<P>PROBLEM TO BE SOLVED: To provide a system-cooperative inverter where there is no necessity to supply reactive power from a system and the increase of loss does not occur even in the case that much reactive power becomes necessary according to the configuration of a plurality of instruments used in a home. <P>SOLUTION: This system-cooperative inverter device is so arranged as to zero the reactive power to be supplied from the system to a home by providing a system voltage detection means 15 which detects system voltage waveform and a system current detection means 16 between the system as well as an inverter and the domestic load, and controlling the output current of the inverter 12 so as to accord the zero values of the output of both detection means with each other. <P>COPYRIGHT: (C)2004,JPO |
