<p>PROBLEM TO BE SOLVED: To suppress the early exhaustion of the service life of a specified inverter by making one inverter defined as a host machine control the start/stop of remaining inverters ordered from this inverter on the basis of prescribed rules and increase/decrease in the power generation quantity of a DC power source or increase/decrease in the AC mass from the inverter. SOLUTION: When the solar battery module of a DC power source 1 starts generating power, a remote controller 50 of an inverter 14, which first starts operating, becomes the host machine. This remote controller 50 declares the host machine through a signal line to other remote controllers 50 so that the host machine and slave machines can be determined. Afterwards, the remote controller 50 set as the host machine makes the connected inverter 14 into active state at all the time and starts/stops the inverters 14 connected to the remote controllers 50 as slave machines corresponding to increase/decrease in the output power of the DC power source 1.</p> |
