<P>PROBLEM TO BE SOLVED: To provide a power linkage changeover system and a power linkage changeover method by which the convenience in the changeover of operation can be enhanced. <P>SOLUTION: The power linkage changeover system has a DC to AC converter part 11 for converting the DC power generated by a solar battery module 1 to AC power, and further comprises an inverter 10 for bringing the solar battery module 1 and an AC power system 2 into interconnected operation, and a remote controller 20 for remotely controlling the inverter 10 to switch the linkage operation and self-operation. The inverter 10 has a linkage operation relay 13, disposed between the AC power line 2w and the DC to AC converter part 11, for supplying AC power to the AC power system 2 in the linkage operation. The remote controller 20 has a self-operation output plug socket 21 for supplying AC power to a self-operation load Lsd in self-operation, and a self-operation power line 21w for connecting the self-operation output plug socket 21 to the DC to AC converter part 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
