Abstract
In an AC module, if an interconnection relay is provided in an inverter, the inverter increases in size, and disconnection status between the AC module and a system upon occurrence of abnormal condition cannot be easily checked by a user. Accordingly, a plug is connected to an outlet, thereby an output of the inverter is supplied to the system or a load via a coupler. If leakage of direct current, ground fault of a solar cell or the like, a fault or abnormal condition of the inverter, or an abnormal condition of the system is detected, the inverter outputs a signal to separate the plug from the coupler.
Claims2
A connector for connecting an output of a power converter and an outlet connected to (i) a commercial power system or (ii) a load, comprising:
- a plug which is plugged in the outlet, and has a permanent magnet;
- and
- a coupler which couples the plug and the output of said power converter, and has an electromagnet excited by a signal provided from said power converters,
- wherein coupling of the plug and the coupler is released by the signal.
