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.
Claims9
A power generator comprising:
- a power converter which converts direct current power into alternating current power;
- a connector which connects an output of said power converter to a commercial power system or a load;
- and
- a signal outputting section which supplies a signal to release connection to said connector.
A control method of controlling a power generator which has a power converter which converts direct current power into alternating current power and a connector which connects an output of said power converter to a commercial power system or a load, comprising the steps of:
- detecting leakage of said direct current power to said commercial power system, ground fault of a solar cell to supply said direct current power, a fault or abnormal condition of said power converter and an abnormal condition of said commercial power system;
- and
- if an abnormal condition has been detected, a signal to release connection is supplied to said connector.
