Abstract
An inverter device, which has two operation modes including a grid-connected operation mode where the inverter device is interconnected with a commercial power system, and an isolated operation mode where the inverter device is independent of a commercial power system and performs an isolated operation, includes an inverter converting direct-current power received from a direct-current power supply of a solar battery array into alternating-current power, a control unit controlling an action of an inverter device, a plug for outputting the alternating-current power converted by the inverter, and a load-connecting receptacle on a path of a power supply line connecting the inverter and the plug, for outputting the alternating-current power.
Claims7
An inverter device having two operation modes including a grid-connected operation mode where the inverter device is interconnected with a commercial power system, and an isolated operation mode where the inverter device is independent of said commercial power system and performs an isolated operation, comprising:
- an inverter unit converting direct-current power received from a direct-current power supply into alternating-current power;
- a control unit controlling an action of said inverter device;
- a grid-connected output terminal for outputting the alternating-current power converted by said inverter unit,
- said grid-connected output terminal being a plug connectable to a commercial receptacle, commercial power from the commercial power system being supplied to the commercial receptacle;
- and
- an isolated operation output terminal provided on a path of a power supply line connecting said inverter unit and said grid-connected output terminal, for outputting said alternating-current power,
- said isolated operation output terminal being a receptacle a load is connectable to, the load being supplied with said alternating-current power.
