PV power generation is to convert the luminous energy to electric energy through the solar panel. The output of solar panel is direct current and the current output will be stored through the storage battery, providing electricity to load. There are two types of power supplying method, one is DC power supply and the other is AC power supply through the inverter. PV power generation system con- sists of solar battery, solar controller, storage battery (unit) and inverter. High-voltage DC contactor is mainly used at DC end in the PV power generation system, and storage battery and inverter are mainly used to switch to DC load. The general voltage range is 400-1000VDC and the current range is 10-120ADC.
The fundamental principle for wind power generation is to convert the energy of wind to mechanical energy through wind wheel and then switch to the electricity by generator. There are 3 kinds of generators available for the wind power generation, which are DC generator, synchronous and asynchronous AC generator. The electricity generated by wind power generator is generally not able to be applied to the circuit and shall be stored firstly. In the system of the wind power generator, the high-voltage DC contactor is mainly applied to the output terminal of DC and the input/output terminal of energy-storage battery. The general voltage range is 700-1000- VDC and the range for current is 100-200ADC.
