What Is A PV Inverter?



A pv inverter is a device that converts DC to alternating current. Because it corresponds to the reverse process of rectifying, it is called inverter.

The solar cell produces DC under the sunlight, but the system that is powered by direct current is very limited. For example, fluorescent lamps, TV sets, refrigerators, electric fans and so on can not be directly supplied by direct current power supply, so is the vast majority of electric machinery. In addition, when the power supply system needs to raise voltage or reduce voltage, the AC system needs only one transformer, and the technology of raising and lowering voltage in DC system is much more complicated. Therefore, in addition to the direct use of DC power, such as communications and meteorology and other special outdoors, photovoltaic inverter is needed in the photovoltaic power generation system that produces and uses household electricity.
