Why Use Photovoltaic Inverter In Solar Photovoltaic Power Generation?
Nov 02, 2017

The principle of solar photovoltaic power generation is the use of semiconductor interface, the effect of photovoltaic and direct conversion of light into a power technology. The key component of this technology is solar cells. Solar cells through the series after the package protection can form a large area of the solar cell components, and then with the power controller and other components to form a photovoltaic power generation device. The whole process we call the photovoltaic power generation system, photovoltaic power generation system is composed of solar cell array, battery, charge and discharge controller, photovoltaic inverter, AC distribution cabinet, solar tracking control system and other equipment.

A photovoltaic inverter is a device that converts direct current into alternating current. As the solar cells and batteries are DC power, and the load is AC load, the inverter is essential. PV inverter according to the mode of operation, can be divided into independent operation of the photovoltaic inverter and photovoltaic grid inverter. Independent operation of photovoltaic inverter for independent operation of the solar cell power generation system, for the independent load power supply. Grid-connected inverter for grid-connected solar cell power generation system. Solar cells in the sun under the direct current, but the form of DC power supply system has great limitations. For example: fluorescent lamps, televisions, refrigerators, electric fans, etc. can not directly use DC power supply, the vast majority of electric machinery is also true. In addition, when the power supply system needs to raise the voltage or reduce the voltage, the AC system can only add a transformer, and in the DC system to lift the voltage technology is much more complex. Therefore, in addition to direct use of DC power supply communications, weather and other special users, the supply of electricity in the production of photovoltaic power generation systems need to be equipped with photovoltaic inverter.
