Photovoltaic inverter is to convert direct current (dc) to alternating current (ac) devices. Due to the solar battery and battery is a dc power supply, and when the load is ac load, inverter is indispensable in solar energy control system. Photovoltaic inverter according to the operation mode, can be divided into
photovoltaic inverter device is to convert direct current (dc) to alternating current (ac). Due to the solar battery and battery is a DC power supply, load is ac load, inverter in solar system is indispensable. Photovoltaic inverter according to its operation mode can be divided into independent photovoltaic inverter and photovoltaic (pv) grid inverter. 1. Independent photovoltaic inverter is used to run stand-alone solar cell power generation system, to the independent load power supply. Grid inverter is used in the parallel operation of the solar cell power generation system. Solar cells produce direct current (dc) in the sun, however, by the direct current power supply system has significant limitations. For example, solar street light control system, fluorescent lamp, TV, refrigerator, electric fans, etc. Not directly by the DC power supply, so most of the motor. In addition, when the need to raise or lower voltage power supply system, communication system only need to add a transformer, and the higher and lower voltage in the DC system technology is much more complex. Therefore, in addition to the communication and meteorological special users directly using the DC power, the power supply for production and life of photovoltaic power generation systems also need photovoltaic inverter. 2. Photovoltaic inverter is the core of the entire photovoltaic power generation systems. It not only can make the normal operation of photovoltaic power generation, it can real-time monitor the working state of the photovoltaic power station, bring convenience for maintenance.
