Solar inverters are a key component of the entire solar power system. It can directly control the current, voltage and power output of the solar power generation system. In addition, the operation and shutdown of the solar power supply system, and its maximum power tracking and limiting are controlled by the
solar inverter, and almost most of the solar generator function control is completed by the inverter.
The application range of
solar inverters can be divided into ordinary inverters, inverters, and inverters for communication. In addition, the type of inverter can also be distinguished according to the output current waveform, the current output by the inverter can be square wave, trapezoidal wave or sine wave. For some complete inverters, the shape of the current output can be adjusted, that is, an inverter can output a variety of different currents. In addition, there are many other ways of dividing the inverter. For example, it can be divided into low frequency inverter, intermediate frequency inverter and high frequency inverter according to the frequency of the current, and it can also be divided according to the circuit form of the inverter.
There are many main performance parameters of solar inverters. The first consideration should be the application environment of the inverter. The solar controller includes application temperature and altitude. In addition, the rated output voltage of the inverter is also the main performance reference index when purchasing. The output voltage of a solar power generation system mostly has voltage fluctuations. Some instruments are more precise and require small voltage fluctuations. The voltage fluctuation of most inverters is between 3% and 5%.
