Classification of solar inverters

Solar inverter output can be divided into single-phase, three-phase and multi-phase solar inverters.

The switching circuit of solar inverter can be divided into resonant inverter, fixed frequency hard switching inverter and fixed frequency soft switching inverter.

The output frequency of solar inverters is divided into power frequency, medium frequency and high frequency inverters. The frequency of power frequency inverter is 50-60Hz, the frequency of medium frequency inverter is 400Hz to KHz, and the frequency of high frequency inverter is KHz to MHz.

The solar inverter is an important part of the solar power generation system and is mainly used to convert the DC power emitted by the solar panel into AC power that can be used in the AC grid. Solar inverters can generally be classified according to their output voltage, power, waveform and other characteristics. The following are the classifications of solar inverters:

1. Classification based on output voltage: The output voltage of solar inverters is generally divided into two types: DC output and AC output. DC output inverters are mainly used for solar pool strings, while AC output inverters generally output 220V or 380V AC power. This type of inverter is more common.
2. Classification according to power: The power of solar inverters can range from tens of watts to thousands of watts. According to the power classification, it can be divided into small power inverters, medium power inverters and high power inverters. kind.
3. Classification according to waveform: The output waveform of solar inverter can be divided into two types, one is a pure sine wave inverter, which outputs pure sine wave alternating current, and the other is a square wave inverter, which outputs square wave alternating current. The AC power output by pure sine wave inverter is of higher quality, but the price is relatively high. The price of square wave inverter is relatively low, but it affects the life of electrical equipment.
4. Other classifications: According to different usage scenarios, solar inverters can also be divided into household inverters, commercial inverters, etc.

To sum up, the classification of solar inverters mainly includes classification based on different characteristics such as output voltage, power, waveform, etc. Different types of inverters are suitable for different scenarios and uses. Users need to choose the appropriate inverter according to actual needs to achieve the best power generation effect.
