Function and classification of solar inverter


The solar AC power generation system is composed of solar panels, solar charge controllers, inverters and batteries.


The function of the inverter


The inverter is a power conversion device. Its main function is to invert the DC power of the battery into AC power. 

Through the full bridge circuit, the SPWM processor is generally used for modulation, filtering, boosting, etc. to obtain the load frequency, rated voltage, etc. 

The matching sine wave AC power is used by the end users of the system.


Classified by application range :

1. Ordinary inverter


DC 12V or 24V input, AC 220V, 50Hz output, power from 75W to 5000W.


2. Inverter/charger integrated machine


In this type of inverter, users can use various forms of power sources to power AC loads: when AC power is available, the inverter uses AC power to power the load or charge the battery. When there is no AC power, the battery is used to supply power to the AC load. It can be used in conjunction with various power sources such as batteries, generators, solar panels, and wind turbines.


3. Special inverter for post and telecommunications


Provide high-quality 48V inverters for post and telecommunications, communications, and its products are of good quality, high reliability, modular (1KW module) inverters, and have N+1 redundancy function, expandable (power from 2KW to 20KW ).


4. Special inverters for aviation and military


This type of inverter has a 28Vdc input and can provide the following AC outputs: 26Vac, 115Vac, 230Vac, the output frequency can be: 50Hz, 60Hz and 400Hz, the output power ranges from 30VA to 3500VA, and there are DC- DC converters and frequency converters.
