The photovoltaic inverter is the heart of the solar photovoltaic system. Its main function is to convert the direct current generated by the solar cell components into alternating current, which is incorporated into the grid or used by the load. Photovoltaic inverters can be divided into ordinary inverters, inverter/charging integrated machines, special inverters for post and telecommunications, and special inverters for aviation and military according to their application fields. It is composed of a logic control circuit, a filter circuit and an inverter circuit, and the inverter circuit is the core of the inverter.

(1) Ordinary inverter

DC 12V or 24V input, AC 220V, 50Hz output, power from 75W to 5000W, some models have AC and DC conversion or UPS function.

(2) Inverter/charger all-in-one machine

In this type of inverter, users can use various forms of power sources to supply power to AC loads: when there is AC power, the inverter uses AC power to power the load or charge the battery; when there is no AC power, the battery powers the AC load . It can be used in combination 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

The photovoltaic inverter has a 28Vdc input and can provide the following AC outputs: 26Vac, 115Vac, 230Vac, and its output frequency can be: 50Hz, 60Hz and 400Hz, and the output power ranges from 30VA to 3500VA. There are also DC-DC converters and frequency converters for aviation.
