Photovoltaic Inverter Customized Fan

With the goal of carbon peaking, carbon neutrality, and "building a new power system with new energy as the main body", as a key technology in the sustainable development strategy of renewable energy, the photovoltaic power generation industry has ushered in a leap-forward development opportunity.

In recent years, countries including my country have successively issued a series of policies to actively support the expansion of the photovoltaic industry. By the end of 2021, the installed capacity of photovoltaic power generation grid-connected has reached 306 million kilowatts, breaking the 300 million kilowatt mark, and the industry has developed rapidly.

The photovoltaic inverter is the heart of the solar photovoltaic power generation system, which converts the direct current generated by the photovoltaic power generation system into the alternating current required for life.

The reliability and safety of photovoltaic inverters are directly related to the overall smooth operation of the solar power generation system, its conversion efficiency directly affects the power generation efficiency of the solar photovoltaic power generation system, and its service life is directly related to the service life of the photovoltaic power generation system, which ultimately affects the photovoltaic power station. The project's return on investment.

The current market is mainly dominated by centralized inverters and string inverters. The power range of centralized inverters is about 500kW-3MW, and they are mainly used in large-scale projects such as ground photovoltaic power stations with good lighting conditions; string inverters The inverter is in the range of 20kW-350kW. The distributed inverter product type is mainly used in small and medium-sized industrial and commercial and household photovoltaic power generation systems. In recent years, the voltage of photovoltaic power plants has been developed from 1,000V system to 1,500V. More photovoltaic modules are connected in series, which greatly reduces equipment, cable and construction costs, and increases power generation.

The fan is one of the important core components in the photovoltaic power generation system. The centralized photovoltaic inverter has a large power and usually adopts forced air cooling. Most of the inverters are placed outdoors, and the operating environment is relatively harsh. Therefore, the protection level of the whole machine is required to be high. Most of the fans are installed inside the equipment. Therefore, in order to ensure the compact structure of the equipment, the size of the fan should be selected as small as possible.

Photovoltaic inverter fan selection

The photovoltaic inverter fans professionally supplied by Hengrui Hongsheng have passed the practical test and have been put into photovoltaic inverter equipment. The size of the fan is 133-355mm, and the compact fan occupies less space in the biological safety cabinet; the high air volume up to 4200m3/h makes the photovoltaic inverter more efficient and stronger.

Heat dissipation method: module ventilation, local heat dissipation, whole cabinet ventilation, upward air supply and top air outlet.
