Why should we pay attention to the ventilation of inverters?

The inverter is a high-power electronic device. If the inverter does not dissipate heat well, it will lead to excessive internal temperature of the inverter. Sustained high temperature will cause cumulative damage to components such as high-power thyristors, large-capacity capacitors on the DC bus, integrated circuits, resistors, and inductors. At the same time, if the internal temperature of the inverter is too high, it will cause the inverter to reduce its output. This reduces the power generation of the inverter. When the temperature further rises and exceeds the threshold, it will trigger the over-temperature protection of the inverter, resulting in the inverter shutting down.
Therefore, it is very important to install the inverter in a place with good ventilation. At the same time, in the operation and maintenance of the power station, it is necessary to ensure that the inverter has good ventilation, the cooling fan operates well, the fan blades are undamaged, there is no dust accumulation, and the bearings are well lubricated. An inverter that operates at normal temperature with good ventilation can not only greatly increase its service life but also help improve the conversion efficiency and power generation of the inverter.
