As the core of the power station, the life of the inverter affects the normal operation of the entire power station. The life of the inverter has become a problem that everyone is very concerned about. So what are the factors that affect the life of the inverter?
Temperature is one of the important factors affecting the life of the inverter, especially for components such as electrolytic capacitors and optocouplers. For every 10°C increase in temperature, the life of electrolytic capacitors is reduced by half. Excessive temperature will also accelerate the light wane of optocouplers.
When the relay is switched at zero current, its life is 1 million times. However, as the current increases during switching, the life is almost exponentially attenuated. Precise software control makes the relay switch at zero current, which is the key factor to ensure the life of the relay.
The working environment of the inverter is generally poor. And there are many interference factors, such as poor power grid quality, large local inductive load, etc. If the inverter protection function and EMC design are not good, it is easy to be disturbed by the outside world. Once the IGBT If the drive is disturbed, it is easy to cause it to misconnect and cause the machine to explode.
Although the string inverter has an IP65 protection level and can be installed both indoors and outdoors. But the installation environment also has a great impact on the life of the inverter. If the inverter is installed in an environment with direct sunlight, humidity, and high pH, the life of the inverter will be shortened. And in an environment exposed to the sun, it will easily cause the inverter to overheat and reduce the load, which will affect the power generation. Therefore, choosing a suitable installation environment is also a key factor to ensure the life of the inverter.
