How to Improve the Heat Dissipation Efficiency of Solar Inverter?

1. Know the solar inverter


The solar inverter is the core equipment of the solar power generation system, and its main function is to convert DC electricity generated by photovoltaic components into AC power that meets the requirements of the state grid. Nowadays, many people choose to install household solar inverter equipment, which directly converts solar energy into electricity. This is not only environmental and friendly, but also can save money on electricity bills. When using, it is also necessary to pay attention to the maintenance of the solar power inverter equipment. Then how to improve the heat dissipation efficiency of the equipment, so as to prolong the service life of the equipment?


2. Improve the heat dissipation efficiency of solar electric inverters


First of all, we should understand that the heat dissipation system of the solar inverter mainly includes heat sink, cooling fans, heat conduction silicon grease and other materials. At present, there are two main methods of inverter heat dissipation: one is natural cooling, and the other is forced air cooling.


Natural cooling refers to the realization of local heating devices' heat dissipation to the surrounding environment without using any external auxiliary energy, so as to achieve the purpose of temperature control. Usually, it includes three main heat transfer modes: heat conduction, convection and radiation, among the convection, natural convection is the main way. Natural heat dissipation or cooling is often suitable for low-power devices and components with low temperature control requirements and low heat flow density of device heat, as well as devices that not suitable to be sealed or be dense assembly by other cooling technologies.


Forced air cooling is mainly a method of taking away the heat emitted by the device through making the surrounding air flow with the help of a forced device such as a fan. This method is a heat dissipation method with simple operation and obvious effect. If the space between the components in the device is suitable for air flowing or is suitable for the installation of local radiators or fans to dissipate heat, then this cooling method can be used as much as possible.


After understanding the two heat dissipation methods of solar power inverter equipment, it is natural to think that the inverter should choose fan to dissipate the heat. So we will discuss the installation requirements of the fan radiator inverter here, because fan cooling requires an external radiator of the inverter. Therefore, the installation space is required, and there also needs to be a gap large enough between the components of the inverter to ensure that the airflow can enter the heat and circulate. And Anern solar inverter is a wonderful choice if you want to buy solar inverter online.


To achieve the best heat dissipation effect of photovoltaic inverters, in addition to knowing the heat dissipation type, we should also ensure that the installation space is large enough. If multiple inverters are installed side by side, please pay attention to the gaps between them and the position of the cooling fan. In fact, the inverter is not only the inverter, but also the safety manager of the photovoltaic power station. Solar electric inverters also undertake the monitoring and protection of photovoltaic arrays and power grids, as well as the protection of the external environment and human-computer interaction and other system-level functions.
