How to improve the service life of photovoltaic inverters?

External environment for PV inverter operation

The external environment in which the photovoltaic inverter operates is also an important factor affecting the life of the inverter. At present, the protection level of string inverters on the market can reach IP65 or even IP66. It is dustproof, rainproof, and has the ability to resist salt spray corrosion. It can adapt to harsh external environments. In many places, because the dirt falls on the radiator, it will affect the function of the radiator. Dust, leaves, sediment and other fine objects may also enter the air duct of the photovoltaic inverter, which will also affect the heat dissipation, thereby affecting the service life. . In this case, it is particularly important to regularly clean the dirt on the photovoltaic inverter or cooling fan so that the inverter has good cooling conditions.

How to improve the service life of photovoltaic inverters? A photovoltaic inverter is an electronic product. Limited by the internal electronic components, it must have a certain service life. The service life of a photovoltaic inverter depends on the product quality, installation and use environment, and subsequent operation and maintenance. So, how to improve the service life of the inverter through correct installation and use as well as later operation and maintenance? Precautions for inverter installation and use The inverter must be installed in a well-ventilated space to maintain good ventilation with the outside world. If it must be installed in an enclosed space, air ducts, exhaust fans or air conditioning equipment must be installed. It is strictly forbidden to install the inverter in a closed box. The installation location of the inverter should avoid direct sunlight as much as possible. If the inverter is installed outdoors, it is best to install it under the eaves or solar modules on the back of the sun, with the eaves or modules above the inverter. If it can only be installed in an open place, it is recommended to install a sun visor above the inverter. Both single and multiple inverters should be installed according to the installation space size provided by the inverter manufacturer to ensure that the inverter has sufficient ventilation and heat dissipation space and operating space for future operation and maintenance. The inverter should be kept as far away as possible from high-temperature areas, such as boilers, oil-fired hot blast stoves, heating pipes and air conditioning exhausts. External environment for inverter operation The external environment for inverter operation is also an important factor affecting the service life of the inverter. At present, the protection level of series inverters on the market can reach IP65 or even IP66, which can be dustproof, rainproof and salt spray resistant, and adapt to the harsh external environment. However, in heavily polluted or dusty places, dirt falling on the radiator will affect the function of the radiator. Small objects such as dust, leaves, and sediment may also enter the air duct of the inverter, which will also affect heat dissipation. affect the service life. In this case, it is especially important to regularly clean the dirt on the inverter or cooling fan so that the inverter has a good cooling condition.
