How long is the service life of PV inverter protective vents

Material quality is a core factor determining service life. Vents made of high-quality plastic such as polyamide or polypropylene usually have better resistance to aging and corrosion, which helps extend their service life. Metal vents, especially those made of stainless steel or aluminum alloy, have superior mechanical strength and can withstand harsh environmental impacts, but their service life may be affected by factors such as oxidation and rust if not properly treated. Composite materials that combine the advantages of plastic and metal can further improve durability under complex conditions.

The operating environment has a significant impact on the service life of vents. Vents used in outdoor environments are often exposed to sunlight, rain, humidity, salt spray and dust, which can accelerate material aging, cracking or deformation. In contrast, those used in indoor or well-ventilated environments with stable temperature and humidity are less affected by external factors and can maintain better performance for a longer time. In areas with severe weather conditions, the service life of vents may be significantly shortened without additional protective measures.

Regular maintenance also plays a key role in extending service life. Timely cleaning of dust, dirt and debris on the surface and inside of vents can prevent blockage and reduce the burden on protective structures. Checking for signs of damage such as cracks, looseness or sealing failure and taking timely repair or replacement measures can avoid further damage to vents and ensure their long-term stable operation.
