What is the inverter IP protection rating?
In the technical specifications for inverters, the term "protection rating" is often seen. So, what is the IP protection rating?
The IP protection rating (Ingress Protection Rating) is a standard established by the International Electrotechnical Commission (IEC) to define the effectiveness of an electrical device's enclosure in protecting against foreign objects (such as dust, tools, fingers, etc.) and water. This rating consists of two digits: the first digit represents the level of protection against solid foreign objects, and the second digit indicates the level of protection against liquids. The higher the number, the stronger the protection.
Inverters with an IP65 rating or higher mean that the inverter's sealing performance is reliable, and each inverter has passed rigorous airtightness tests before leaving the factory.
However, during machine fault repairs, we have noticed that many users' inverters contain foreign objects inside, such as insects and dust. If such situations occur, they may cause machine malfunctions, resulting in the inability to generate power. In more severe cases, they could even lead to machine damage. Therefore, proper sealing during the installation of inverters on-site is also crucial. This is especially important when inverters are installed in outdoor or humid environments. A good seal can effectively prevent moisture, dust, and other contaminants from entering the device, thus avoiding corrosion and damage to the circuit boards and electronic components.
