What is IP21, IP65, IP66 Solar Inverter Protection Rating?
IP (Ingress Protection) ratings indicate the level of protection an electrical device, like a solar inverter, has against dust and water. Here’s what IP21, IP65, and IP66 mean for solar inverters:
- IP21: Protects against solid objects larger than 12.5mm and vertically falling water drops. Suitable for indoor use only.
- IP65: Fully protected against dust and resistant to low-pressure water jets from any direction. Suitable for outdoor installations.
- IP66: Fully protected against dust and powerful water jets. Offers higher water resistance than IP65, making it ideal for harsh outdoor environments.
Higher IP ratings ensure better durability and longevity in extreme weather conditions.
