Do connectors for photovoltaic inverters need to be UV-resistant?

Q: Do connectors for photovoltaic inverters need to be UV-resistant?

A: Yes, it is a must. The SP series waterproof connectors (IP68) are recommended. Their shells are added with UV stabilizers (compliant with ISO 4892-3 UVB 313nm standard), enabling them to resist outdoor UV radiation with a service life of ≥10 years, which far exceeds the connector replacement demand during the 25-year service life of photovoltaic power stations. They also adopt an anti-reverse insertion design (to avoid inverter burnout caused by polarity reversal), with 2 pins for transmitting DC power (voltage 1500V).
