FAQS

1. Are these MC4 connectors TUV and UL certified for use in utility-scale solar installations?
Yes, these MC4 connectors for solar panels comply with TUV and UL standards, making them suitable for both residential and utility-scale PV systems requiring certified solar panel wire connectors.
2. Can I use these solar connectors with 1500V DC systems, or are they limited to 1000V?
This particular MC4 connector variant is rated up to 1000V DC. For 1500V compatibility, please confirm the variant, as some versions are designed for higher voltage PV arrays.
3. Are these connectors compatible with 6mm² PV wire and crimped contacts, or only with soldered joints?
Yes, they fully support 2.5mm² to 6mm² PV cable via crimped tinned copper contacts — soldering is not required for standard MC4-compliant installations.
4. Is the IP67 rating still valid after multiple connection/disconnection cycles in outdoor environments?
The solar connectors maintain their IP67 waterproof rating when properly mated and locked; however, repeated disconnections may degrade sealing. For permanent installations, limit reconnections.
5. Can these MC4 connectors handle temperature cycling between -40°C to +85°C in rooftop setups?
Yes, these MC4 connectors are designed with PPO insulation material, allowing stable performance across extreme temperatures from -40°C to +85°C, ideal for rooftop or desert environments.
