IP67 Waterproof Solar Cable 4mm2 6mm2 for Solar Panel Wiring with MC4 Connector

Basically, if you're wiring up solar arrays and need something that won't quit when it's wet or UV-blasted all day, these cables handle that without a second thought—we've had them in the field for years with no degradation on teh jacket.

It's a double-insulated, halogen-free photovoltaic wire 1KV or 2KV, and the temperture range is -40°C to 105°C dry or 90°C wet, which pretty much covers every outdoor scenario you'd throw at it.

All our MC4 connectors come pre-crimped and 100% electrically tested, so you're not guessing if that connection will hold up after a storm; we also offer MC3 or panel mount if that's what your combiner box needs.

You can get it in 4mm2 or 6mm2, with male-to-male, male-to-female, or female-to-female ends, and we do custom lengths and colors—most buyers go with black or red, but it's your call.

We hold UL, ISO 9001, IATF 16949, RoHS, and REACH certs, so you're not just trusting a spec sheet; every batch ships with a COA, and tinned copper conductor resists corrosion better than bare copper for coastal installations.

One thing to know—these aren't ideal for direct burial without conduit (the jacket is tough but not armored), so if that's your plan, let us know and we'll recommend the right variant.
