The IP67 rating is real but only when connectors are fully mated—leave an MC4 half-exposed to weather and you'll get moisture ingress within weeks, so plan your terminations accordingly.
We've seen these harnesses hold up for 8+ years in rooftop arrays across Arizona and Nevada, the UV retardant additive in the XLPE jacket doesn't just slow cracking, it keeps the insulation flexible at -40°C dry conditions which matters more than most buyers realize.
You'll get tinned copper conductors as standdard, which basically eliminates galvanic corrosion at the MC4 crimp points, and the double insulation means you can run 1KV DC through these without worrying about dielectric breakdown even at 90°C wet.
What it does is handle teh link between your panels and the combiner box, or form the inverter to the battery bank—it's not suited for direct burial appliction though, the round profile and LSZH jacket don't have the mechanicla armor for underground runs.
Typical lead time for custom lengths is 15 days or so for 50 units, we keep black and red 2-meter male-to-female cables in stock, but if you need REACH-compliant halogen-free silicone rubber with a 2KV rating, expect about 20 working days.
We typically start at 100 sets for standard configurations, but if you need a custom length or color, we can work with you on a lower MOQ for sample orders.
Lead time for custom orders is usually 7 to 15 days after approval, depending on volume. Standard lengths ship faster, often within 5 days.
Yes, we include UL and ISO 9001 certificates with each batch, and IATF 16949, RoHS, and REACH docs are available on request.
Absolutely, we offer silicone rubber as an insulation option, and it handles the full -40°C to 105°C dry range. Just specify that when you order.
We pack harnesses in UV-resistant poly bags or cartons, and for large shipments, we use sealed export-grade packaging to keep them dry and protected.
