Description
This Stäubli MC4 PV extension cable is precision-assembled at our Northern California facility using genuine Stäubli MC4 connectors and UL 4703-rated solar wire — built for installers who refuse to compromise on quality, compliance, or long-term field performance.
Constructed with 10AWG 19-strand bare copper conductors and cross-linked insulation rated to 2,000V, this cable delivers the current-carrying capacity, flexibility, and weather resistance that demanding solar installations require from the first day of operation to the last.
Whether you are extending strings on a rooftop array, completing home-run connections on a ground-mount system, or adding reach to an existing PV string, this cable is engineered to perform cleanly and reliably in every application. Its IP68 and IP65 ratings ensure full protection against water and dust ingress in the harshest outdoor environments.
Every cable is precision-assembled for reliable connector mating and consistent electrical contact, eliminating the field reliability concerns that come with lower-quality pre-made alternatives. Custom lengths are available upon request.
