Custom lengths for the actual routing
Cable assemblies fabricate to a project's specific run lengths and routing path, cutting the field splicing and excess coiled cable that come with standard pre-cut lengths.

Cable Assemblies
Source custom-length solar cable and wire harness assemblies with project-specific connectors and certifications. Cable fabrication services on Sunhub.
Cable assemblies matched to your routing
Connector and harness options matched to equipment
Connector types and harness configurations get specified against the exact inverter, combiner and disconnect hardware in the bill of materials, not assumed compatible.
Certified for the environment it's installed in
Outdoor and rooftop-rated cable assemblies carry the certifications an inspector checks, whether that's UV resistance, temperature rating or a specific UL listing.
Less splicing, confirmed connector compatibility
Cut field splicing and excess cable
Custom lengths match the actual run, reducing waste and the splices that become failure points later.
Confirm connector compatibility before it ships
Harness configurations get checked against the actual equipment list, not assumed.
FAQs
When does a project need a custom cable assembly instead of standard PV wire?
A custom assembly makes sense when the routing calls for specific lengths, connectors, or a harness that standard PV wire would require field splicing to achieve. Pre-terminated, cut-to-length assemblies cut splice points and leftover cable, which reduces failure points and install labor. Sunhub builds them to the project's actual routing and confirms connector compatibility before they ship.
What connector types are available for custom cable assemblies?
Assemblies can be built with common industry connectors matched to the modules, inverters, and combiners on the project, including MC4 and compatible types, along with harness configurations for paralleling strings. Because connector families are not always cross-compatible, Sunhub confirms the exact connector against the equipment before the assembly ships.
Are custom cable assemblies certified for outdoor and rooftop use?
Yes. Assemblies are specified with cable and connectors rated for the environment they are installed in, including sunlight, wet, and rooftop exposure, so they hold up to outdoor conditions and code requirements. The specific certifications are matched to the application, and Sunhub confirms the right rating for the installation before building the harness.
