Solar Wire Harness Manufacturing for Photovoltaic Systems
As a specialized solar wire harness manufacturer, OurPCB delivers UV-resistant, outdoor-rated cables for photovoltaic systems. Our cable assembly expertise covers MC4-compatible connectors, DC power cables up to 1500V, and pre-terminated string cables meeting UL 4703 and TUV standards for 25+ year outdoor life.
Panel connections include module interconnects, string wiring, and junction box cables for residential and commercial arrays. Inverter cables handle DC input, AC output, and monitoring connections. Waterproof cables protect electrical connections from rain and humidity.
Energy storage cables connect battery systems in hybrid solar installations. Anderson connectors provide secure, high-current connections. Our EV and new energy capabilities support complete renewable energy systems.
Pre-terminated string cables reduce installation time with factory-quality connections. Custom lengths match specific array configurations. Rapid shutdown wiring meets NEC 2017/2020 code requirements for rooftop safety. Power harnesses handle DC and AC distribution.
PV wire, USE-2, and XLPE insulated cables withstand decades of UV exposure and temperature cycling. Our testing capabilities verify electrical performance. Contact us for solar wire harness quotes for residential, commercial, or utility-scale installations.
Solar FAQ
We manufacture PV wire, USE-2, and XLPE insulated solar cables in various gauges. Our cables are rated for outdoor use with UV-resistant jacketing and meet UL 4703 and TUV standards for photovoltaic applications.
Yes, we assemble cables with MC4 and MC4-compatible connectors. We also work with other solar connector types from Amphenol, TE, and other manufacturers. All connections are properly crimped and tested.
We manufacture pre-terminated string cables cut to specific lengths with connectors installed. This reduces installation time and ensures consistent, factory-quality connections. Custom configurations are available.
We can integrate rapid shutdown components and wiring into our harness assemblies to meet NEC 2017/2020 requirements. We work with your system design to provide compliant solutions.
