Solar Extension Cable

Easy Solution for Wiring Distance Issues

 

Jiangsu Jingwei Cable Co., Ltd. offers the solar extension cable as a practical solution for on-site installation challenges. This product solves the distance mismatch problem between solar panels, inverters, and controllers. It uses a high-purity tinned copper conductor and electron-beam cross-linked low-smoke halogen-free polyolefin insulation and sheath. This product provides excellent flexibility and weather resistance. It operates stably from -40°C to +90°C. The tinned copper conductor offers better corrosion resistance than bare copper. It prevents increased contact resistance from oxidation over long-term use. This ensures stable system efficiency throughout the cable's life.

Our solar extension cable has two core advantages. First, it comes with compatible MC4 connectors for plug-and-play installation. You do not need special tools on site. One person can complete the wiring. Second, we support custom lengths from 1 meter to 100 meters. Every product passes 100% continuity and voltage tests before shipment. This guarantees that every customer receives a certified product. Our monthly production capacity is over 55 million USD. More than 300 global partners use our product for their installations.

This solar extension cable is widely used in on-site installations that require extended wiring distances. In residential rooftop projects, the product extends panel output lines to indoor inverters. In off-grid systems, it transmits DC power from panel arrays to controllers or batteries. For outdoor camping and RV solar systems, the product provides flexible layout options. It also works for solar street lights and monitoring equipment power supply. We offer complete customization for this solar extension cable. You can choose any length from 1 to 100 meters. We can pre-install MC4 compatible connectors. We also customize printing and sheath colors. Our R&D team can develop custom samples within 7-15 days. Mass production takes 30 days after order confirmation. We hold ISO 9001, ISO 14001, and ISO 45001 certifications.
