The Sola-Prod Solar Cable 4mm Black and Red 10m is a professional-grade, specialized photovoltaic DC power transmission cable pair engineered to connect solar panels securely to charge controllers, batteries, or hybrid inverters. Designed for solar installers, backup-power DIY enthusiasts, and residential property owners, this pre-allocated cable set ensures reliable electrical connectivity for renewable energy configurations. By utilizing high-purity conductor cores, it safely delivers clean DC energy across your infrastructure while minimizing power drops. If you need a reliable, compact pre-cut cabling solution to hook up your outdoor photovoltaic array to an adjacent indoor power station, this paired set provides the standard heavy-duty durability required.
Optimized energy transfer: The 4mm² cross-sectional core diameter reduces electrical resistance and line losses, ensuring that the maximum possible power generated by your photovoltaic panels reaches your regulator or inverter.
Dual-colour polarity identification: Supplied as a paired set containing distinct red and black cables to establish unambiguous positive and negative runs, eliminating wiring errors during terminal connections.
Convenient short-run length: The 10-metre matching allocation provides an ideal solution for compact installations, such as minor residential structures, outbuildings, or small arrays, without the waste or cost of large drums.
Weatherproof outdoor jacket: Formulated with specialized UV-stabilized and climate-resistant insulation designed to withstand continuous South African sun exposure, high temperatures, and seasonal moisture without cracking or degrading.

Note: MC4 cable connectors, solar panels, and mounting hardware are not included and must be sourced separately.
Standard household electrical wire or extension cords cannot be used for solar panel setups. Photovoltaic systems require specialized UV-stabilized cross-linked insulation because standard PVC wire jackets degrade rapidly under constant South African sun exposure, eventually causing hazardous short circuits.
A 4mm² core diameter is considered the industry sweet spot for small-to-medium residential solar applications. It efficiently handles the current loads of typical modern high-wattage panels while successfully containing voltage drops over shorter runs, protecting system performance.
Utilizing distinct red and black lines is vital for protecting your hardware investment. Reversing positive and negative polarities during installation, even for a split second, can instantly blow the input fuses or permanently fry the internal circuitry of an expensive MPPT charge controller or hybrid inverter.
