SHIVERPEAKS PV4 Extension Cable Set, 4mm², 2-Pack Black/Black, 25m (BS02-32105)

For solar installations where every meter of cable must survive harsh UV exposure, temperature swings, and constant load, the SHIVERPEAKS PV4 Extension Cable Set delivers a robust 25-meter reach per cable with a 4 mm² tinned copper core. Unlike generic extension leads that degrade within seasons, this pair of black photovoltaic cables is built for permanent outdoor deployment, featuring XLPE insulation and a halogen-free, UV-resistant jacket that keeps performance stable from -40°C to +90°C. Each cable is pre-terminated with weatherproof MC4 connectors (IP67) on both ends, so you can extend panel-to-inverter or panel-to-panel runs without soldering or additional tooling. The set includes two identical 25 m cables, giving you 50 m of total length for symmetrical string wiring or spare capacity. Rated for 1000 V DC and 30 A, it matches the output of modern high-efficiency modules while meeting TÜV and CE requirements. Whether you are commissioning a rooftop array, a ground-mount system, or a mobile solar trailer, this cable pair eliminates the weak points that cause voltage drop and connector failures in the field.

Highlights

• Two 25 m extension cables with 4 mm² tinned copper conductors for low resistance and long-term corrosion resistance.
• Pre-assembled MC4 male and female connectors on each cable, rated IP67 for dust-tight and water-resistant mating.
• XLPE insulation and UV-resistant, halogen-free outer jacket withstand direct sunlight, rain, and temperature extremes from -40°C to +90°C.
• Rated for 1000 V DC and 30 A, suitable for most residential and commercial PV strings.
• Certified to TÜV and CE standards, ensuring compliance with European safety directives.
• Flame-retardant construction adds an extra layer of safety in rooftop and enclosed installations.

In daily use

Route these cables along module frames, through cable trays, or underground in conduit without worrying about insulation cracking or connector loosening. The black jacket blends discreetly with mounting rails and roof surfaces, while the flexible yet tough construction allows tight bends without kinking. Because both cables are identical, you can use one for the positive run and one for the negative, or keep a spare on hand for future expansion. The MC4 connectors click securely into standard PV panels, optimizers, and inverters, and their IP67 rating means they can be left exposed to rain and dust. For installers, the 25 m length reduces the need for mid-run splices, cutting installation time and potential failure points. When the array is live, the tinned copper core maintains conductivity even in humid or coastal environments, preventing the green corrosion that plagues bare copper over time.
