Each cable and branch lead has been engineered to simplify setup, maximise current flow and reduce cable clutter. Built from high-quality, heavy-duty components, these leads ensure long-term reliability under the harsh conditions of outdoor travel. Featuring pre-assembled MC4 connectors and IP67 waterproof protection, the SPHERE range offers a clean, weather-sealed solution for extending or branching solar arrays. Every product in the series is designed to minimise voltage drop, handle high current output beyond the 30A MC4 limit, and resist UV, moisture and corrosion.

Designed for seamless solar integration, this SPHERE 1-to-2 staggered branch lead simplifies multi-panel setups by eliminating excess cable length and reducing the need for additional connectors. Each branch is staggered to prevent bunching, while the 6mm main output cable provides greater current capacity for stable power delivery.

Made for caravan and RV installations, it arrives pre-assembled with MC4 male and female connectors and is fully sealed to IP67 for outdoor reliability. Its heavy-duty construction and precision-matched cable lengths allow for tidy, efficient layouts that maintain peak energy transfer.
