SPHERE MC4 Solar Staggered 1 to 3 Branch with 5m HD Extension

The SPHERE MC4 range delivers professional-grade solar connectivity designed for modern caravan and RV installations. 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. Whether youre linking panels or extending reach, SPHERE delivers the confidence of a precise, factory-grade connection, ready for life on the road.

Expand your solar capacity with this 1-to-3 branch lead designed for seamless array installation. The staggered branch design prevents cable overlap and clutter, while the heavy-duty 6mm output ensures stable power delivery even in high-load systems. Perfect for multi-panel RV and off-grid configurations where neatness and performance matter equally.

Pre-assembled MC4 connectors make installation quick and secure, while the IP67-rated construction protects against dust, moisture and UV damage.
