Stäubli MC4 Evo 2 Connector 'h' Branch Pair 2 to 1

High-Performance Parallel Solar Wiring with Stäubli MC4 Evo 2 Branch Connectors

When expanding your solar array or optimising your system for shaded conditions, connecting your solar panels in parallel requires safe, robust, and highly efficient components. The Stäubli MC4 Evo 2 Connector 'h' Branch Pair 2 to 1 provides an industry-leading solution for parallel solar wiring. Designed as a plug-and-play mechanism, this branch connector allows you to link two panels to a single output effortlessly, completely removing the need for complex crimping or torquing during installation.

Industry-Leading MULTILAM Technology

Low-grade or generic solar connectors often suffer from poor contact pressure, which can lead to dangerous hot spots, electrical arcing, and significant power loss. Stäubli addresses these critical risks through its proprietary MULTILAM contact technology. This advanced internal spring-contact system ensures constant, optimal contact pressure across the connection surface. The result is consistently low contact resistance (under 0.5 mΩ), ensuring maximum power transfer and significantly reducing the risk of thermal failure, even under heavy electrical loads up to 60A.

Optimising Shaded Performance with Parallel Wiring

Connecting solar panels in parallel is a highly effective strategy for systems exposed to partial shading, such as those mounted on caravan roofs or marine canopies. By using an MC4 parallel connector, the voltage remains constant while the current increases. This means that if one panel is shaded by a tree branch or mast, the unshaded panel continues to operate at full capacity. The Stäubli Evo2 connector facilitates this parallel connection safely, accommodating the combined current output without generating excess heat.

Engineered for Extreme Australian Conditions

Solar installations are subjected to intense environmental stress, from blistering outback heat to corrosive coastal air. These parallel MC4 connectors are rigorously tested to withstand harsh extremes. Featuring an exceptional IP65 and IP68 protection rating when mated, they are entirely dust-tight and capable of surviving complete submersion in water up to one metre for an hour. Furthermore, their high resistance to UV radiation, salt mist, and ammonia makes them an exceptional choice for marine vessels, coastal off-grid homes, and mobile RV setups.

Seamless Compatibility and Dual Certification

Upgrading or expanding an existing solar system is straightforward. This MC4 branch connector is fully cross-compatible with both original Stäubli MC4 and newer MC4 Evo 2 connectors, allowing for seamless integration into your current array without replacing existing cable ends. It stands out as the world's first dual-certified DC 1500 V branch connector, meeting stringent IEC 62852 and UL 6703 safety standards. This high-voltage rating makes it suitable not only for 12V and 24V mobile applications but also for large-scale, high-voltage industrial setups.
