Product Overview
This MC4 Y-branch solar wiring harness belongs to our
New Energy Cable Assembly series. Available in 2-to-4 and 2-to-6 branch layouts, designed for parallel connection of multiple solar panels.
The PV splitter cable simplifies solar array wiring layout, widely adopted in off-grid power systems, rooftop photovoltaic projects, RV solar setups and energy storage stations. Standard length 56cm in stock, and we support fully customized new energy cable assembly to match different installation space requirements.
Outstanding Product Performance
✅IP68 Waterproof & Reliable Sealing
Passed TUV lab testing under 1m water depth for 1 hour. Embedded locking structure prevents accidental separation. Stable connection under outdoor rainy, dusty environment.
✅ Wide Temperature Adaptability
Adopt high-performance PPO insulation material, UL94-V0 flame retardant. Working temperature range -40°C ~ +95°C, material resistance temperature reaches -40°C ~ +125°C, suitable for extreme outdoor climate.
✅Stable High Current Transmission
Tinned brass contact core, contact resistance ≤5mΩ. Rated voltage 1000V DC, maximum working current 30A. Effectively reduce heat generation during long-time photovoltaic power transmission.
✅Optimized Plug Mechanical Design
Insertion force ≤50N, pull-out force ≥50N. Self-locking mechanism ensures firm docking. Support 4mm² and 6mm² solar wire, compatible with mainstream photovoltaic cables.
