This T-branch MC4 manifold replaces messy Y-harnesses and field-made parallel runs with a single, factory-sealed junction block. One main feed goes to the inverter or combiner box; N branches plug straight into your panel outputs, so the whole array ties together in minutes. No crimping, no extra extension cable, no waterproof tape — just plug and lock.
Built for real rooftop and ground-mount arrays, the housing is molded in UV-stabilized PPO rated UL94-V0, with tin-plated brass contacts that resist salt spray and high humidity. Once mated the whole thing seals to IP67, so rain, dust, and snow never reach the busbar. The snap-in MC4 locks hold tight against wind-driven panel movement, and the operating range covers -40°C winter install to +85°C summer rooftop heat. TUV tested to 6KV hipot and rated for 50A continuous, 1000V DC.
Available in 1-to-2, 1-to-3, 1-to-4, 1-to-5, and 1-to-6 configurations — order the branch count that matches your string.
