MC4 Y-Branch 3-to-1 Branch Joiner Solar Connector Pair

Streamline your solar panel installation and maximise power output with the MC4 Y-Branch 3-to-1 Branch Joiner Connector Pair. Designed to combine the output of up to three solar panels into a single string, this connector reduces wiring complexity and simplifies array expansion — ideal for both professional installers and DIY enthusiasts.

Key Features

IP67 Waterproof & Dustproof: Premium PC/PA insulation with UV-resistant construction, built to perform in all weather conditions including extreme heat and heavy moisture.

Plug-and-Play Installation: Industry-standard MC4 snap-in locking mechanism for rapid, secure, tool-free connection — reducing labour time during array integration.

Optimised Energy Transfer: Tin-plated copper alloy contacts with low contact resistance (0.5mΩ) minimise energy loss and maximise power transfer from array to inverter.

Parallel Configuration: Efficiently links three solar panel strings into a single conduit — ideal for expanding system capacity without complex custom junction boxes.

Safety Compliant: Meets rigorous international standards including IEC and TÜV certification for long-term electrical safety and reliability.
