Product Description

Solar MC4 1-to-3 Y Branch Parallel Connector Waterproof 4-Way Splitter for Photovoltaic Panels
The Solar MC4 1-to-3 Y Branch Parallel Connector is a high-performance photovoltaic combiner designed for optimizing solar array configurations. This IP68-rated 4-way splitter enables single-input-to-triple-output connectivity, allowing users to parallel connect three solar panels to a single charge controller or inverter input. Manufactured with flame-retardant composite materials (UL94V-0) and gold-plated contacts, it ensures maximum power transfer efficiency while withstanding harsh environmental conditions.
