The Suntree Y-MCE 3-to-1 MC4 Cable Connector is a reliable solar connector designed to combine three solar panel outputs into one input. This makes it an ideal solution for parallel wiring of solar panels in off-grid, hybrid, or grid-tied photovoltaic (PV) systems. It helps maintain system voltage while increasing current, streamlining installations and reducing the number of connection points.
Made with high-quality, UV-resistant PPO insulation and tinned copper contacts, this Y-branch connector ensures secure and weatherproof connections in harsh outdoor environments. The plug-and-play MC4-compatible design guarantees compatibility with standard solar cables and connectors.

Match the 3 panel leads (positive or negative) to the corresponding connector.
Insert the connectors until they snap securely into place.
Connect the single output end to the charge controller, inverter, or combiner box.
Use MC4 spanners to disconnect when required.
Avoid pulling or bending cables near the connectors.
