The Suntree Y2 MC4 Connector is a high-quality parallel branch connector designed to combine or split solar panel outputs safely and efficiently. This “Y-type” MC4 adapter allows two solar panels to be connected in parallel, feeding power into a single input—simplifying wiring and reducing voltage while increasing current.
Constructed from weather-resistant materials and built to handle high current loads and outdoor exposure, the Y2 MC4 is ideal for expanding solar arrays in off-grid, residential, and commercial systems. It ensures a safe, plug-and-play experience with standard MC4 connectors, making it a preferred solution for installers looking to parallel connect multiple panels quickly.

Parallel connection of solar panels in off-grid systems
12V or 24V battery charging arrays
RV, camper, or mobile solar setups
Residential rooftops requiring string expansion
DIY solar kits and portable power stations
Connect the two MC4 male (or female) ends to the outputs of each solar panel.
Connect the single branch output to the solar charge controller or combiner input.
Ensure connectors snap into place with an audible click.
Use MC4 spanners to disconnect if needed for service or maintenance.
Inspect connections periodically to ensure sealing and performance.
