MC4 Y Type

This MC4 Y Type connector is specially designed for solar photovoltaic systems, enabling fast parallel wiring of PV modules. It simplifies installation and eliminates the need for extra combiner boxes, cutting both difficulty and system costs while improving efficiency.

With standard industrial specifications, it combines the output of multiple PV modules or strings into one circuit, keeping voltage stable while increasing current. It supports DC 1000V/1500V and works with 30A/40A current, matching most PV cables for wide use in residential, commercial and off-grid solar systems.

The MC4 Y Type uses a foolproof design to prevent wrong insertion, with clear polarity for safer connections. It features IP67 waterproof and dustproof protection, strong UV and aging resistance for long outdoor use.

Low contact resistance and high conductivity ensure stable, efficient and safe operation of your PV system.

Strong Point
