MC4-Y branch connectors for wiring solar panels in parallel. This pack includes one splitter that takes a single male MC4 to two female outputs and one that takes a single female MC4 to two male outputs - together they parallel two panels (or two strings) into one run back to your MPPT.

• One 1 male to 2 female and one 1 female to 2 male MC4-Y connector per pack.
• Combines two panels or strings in parallel - currents add, voltage stays the same.
• IP68, water-tight, with a secure locking fit.
• UV-resistant housing rated for outdoor and marine exposure.
• Check that your combined string current stays within your PV cable and MPPT ratings before paralleling.
