Staubli MC2/MC4-Evo2 Branch Coupler 1 Male to 2 Female Ends

These waterproof Branch Connectors make it possible to parallel wire PV modules with original MC4 output cables (Original MC4 and Original MC4-Evo2). In order to parallel two solar modules together using the branch cable connector, you will need both this coupler and the 1 Female to 2 Male branch connector (see diagram below).

This MC4 branch connector is rated for up to 1500VDC. Maximum current is 50 amps (the branch connectors were previously rated for 30A at the time the video was recorded, so you will hear that in the video).

Note: Branch connectors must not be connected directly to panel receptacles of an inverter.
