MC4-Evo2 Branch Connector - 1 Male to 2 Female
These waterproof Y-connectors make it possible to parallel wire PV modules with MultiContact output cables (MC2/MC4/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/coupler is rated for up to 1500VDC. Maximum current is 50 amps (the couplers were 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.
