The SBC-2 Branch Connectors are used to connect two or more solar panels in parallel to increase the current output at the same voltage.
Each Branch Connector has 3 branches - two on the one side & one on the other. The branches could be "male" or "female". The construction of the branches is similar to the construction of the MC4 connectors. In a branch connector, all the 3 branches are internally connected in parallel.
