|List Price:||US$15.00 EACH|
Solar panels are often supplied with wire tails having waterproof MC-4 connectors. While these can always be removed and connections made in a junction box, having the appropriate connector is easier and maintains the water proofing.
For connecting panels in parallel, the branch connectors are used. They will connect two incoming lines to one outgoing line. They come in pairs, one for the positive line and one for the negative line.
