MC4 solar connectors (bulk):




MC4 connectors are sold in bulk. "MC4" seems to be trademarked and not often used, so search instead for the
term "solar connectors" to find listings. Not all connectors are good quality - I got a batch with a crimper
that turned out to have poor tolerances and the O-ring didn't seat into the other connector. Also, you'll want
to make sure you get a pair of MC4 tools to tighten the end caps and especially for uncoupling the MC4s.
