[RE-wrenches] MC4 Y Connectors

[penobscotsolar at midmaine.com]

We use them commonly on our Caribbean off grid installations. It is an
efficient and code compliant way to cut down on wire runs and number of
breakers in a combiner box while still providing the requisite protection.
We never combine more than two strings.
