Where to Buy MC4 Connectors

kelly

Does anybody have a good source for MC4 connectors? My 10 gauge UV stabilized wire is 1/4" outside diameter and some of the connectors I get through Amazon and eBay won't fit on such a large cable - some of them are real junk, too. The big solar retailers (like Northern Arizona Wind and Sun) don't seem to offer the loose connectors.

CThe typical recommendation is to to buy a Male/Female MC4 cable and cut in 1/2 to make your MC4 to standard electrical connections:

Just purchased some loose MC4 hardware, perhaps PM him and ask where he bought his.

I've never had a problem, though it's been a while since I didn't use 'use2' wire. They sometime come already compressed, likely you know, but they have a compression gasket in them. So if they have been tightened down, at all, you will need to loosen them to get the larger "PV Wire" with it's thicker insulation.
