Don't waste $200 on these *um* orange ones. These MC4 connectors crimp perfectly and won't break (alone or in a jar). I used a colleague for a while (same pair but a few years ago) and when he asked why I shouldn't just buy my own I said because I can't afford a $200 hand tool which he laughed at and sent me a link to them. Now they never leave my belt.
