MC4 Connectors - I think they are bad
So, I had another post going months ago, but it was about finding the issue. I am pretty sure now my issue is the MC4 connectors... To review from before, I was having issues with no voltage regist...

I found when putting together my solar system that it is easy to not get the connectors pushed all the way (and locked) into the MP4. Then when you put the MP4s together (plugged into each other), it pushes the connectors back and causes a bad connection. On my solar installation I had one of the leads from the roof to the controller wide open. It turned out to be a connector on a plug (about right in the middle of the wire run) that had not been seated corrected and got pushed out the back of the plug. You may have a connector that is just barely making contact.
