Guys today my 2.5kw solar system all of a sudden cut out on a hot day while I was running a 2.0kw air conditioner.
I went to investigate and to my horror I found a MC4 connector completely melted through. Now to be honest I crimped these myself from connectors I got on Amazon for cheap. It’s also possible it got wet a little bit from a sprinkler. What could have gone wrong and what can I do better? I put a new connector on and the system is fine, but I was just really surprised. Do I need to put shrink wrap on these? Are they not allowed to be in direct sunlight? It’s a 95 degree day heatwave that this happened.
