MC4 Solar Connectors. Good & Bad ??
I know the MC4 parallel connectors are different in quality, because when one broke for no reason last year, the replacement was much heavier in the center section where it broke,
Now today I had the 2nd positive MC4 connector break in the threads that hold the cap over the strain relief. As before, they break for no reason,....altho I know using the panels as portable, they do get handled much more than if on the roof.
At any rate, replacing/installing MC4s is not my most favorite thing to do, so in both cases I just chopped the connectors off, and soldered the wire direct to the controller input wire. 3 panels on the roof now, 1 w/ connectors, 2 w/o. No more portable panels, just too much hastle.
But I was curious about the MC4s, anyone have any break ? Is there good, and better MC4s out there ?
