This is why I don't like J-boxes.
You could wire panels in series with MPPT controller and scrap the J-box, though you would still need some fitting for #10 cable through the roof (if there is no fridge vent on the roof).
Yep, no roof fridge vent. Fridge is in the slide, so it has a wall fridge vent, seen at the beginning of the video as I walk by the slide.
The J-box serves as a weather tight termination point over the hole in the roof, where the installer removed the cheap factory roof connector (which had undersized wire). Well, it was weather tight until I monkeyed with it two years or so ago.
The camper spends most of its time under cover, so what water did get in the box was never enough to get in to the ceiling.
