Should I run 10 awg wire from the box down to the controller or bigger can't find uv protected wire in larger sizes

That's why I ran my 2ga out the bottom of the box and down thru the roof to the basement behind the washer and drier. Putting the heavyweight cable in grey Corlon conduit and across the roof to a protected location is also an option. Ten gauge cable for more than one panel connected in parallel is just too light.

Interesting how some folks reject real world experience in place of their uninformed personal opinions. Your choice... I just reported what really worked.
