Robin had a comment on the breaker issue...
I'll just copy and paste since he says it better than I can for this
kind of stuff.

Square D breakers are thermal breakers and are never used on PV
combiners. I am not familiar with any solar applications where thermal
breakers are used on a r

Hydraulic actuated breakers like the Classic Heiniman GJ,used in off grid
battery based systems ( now made by Carlon and Airpax, since Henimans's
patent ran out) it is very critical that they be used in the vertical
position as is marked on the breaker's chassis. I know this from
experience

Square D Disconnects
If the box is NEMA 3R, it needs to be mounted vertically to shed
water. If it is a sealed NEMA 4X rated unit, it can be mounted at any angle.

Bob O..thank you, you got to the heart of my original questionI am
not questioning the OCPD ratingsjust the can mounted at a slope
equivalent to the roof slope.Typically if we have rooftop OCPD they are
high voltage fuse holders and fuses or the Outback and Midnite solar
breakers...
Dan,
I think this thread applied not to OCDs but to an unfused 600VDC disconnect can
mounted on a roof which is less than vertical.

The "trip" mechanism within standard thermal over-current protective devices

15 degrees off of vertical is my understanding for standard RBs. So no,
can't do that. Cheers good friend.

Hi Folks!!!
Anyone aware of minimum slope requirements for Square D 321RB
disconnectsCan they be mounted on rails parallel to the slope of the
roof like Outback and Midnite solar combiner boxes(down to a 3/12 pitch)
I can't seem to find any notes stating the limitations in manufacturer
