Eric, definitely what I had seen when we offgrid field tested the mppt- 80 in 2010 ! Totally bullet proof charger and the SQD disco shows there are 127 on the west coast for $115 HU361RB. Typically this is outside and protected where it belongs. It is fine next to the mppt if needed. Just do not land 600vdc in the PDP if you want code compliance and safety of the power system.
The newer Mppt-100-600 is just as robust.

All of our building wire is rated at 600 volts. If you segregate your OPCD, work neatly and bundle your various lead groupings I think it is perfectly safe. If one is real paranoid, you could rivet in some partitions or more simply, sleeve the 600 VDC leads in NMLT. I looked all through the documentation for the cabinets and no voltage rating is given. We cannot assume the rating is a limitation until we find one. Let us all know if you are privy to this detail. I would not hesitate to integrate the 600 volt rated Conext branded charge controllers into Conext branded BOS cabinets as long as the workmanship is good.

Do you want that in a PDP with your 48Vdc and 120/240vac? I do not believe it to be UL listed for 600vdc in there, and so you are breaking some pretty big rules here. I do not post much anymore here. Keep 600vdc out of the PDP and for Offgrid we always want high reliability. Just good design practice!
