I'm putting in a 3kW system and have good enough access in the attack that I am thinking about wiring the home run down I to the attic, out the and down the exterior wall to the switch. Here is what I was thinking to do and I would appreciate feedback as to whether there are any issues with this plan:
1/ SolarDeck through-roof enclosure below the final Microinverter - I'm hoping I can run the female interconnect cable right into it so that it can serve as my junction/combiner box (single-string)'
2/ Romex into the attic - The Romex probable needs to be clamped so hopefully I can position the Solardeck in a way that a short run of plastic conduit lands near a diagonal roof member to mount a junction box (which will only be used for the clamp - no actual electrical junction).
3/ Romex continues to the soffit where I can position a junction box. Ideally an electrical junction here but I could strip off the Romex sheathing if an electrical junction must be avoided.
4/ metal conduit along the exterior wall down to the switch.
Is there are reason this woukd be a problem?
My biggest questions are about how to mount/clamp the Romex at the Solardeck and whether I can use an electrical junction to switch from Romex to different conductors at the junction box under the soffit.
