To conduit... Or not to conduit...?
Ok, I'm piecing together my solar stuff. I have a combiner box and mc4 cable enroute, I actually have enough room in the fridge vent topper to place a sealed box in there... Panels to combiner...

I'd opt for conduit. I used flexible non-metallic for brake wiring and it's OK but if I was doing it again, I'd use PVC. I have one underside battery bank run through 1 1/2 ABS but that is overkill for your run. I have two #1 AWG cables, the battery temp wire, and two #14 THHN in the ABS pipe. Liquatite is probably the best conduit, the stuff is darn near indestructible.
