Hello--this is the roof that will support 32 LG 330W panels with the integrated Enphase IQ6+ microinverters. I'll use S5 clamps plus railing to put the panels in portrait mode. I am going to use three strings(11+11+10 perhaps) and take those wires to a junction box in the upper row of the array(have any recommendation for a decent junction box that could fit under/attach to the railing?). I wanted to run conduit through the house to the area you see with the red circle. I would take the three circuits down the conduit, to the basement, back out to the outdoor wall to an Enphase IQ combiner box, then a single set of wires to a disconnect, then back into the house to the main panel. Grounding for the racking would be via bonding the panels, ground wire and lug across the railings, then down the side of the house to the ground rod in the ground. I know I don't really want to bring the ground for the racking into the house with the wiring for the 3 strings. Does this all sound reasonable? I appreciate any and all tips and comments.
