Wanted to say thanks to everyone who gave input and guidance on my system. Had it approved last week and am really happy with the outcome. Planning on buying a Kia Niro EV this weekend to make use of the extra power. I have a 32A charger arriving today for it.
Specs:
24 Canadian Solar 330W 60-cell panels
Enphase IQ7 Microinverters
Enphase Combiner
Enphase consumption meters
Ironridge XR100 rails
QuickMount PV Tile Replacement Mounts
Quickmount PV conduit penetration tile replacement
Hardest part of the install was all the tile replacements. That took me about 3 days to finish. Also had to order extra Quickmounts, because the plan I drew up on paper didn't quite work out due to joist location under the tiles. So I had to shift some of the locations for mounts, which made me exceed cantilever specs. In the end, I like the Quickmount system. If you can design your system to have all the mounts in the same column, it makes things go easier. Just remove the whole column of tiles, from top to bottom, then start at the bottom and work your way to the top.
10ga THWN-2 in the conduit. 8ga Romex in the attic. I used 8ga as that was the ground size required, so I didn't have to run a separate ground. 8ga from combiner to disconnect to MSP.
I added a ground rod, which should have been good to code when combined with my water pipe ground. But, the first inspection failed, the inspector wanted a second ground rod and an irreversible crimp on the ground rod wire to the ground wire coming in from the solar, even though they were both connected next to each other at the bus. Didn't argue with the guy, just said, sure no problem. Second inspection he hardly looked at it and passed it.
Spent about $15k, so after tax credits, the system will have cost just under $10k for everything, including permits and whatnot. Pretty happy with that price.
If I were to do anything different, I would have used the IQ7+ instead of the IQ7. I would have less clipping and it only would have cost another $360. Oh well.
Again, thanks for the help of everyone on the forum. This forum was an excellent resource during my planning!
