Indoor micro inverters

Replacing roof. Considering solar power system while I'm at it.

Generally like the micro inverter approach, although mounting them on/with the panels is not ideal. Harsh environment for the electronics and somewhat difficult to replace.

Yes, I know most of the micro inverters come with a 25 year warranty. I also know designing and verifying the electronics actually live this long is a daunting task. 25 year warranty possibly a figment of the marketing department.

So my question is, is there a reasonable way to mount the micro inverters indoors? Seems like the big issue is cabling.

Yup, this is exactly what I did. Though I think it's debatable whether using the top rail and pivoting up is easier than putting microinverter on the bottom rail and sliding the panel up higher on the roof, thus obviating the need to hold up the panel. I think I installed both ways. Haven't had to service yet.

I think because of the chimney effect of warm air, I would prefer positioning them at the bottom rails over at the top rails.

It won't comply with NEC for Rapid Shutdown if the devices are not within the array. To avoid putting them on the roof, build a ground mount.
