Dave:
I have never been questioned about one of these interlocks by an inspector. I am prepared for it: · I can show a similar, factory built, approved interlock. · I can remove the interlock and demonstrate that even if the interlock falls off, turning on all circuit breakers simply makes the inverter system shut down immediately. There is no risk to life or property. If the installation will be inspected I polish up the interlock a bit more than usual and I may paint it. The bright cold galv. gives them a nice look. Or I have a bristle disc that gives a nice swirl finish. I added a close up to the article just now with the swirl.

I like your interlocking system, especially for when you need to run a load panel that is >100A. Have you ever had an inspector give you a hard time about making your own interlock, rather than using something listed?
