Vindeceptor ... you really got me thinking about this over lunch ....

Let's agree with your interpretation. That would mean that I could instal seven of the micro-inverter panels, backfeeding into six breakers in the panel- and not have any requirement to add a main disconnect, even if the 42-circuit panel was now full. (7 x 6 = 42).

After all, each of the micro-inverter units would be an independent service. Yet, none of the branch circuits would be powered only by a specific unit.

Add to that the main breaker, or the back-fed breaker on the Utility side, and you now need to flip EIGHT breakers to ensure that all of the branch circuits are dead.

I have a problem with this scenario. I can't speak for others - but I intend to have the next code cycle address this topic.
