yes supply side. I thought a was clear in saying the meter pedestal was triple lugged and first breaker is in each loads panels and first solar disconnect. I got two, one in garage and other by meter. i heard a rumor that someone in California was randomly slapping disconnect boxes on the side of pge trucks!
so what happens if a fault occurs between my first breaker and the utility? transformer blows up, wires melt? I don't believe transformers have fuses.

Transformers may indeed have a circuit breaker. But this is pretty off topic.

Be that as it may, I do not see where if your neutral had been bonded to ground in your PV AC disco it would have made any difference to what happened in the lightning strike.
 
The NEC is not a lightning protection code. For lightning protection comply with NFPA 780. Do not modify the NEC to provide "better" lightning protection since you will probably be making your system less safe for people. Follow 780 to add lightning protection on top of an NEC compliant electrical installation. NFPA 780 even has a section specifically for solar installations.

That's not what we were talking about.
