Thats interesting, thank you. I will have to look into these a bit more.
Does your utility have a set of standards for the generation that customers or design firms use?
I think I understand your question.
PG&E have a fairly easy to follow set of restriction and or standards as far as solar and genset.
What you see posted is from my enhpase (solar) monitor. You have to pay a little more to get consumption monitoring so not every solar setup has it, but it answers a ton of questions I had about my own use.
