Okay, how small of a connection would they have to restrict him to for me to be correct?

That much extra curtailment is a major problem. That much extra angle diversity hurts output. Batteries are a workaround for not being able to properly hook up the panels.

You'll have to do your own calculations based on your own site data.

Onsite BESS permits you to not only get by with a smaller hookup but also sell your energy at times when people are willing to pay for it.
