I agree that it may not be powering the house now, but it they easily 'trigger' it because a battery system will have a "transfer switch" to disconnect from the grid (so they can use the system during power outages). Even when there is grid power (such as now), they can hit a manual transfer switch (including a manual way to activate an automatic switch) to disconnect from the grid and use the solar panels until the battery is drained.
Maybe if the transfer switch is manual, it might be allowed. I had thought of that, but the problem is that if the homeowner is at work and the clouds come in, the a/c and fridge go out if there is no one at home to operate the manual transfer switch. And I suspect that even if the transfer switch was manual, it will be locked and tagged out by the installer until the utility inspection. An installation mistake could take down an entire neighborhood.
And this is largely irrelevant, since we are talking about "completion" instead of "in service" (for a residential system).
