It's not going to change any AHJ's behavior, but there's nothing in 705.22 requires a bladed disconnect versus a circuit breaker, and nothing in 705.22 refers to a 5' requirement.Some local jurisdictions including CPA were until recently ruling that each Powerwall needs a bladed lockable disconnect and citing 2017 NEC 705.22 as the reason.
This interpretation is still being used in at least one other jurisdiction, for any ESS more than 5' from the breaker it is served by. I am working on writing a white paper to describe this question, and get various smart people's opinion on the matter while I have access to a bunch of smart inspectors at the IAEI meeting.
