What specific UL listing(s) are they requiring? Around these parts it's been UL 9540 for all AHJs, and some requiring that even for lead-acid, despite the IFC exceptions and so few listed products (the IRC now seems to require UL 9540 even if the system is not grid-interconnected). UL 9540A is not an actual listing but an active fire test, results of which can be used to gain their UL 9540 and/or allow smaller offsets between each ESS unit and from windows, doors etc if their individual UL 9540A testing results allow that.
