[RE-wrenches] UL batteries for open loop

[Dan Fink]

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.
