[RE-wrenches] "Qualified solar electric property"? RE: battery storage limitations

[Kirk Herander]

Hello Howie -
Unrelated to tax code,
You had a question on Jerry's response referencing battery storage
limitations.

NFPA 855 (referenced in the 2021 NFPA 1 Fire safety rules), does put rules
/ limits on residential storage kwh size and layouts, amongst other things.
An 80kwh storage limit is mentioned here.
check out this link:

https://www.mayfield.energy/blog/fire-codes-and-nfpa-855-for-energy-storage-systems

This blog gives a good summary and history of both NFPA and IBC
requirements in the newest versions. Note Vermont is still working off NFPA
2015 for state-permitted commercial work, so the restrictions should not
apply at this time. That is of course unless a local municipality adopted
2021 on their own, which is how roof access pathway requirements came to be
in many VT towns for residences, first required in NFPA 2009 or thereabouts.
