Tried posting this in the beginners' corner, but I am guessing that perhaps wasn't the right place for it. Apologies if this comes across as spam.
After reading an earlier thread about NEC 2020 and DIY installs, I'm completely rethinking my storage plans. Definitely not going to be building my own LFP battery packs. (If I could and still meet code, I absolutely would. And I plan to have a detached shed specifically for batteries + inverter anyways for safety.) I have started to engage my local electrical inspector, who still needs to read up on the new rules. But I'm wondering what others are doing for NEC 2020-compliant batteries/"energy storage systems". I really want to stick with LFP if I can, but I also don't want batteries to break the bank. There do not seem to be very many options.
Looks like SimpliPhi got UL9540 certification this year for a couple of their storage solutions (link), but their batteries are only UL 1973 certified (spec sheet)
Also appears that Fortress eFlex 5.4 is UL 9540 certified (spec sheet)
The California Go Database (mentioned in another thread) has also been helpful in tracking down UL certified ESSs, but few of them look promising.
