Hi Jason,
I haven't tried ordered through Enphase's store recently, but in the
past they have had those breakers available here:
https://store.enphase.com/storefront/en-us/enpower-breakers. They are
showing them in stock right now, but not sure if that's reality.
A workaround I've tried is using BRH220 breakers (which are 22KAIC). At
least some of them have a fastener hole for the hold-down kit. I don't
think they are listed as allowable model numbers in the Enpower manual,
however, depending on how particular your inspectors are.
Best,

Enphase Encharge requires bolt down breakers for backfed battery
circuits in the Engage Smart Switch. All ampacities below 60A require
the model number with 'B' at the end to get the required fastener hole
in the middle of the 2-pole breaker. 60-80A BR breakers all have the
hole already without the 'B' designation.
These seem to be hopelessly backordered under 60A. Does anyone have a
source? I noticed that Enphase has their own part numbers for these.
Maybe they have a stockpile of them somewhere. Any ideas?
