Yup. I received approval and final certification this morning. Yay!

I also learned that they use an inaccurate rule of thumb regarding NEC 2017, 710.15(A). They said regarding my SLD that the ESS must provide less than or equal to the largest circuit breaker in the backup sub-panel. That is not what the code says. The code says, that the capacity of the ESS "...shall be equal to or greater than the
load posed by the largest single utilization equipment connected to the system." It is clear throughout the code book that "utilization equipment" is referring to the actual loads themselves and not the size of the circuit breakers in the panel. Clearly, such a restriction would be unreasonable considering Eaton, SQD, GE do not make AFCI breakers of values less than 15A, or breakers less than 10A in general. The wiring must be sized appropriately for the breaker, but the breaker value is not what NEC 710.15 is looking for. They almost had me convinced I was screwed using an IQ Battery 3T, because I can't get 6A breakers! Thankfully, I verified exactly what the code says and I'm good with my breaker ratings as long as my loads don't pull more than 5.33A continuous, or 6.33 surge at 240V.
