[RE-wrenches] Stackable Battery-Based systems complying to IEEE 1547-2018 standard

[Mac Lewis]

Hi Wrenches,

I am working on a design for an all-electric home whole-house backup.  The
utility is requiring either an inverter listed to IEEE 1547-2018 or utilize
an effective grounding transformer with associated relay control system.
Im unclear whether the grounding transformer is on the customer side or on
the utility side, but I'd prefer to avoid this if possible.

I probably need ~20kW of continuous backup in this case.  I prefer to have
everything stacked if possible, but I may be able to split up my critical
load panels.

Has anyone worked through this issue?  I was planning on Sol-Ark but they
don't comply with the IEEE 1547-2018 quite yet.  I'm open to suggestions.

Thanks
