Thanks @Hedges. My plan is similar -- run the shop on 120/208Y, but more conservatively with separate inverters. I appreciate that many of the members here are enthusiasts, experimenters, engineers who want to be on the leading edge of the inverter/charger wave. For a business, I'm a little more...
Thanks @timselectric. That's where I'm landing too -- it's existing building blocks, but perhaps in a new configuration.
Here's a picture of the proposed schematic and conceptual look of what the power system could look like:
I have a small cabinet-making business in MA/NH and am considering a property in NH. However, I will need 3-phase power (10-20kW loads & ~1MWhr/mo). 3-phase is about 1mi away and estimates are $90/ft.
I expect something similar to this...
