[RE-wrenches] Three-phase off-grid

[Jason Szumlanski]

Do they actually have 208v loads? If not, replace with 120/240 panel. Just a thought... Although a transformer would be required to use an existing 208v generator.

Initial projections (consumption measurement results not yet available) suggest 15-20 kW of PV and around 30 kW of inverter capacity. However, the generators and existing wiring are three-phase 120/208.
