I have a Luxpower 12Kw inbound, it can do 120/240 split, or 120/208 (2 out of 3 phase legs). I happen to live in a community with a lot of multifamily buildings, so the distribution transformers are all 3-phase output At my single family, 200A residential service, 2 out of 3 phases are serving my home, with a "neutral". This is all fine for the Luxpower whole house 200A breaker capability. The problem arises when my generator, which is conventional 120/240 split phase, may need to be used to charge the batteries via inverter, and it will NOT be allowed to while the inverter is in 120/208, 2/3 phases mode. What setup can I use to parallel charge my battery bank using generator supply without confusing my inverter?
