If this is correct, then couldn't the OP simply wire his AC panel for two 120v and only use one of them for his bus?
Some people source both 120V phases on their split phase breaker panel from the same phase. Everything but double-pole breakers would work fine in that case.
Now people with tiny rigs or tiny/no inverter of course its not as practical, but at a certain system scale I think split phase is just easier to deal with overall. 50A RV input, capability to run both 120V and 240V appliances, residential AC panel.
If you want anything like a residential experience you're going lithium and split phase.
