For my RV application, I have a transfer switch with both shore power (50A) and generator power (Onan 8kw) as input. The shore power is normal 2-phase 240V, while the generator output is 2 30A single phase circuits.
I don't need 240V in my RV - everything is 120v. Is there any reason I cannot connect each leg of the transfer switch output to a separate Multiplus inverter/charger? When on shore power, the 2xMultiplus inputs will be 180 degrees out of phase. While on generator power, they will be in phase.
At this point, I am not planning any passthrough loads - all loads will come from the inverters.
