I really don't understand what your problem with this arrangement is. How would this be different from a house on phase A-B installing an inverter and the next house on Phase B-C installing an inverter? Or, installing two single phase 240V A/C units in a three phase building? Electricians have no issue with installing single phase equipment in three phase buildings so why should small inverters be any more a problem. While it is always neat to install three inverters n a three phase configuration, 4,500 watts of imbalance is trivial.
