Unfortunately insisting a neutral from the inverters will deem the inverters incompatible with 240V High Leg Delta if it’s a 120/240V output from the inverter. Reason being is because the inverters can't match the high leg voltage of 208V L-N on Phase B, only 120V L-N for Phase A & C, therefore risking damage to the existing electrical system. We've seen success with the use of inverters that output only 240V L-L , that way you never touch the L-N voltages.
