Single Phase 240 Volt Inverters on Two Legs of 208 3 Phase

If I am wanting to use 134 kW of PV on a 208, or 480, 3-phase system, is it possible to back feed through the 208/120 Y secondary, with one group of inverters feeding A-B, another group feeding B-C, and another group feeding C-A? Or, will it require feeding each inverter on A-N, B-N, and C-N?
