And I think the Schneider XW supports up to 66v? No?
Not selling ever. Grid support = puling power from the grid to support load base on battery voltage. So let say i set it at 47volts. The inverter would only invert dc from battery yo aupport my loads if battery is above 47volts. The higher voltage mean it will invert more and more up to 90% of my load. What worrying about is that the battery would not have enough voltage room and it would drop below 47volts and it would not inverting even when battery is still full. If this happen it would pull all power from grid and not inverting.

What do you think of using the 2x 24v and tie it to the 48v to make it 15s? Placing the battery in ways that i could use half of that 24v module but without actually separated them cells.
