Good day,
Is there any issue by setting up several units of Quattros in three phase for an ESS system but with AC input from a single phase configuration?
This is because is intended to run three phase motors.
Regards.

This can be done by turning off switch as group when setting up the system, and connecting the grid to only one of the Quattros. The AC inputs of the other two Quattros would not be connected to anything.
The unit connected to the grid will pass through power to loads on that phase when grid is present. The other two units will always run in inverting mode, powering the loads on those phases from the battery bank.
Be advised that only the Quattro connected to the grid will charge the battery bank.
If needed you could supplement battery charging from the grid with an AC charger such as Skyla, etc.
Thank you @Kevin Windrem for your response. In my case there will be 9 units of 10kW considered for the design as shown:
In that case only three inverters will have the input connected and six will run as inverter?
