What size battery bank for large Inverter?

I am going to assume that the 230 vac is not 120/230 single phase 60 Hz. but just 230 vac 50Hz.
The inverters maximum rated output is 10,000 watts.
10,000 divided by 12 vdc nominal would be 833 amps.
This 833 amps is just not feasible.
This would call for nothing less than parallel 500 MCM times 2.
I have a few questions for you.
What size wire is feeding this inverter from the batteries?
Your batteries have a total of 550 amp hours at 12 vdc nominal, right?
At best this would give your inverter 6600 watts for 1 hour at 240 vac. Of course all of this is dealing with the absolutes of math. I n the real world you would only get a fraction of this. Probably about 80%. As amp hours get used up battery voltage goes down quick even with the best true deep cycle batteries.
