Battery current draw

I have a 3.2 KVA 24 Volt Inverter I want to know how to calculate the maximum current being drawn from the batteries assuming its drawing the full 3.2 KVA
 
W=VxI

so I=W/V

So 3200/24 = 133.33 amps

However, that assumes 100% efficiency, so 150A is probably more like it.

So a LOT of current, VERY big batteries, and VERY thick cabling.
