As I read your chart tell me please if I am reading it right. If I buy a 2,000 watt inverter and never use more than 1800 watts, I think I would be using 14 or even better 12 g wire. I got to this by dividing 110 volts into 1800 watts getting 17 amps. At <6 feet, the gauge wire is 14. Am I doing it right?
You need 1800 watts @ 12 volts which is 150 amps from the batteries to produce 1800 watts @ 110 volts which is 17 amps.
Big wire needed from the batteries to the inverter.
smkettner has it right
