6000 BTU is 1758 W (6000 x 0.293 =1758).
700 W is 2400 BTU.
The Dometic a/c we have draws around 1750 W with a maximum of around 1.4 kW from solar so we are drawing around 500 W or more from the battery suite. I believe that it is supposed to be 13,500 BTU but this is 4 kW.
We have considered getting a small a/c that draws around 750 W. The Aussies apparently use the semi-split a/cs. The semi-split a/cs are inexpensive (sorta') but require some invasive modifications.
So I guess we shall just avoid hot areas as best we can.
