Is 40A Fuse enough for SOK 24v (2 x 12v) 206Ah

As HRTKD says, if you have a 2000W inverter and 24V battery, current draw is over 83A. Probably up to 100A. So a 125A fuse would be appropriate (25% larger). Wire needs to be large enough for 125A, maybe larger to reduce voltage drop if a long run. Type of fuse matters, because a lithium battery can deliver quite a few thousand amps into a short.
