Yes. It does have a 2000 watt surge capability.

If I find that the 100 Amp unit trips repeatedly and is too weak, I have some 150 Amp ANL fuses and a fuse block stored in the camper while I see how the inverter acts. It wouldn't be difficult to swap out the ANL holder for the breaker. If I get tired of pulling the fuse to eliminate the inverter's parasitic draw, I'll pick up the 150 Amp breaker. Hopefully, the 100 Amp breaker will be OK. Those suckers are expensive.
