Wiring/ Stacking Two XW's

Hope all is with with everyone here. Just in the process of building another complete off-grid system. Simple question: When stacking two XW's, what gauge copper wire should be used for the output of both inverters?
Each XW comes standard with a 60 amp breaker, so I originally thought, 120 amp capable wire after the staking kit bus bar. However after talking with an engineer, He said breaker and wire size is based on continuous max load. Also, He said that 100 amp capable wire is all you'd need on the output of two stacked XW inverters.
I calculated max continuous output of each inverter is 6800 watts X 2 (two inverters) = 13600 watts divided by 240 V = approx 60 amps?
He also suggested #2 copper wire on the output of the two inverters which is good for 115 amps.
I looked up #3 copper and I think its good for approx. 100 amps. Although both inverters will rarely be pushed to the limit, if ever, I want to ensure I use the appropriate size of wire for this stack.
Thanks for any insight and or suggestion anyone may offer.
Much appreciated, as always.
