I have a 12000XP with two indoor batteries and no solar.  AC Charge Battery Current(A) is set to 40A.  The system is used as a battery backup with grid pass through normally powering the load.  I would expect a much high charge rate.

SOC 66%
From grid: 2744w
To batteries: 2118w
Load: 454w

I think I just found my answer but would like confirmation.  AC Charge Battery Current(A) set to 40A is 40A @ battery voltage and not 240v.

You are correct. For AC charging, multiply the amperage you’ve set by the battery’s voltage. This will give you the number of watts your batteries will be charging at.
