Tested the max charging on bypass today. I bumped both units to 120A on Setting 11 while on bypass/charge and placed clamp meters on both lines.
The units each throttled total 120V input amps drawn at 61A regardless of load I placed. Turning a Kobalt 1500W heat gun on while the line was measuring 61A draw led to a momentary (less than a second) blip of 68A, then immediate throttle at 60.5-61.0A.
So they are pulling back on battery charging amps when more pass thru amps are called for and doing it pretty fast. I did get a voltage sag from 117V to 113V when hitting the throttle. Our work computer UPS units didn't like that, my son reported they clicked to battery mode a few times for the 60 seconds I was at the limit.
This is good and means the 60A breaker is pretty spot on. I bumped both units down to 60A each on Setting 11 after the test. I don't need to charge at max rate.
I tracked temps. The breaker peak was 28.5C, open air wire peak was 22.8C and the 3/4" liquid conduit at the inverter AC Input was 23.5C max.
I've been running at 60A Setting 11 for 15min now and the breaker temp has come down to 23.5C. Clamp meter reports 54.8A to batts from 2P1 and 55.1A to batts from 2P2.

roughly 2kW and me turning the Kobalt 1500W heat gun on.
