Have you tried disconnecting AC In wiring since there was no issue prior to that? Have you tried dropping back to running each inverter individually (not in parallel)? You could try disconnecting PV and run on battery only, and try disconnecting the battery and run on PV only. At this stage, it's trial and error.
Update -
Disconnecting Battery and running AC + PV = Fault goes away operates normal (with the exception of 27/27 low bat voltage bat open)
Disconnecting AC and running BAT & PV = Fault goes away operates normal
Running AC + PV + BAT = Faults...
Seems like there is something conflicting with BAT & AC

I know it's more work, but you could try and set it up with only one inverter individually (not in parallel) and see if you get the same results from each inverter. You never know but you might find that there's a problem with only one of the inverters. You might need to limit the loads a bit for the one inverter.

There is new firmware that addresses multiple issues dated 3-9-2025. CBCC-1900E0F
Got resolved, mine was a firmware issue. The tech at EG4 got R+D involved and they wrote a firmware specifically for this issue. He was patient and helpful.
***Update (kind of...)***
Spent several additional hours (March 11) on the phone with EG4 tech support/R&D to no avail. He suggested starting a RMA with the vendor. Ended up sending both units (shipped March 14 / CC received March 18) on my dime back to Current Connected to "expedite" the process and get back up and running. Everyone has been very helpful but this is now a month and a half between tech support and CC having my inverters. I was informed March 28th that a replacement will be sent but nothing has shipped. Was told today that they are "waiting on authorization". Getting getting frustrated... Would really like to wrap this up with a happy ending but losing faith.

Which firmware resolved the issue for you? I looked on EG4 website and could not find any info on the latest firmware. Did they pass on anything to you that you can share?

They released a firmware specificity for this problem and then pulled it because of problems
Has this been resolved? Did your new unites ship?

Oh, thought you had a problem similar to OP
Not yet!
Going to build out a system this fall (hopefully if the prices do not get jacked up)
