I don't know the BMS in those units. It took me a while, But I found how to look at the logs in my JK-BMS and I was shocked to see how much detail it actually stored. Are you able to go in and see an event log in each of the batteries? I would assume the BMS has to store something like a temp sensor swinging that high to cause an error.
This is only a guess,
The other possibility is a data error between the BMS and the Inverter. Maybe a byte of data is lost, it could shift the data over and any data after a lost byte could all be wrong. Error checking should catch something like that, but I still see it on industrial control systems from time to time. Then on the next full transfer, the data is then corrected and it seems all back to normal. The device that sent the data has no idea the value was bad. The receiving device may see it as out of range, but it could see a value that makes it react to the wrong value, but it might not see it as an error. In your case, it just cut charging current because the battery was hot, but the value was still a valid but higher than normal temp..

I will try and dig into the bms software in the morning and see what I can find. Everything went right back to normal after that except the warnings won't clear from the inverters until I do a power off and reboot the batteries and inveters
Well I do believe I may have a problem with the Inverters or maybe Firmware issue. I disconnected the batteries from the system ( no Closed loop) Reset all equipment Rebooted the Inverters powered off batteries waited 10min. Everything came back up fine without BMS Communication no problems all day until 16:04 this afternoon. Another battery temperature sensor warning from the XW's. Which isn't even possible without any kind of sensor or closed loop.
I think I am going to go back to firmware 11 and see if that helps. Any other suggestions would be greatly appreciated.

Have you tried connecting the battery sensor that came with XW6848 to the battery. On my lead acid batteries I once had a bad sensor and once I replaced it, the battery warning went away. I understand the BMS is supposed to communicate but you could see if this helps avoid any more battery warnings.

When you updated firmware on the XW did you "reset all settings to factory" ?
Apparently, that's a important step that is easy to miss. It might be worth a try as part of your plan to roll back firmware.

Not totally related to this thread, but...
I have had 2 more emails up and back with Schneider about the oscillation issue. He wants me to record a video of the status page when it does it again, but of course, now it ha not in a few weeks. But he also recommended I roll back the XW-Pro firmware to 1.11 to see if that stops the issue. He has not mentioned doing the "reset all to factory" step. But I will do that if I do change the firmware. I am staying as is for a bit longer to see if I can catch the event again.

Hi,may i know your batteries SN code?
Well I think we have finally got to the bottom of this problem! I was on the phone with tech support and happened to notice that one inverter the master was reading 114.5 degrees F under the status page for battery temperature. Every other device was showing N/A.
