In February I updated Firmware on my 2 - 280AH indoor batteries as well as my 6000XP.
So far very happy with the changes but I have noticed something strange in the monitor system regarding the SOC.
Prior to the updates, when my SOC reached 100% it pretty much stayed there. Now, shortly after reaching 100% it dips to 99% for a little while and then back to 100%, then shortly after dips down to 99% again.
Before Updates:
After Updates:
Is this because of the new logic in the batteries that recalculates SOC for small load draws?
Is anyone else seeing this?
Any suggestions?
Thanks,

Sometimes the easiest solution is the best solution.
Sometimes not.
Yes! I am seeing this same behavior on the same setup ... (2) 280Amp Indoor Batteries and a 6000XP ... latest firmware on both the batteries and the inverter. I did not have this behavior prior to the battery firmware updates.
I looked at the data logs and it seems the batteries are discharging at ~0.9Amps (while there is available solar!!) ... the discharge forces the batteries from 100% to 99% and then the available solar charges them back to 100% ... this repeats until there is no more available solar (sun goes down) as far as I can tell.
The maxChgCurrent (BMS Limit Charge: on the monitor) seems to always be at 14A as well.
Not exactly sure but might be related to one of these things ...???
That is what I was think as well. It is a bit disconcerting seeing the change in monitoring methodologies.
Hopefully EG4 can chime in tell us if this is the new norm or if there is something we can do?
Thanks,

Any thoughts on this???
2 sets of screenshots ... Solar charged batteries to 100%, then solar cutoff but battery discharging at 0.7A ... will do this until batteries get to 99% then solar will charge batteries back to 100%.
Thinking the bouncing between 99% - 100% SOC is not a good thing??
I can share station name / serial number as needed.
Thank you.
99% to 100% ... discharge at 0.7A even though solar power is enough to offset consumption.
Back down to 99% and charge back to 100%
