Hello! First time posting but I have had (2) 2Q series BMS for a while now, both running separate 48v 500ah systems. It seems at this point that either the batteries have haywire cells that the BMS seems unable to control or that something is off in the settings. I'll attach a couple Log photos as examples
The above system we will call STE. Frequently when charging from solar I have been noticing that the cells seem to be split almost 50/50 by voltage, as you see above, some are on the high end (3.6) which is my max allowed voltage and the others around 3.3-3.4. This often times has lead the system to get quite confused, thinking that the battery is nearing a full state (package voltage) when half the cells are still low and therefore stepping down the amount of power coming in from solar. It also often times gets the error you see here (cells differ more than threshold).
Here are some other examples:
