sometimes I find in the early morning, after the night discharge, a situation with unbalanced batteries and some batteries well below 20%: Could it be a problem?

For example today I have had: The max difference happen during the charge
-
Since the last 3 batteries had the procedure from a technician to clear the EEPROM (to reset the fault). After the reset I saw that the SOC was changed immediately (about 10%) and the technician told me that the correspondence of voltage and SOC is back to normal

no the battery have different age and also different fimware: Battery 1: FW V2.2 new chip ( age 1 month) Battery 2: FW V2.2 new chip ( age 1 month) Battery 3: FW V2.2 new chip ( age 1 month) Battery 4: FW V2.8 old chip ( age 2 years ) Battery 5: FW V2.8 old chip ( age 2 years ) Battery 6: FW V1.8 new chip ( age 5 month) The master have positive connected to the inverter + Tha last battery (n°6) have negative connected to the inverter - I try also to maintain the batteries connected toghether but not connected to the inverter for 6 hours to have a idle situation. When batteries reach the idle status I check the SOC but was different. Also I've seem that that this SOC differece non remain every time the same but in same case the different is 1-2%, specially in the evening when no big load or solar are present.

Hi, I have had many problem of Over Voltage and after replace new batteries I tried to monitor the situation. I see that during the charge/discharge cycles the SOC values of the batteries are never the same SOC values but there is often a difference of 7/10%: I would like to understand if it is normal for the batteries to have a different SOC value even if the cells voltage are identical? The system consists of 6 US2000C pylontech batteries. Does this behavior happen to you too? Is there a way via commands sent to the battery to have a soc value corresponding to the voltage value? Thank you in advance

New software for Inverter/Pylontech monitoring and control

Hi, I use MultiSIB software but I'm only able to see the data from batteries. I don't see any inverter data. Can someone help me understand why? I'm connected to the console port of the master battery Thank you

Hi, I have a new US2000C battery (with a new chip) and the firmware installed is v2.2. I knew the latest was v1.8 but probably Pylontech has released a new firmware. Since I want to align all my batteries, does anyone have more information and where I can download this firmware? Thanks
