Wrong battery reading from the Victron MPPT 450/100

Hello, I had until yerterday two 3500 W Pylontech batteries installed since my four 48v Pylontech US500 modules had to be taken to the technical service a few days after installing them and the readings were correct with the 3500W.


Yesterday we installed the 4 repaired modules with the new BMS changed and everything is working now. What happens is that the Victron MPPT makes an erroneous reading of the minimum voltage of the batteries. As you can see in the photo, it says that the minimum voltage today is 10 V and yesterday 17 V.


This is impossible since the entire installation would have been cut off and I have been observing it and the voltage is always between 49 V and 52 volts.


How can I correct this Victron reading error? Which may be?

Maybe the batteries are switching off.
