Just installed a 48v 5kw Multiplus II GX with 4 Pylontech 2.4kwh batteries. After setup the batteries were charged from 70% to 100% the VRM is showing an alarm of High battery voltage. Battery reading 52.29V. Victron energy website shows Max Charge Voltage for this battery as 53.2V. HELP PLEASE
There are several threads on this forum about this topic.
Usually when Pylontech are new this can be an issue. The second one it they don't reach 100% SOC for a few days. It is not that the whole battery voltage is high it will be one or two cells in the pack somewhere that are higher. After a few days and some internal balancing that the pylontechs internal bms system should sort it out.
If it does not then a firmware upgrade I think on the batteries may be the answer.
It has been a while I hope it has sorted itself out already.
