Error Code 42 "BMS Overvoltage"

Product Discussion BLUETTI AC Series
#1

Charged my Ac200p for the first time, and now it shows the fault code 42 whenever I turn it on.
After draining the battery completely the unit also displays that it’s 100% charged even though it is not and doesn’t charge from the wall adapter.
I do believe the BMS in this unit is completely defective.

Has anyone else run into this issue?
