If your libbi displays Code 165 / W14: BMS Discharge Over Current, this indicates that the Battery Management System (BMS) has detected an overcurrent condition during battery discharge.
What does this mean?
The BMS is responsible for monitoring and protecting the battery pack from unsafe operating conditions, including overcurrent, overvoltage, and under-voltage.
When the battery discharge current exceeds the safe limit defined by the BMS, the system triggers Code 165 / W14: BMS Discharge Over Current to protect the batteries and inverter.
