If your libbi displays Code 163 / W12: Fan Fault, this indicates that there is an issue with the cooling fan in the libbi inverter.
What does this mean?
The libbi inverter uses an internal fan to maintain a safe operating temperature. If the fan fails or is obstructed, the inverter may overheat if it continues running without adequate cooling.
When Code 163 / W12: Fan Fault is triggered, the system may reduce performance or temporarily shut down to protect internal components. This is a preventative measure designed to avoid damage to the inverter.
Troubleshooting Steps
- Reboot the libbi Inverter.
- Reboot the libbi Controller.
If your libbi still displays Code 163 / W12: Fan Fault, please contact the myenergi Technical Support Team.
