If your libbi displays Code 161 / W10: GFCI Over, this means that the inverter's ground-fault protection (GFCI) has been triggered.
What does this mean?
The libbi inverter includes built-in ground-fault protection to detect unsafe electrical conditions, such as unintended current leakage to ground. If this protection is triggered, the system will display Code 161 / W10: GFCI Over and may temporarily stop supplying power to prevent damage, electric shock, or fire hazards.
Troubleshooting Steps
- Reboot the inverter and then the libbi controller.
If you no longer see Code 161 / W10: GFCI Over, there may be an issue with the Solar PV or backup circuits.
If you libbi still shows Code 161 / W10: GFCI Over.
- Isolate the Solar PV and backup circuits.
- Reboot the inverter
