What causes IntFaultK error on Afore Inverter?
- MMelissa FloresAug 27, 2025
If your Afore Inverter displays an IntFaultK error, it indicates a bus voltage fault. To address this: 1. Check that the AC output wiring is well connected, using stranded copper cable. 2. Verify that the PV array configuration is correct. 3. Check the voltage difference between BUS+ and BUS- is not too high.
