What to do if my Afore BNT020KTL Inverter shows GFCI.Err?
If your Afore Inverter displays a GFCI.Err message, it indicates a ground leakage current is high or the PV(+) or PV(-) is earthed. To resolve this, first check the AC output wiring and restart the inverter. If the issue persists, inspect the PV array wiring.
What causes IntProtectQ on my Afore Inverter?
If your Afore Inverter displays IntProtectQ, it indicates DCI protection. Check that the PV array configuration is correct. Also, verify that the voltage difference between BUS+ and BUS- is not too high.
How do I resolve IntFaultG error on my Afore Inverter?
If your Afore Inverter displays IntFaultG, it indicates a high DCI. Check that each PV array's configuration is correct and verify that the voltage difference between BUS+ and BUS- is not too high.
What does IntProtectP mean on Afore BNT020KTL Inverter?
If your Afore Inverter displays IntProtectP, it indicates a frequency fault protection. When the grid frequency returns to normal, the inverter will restart automatically.
How to fix IntFaultB on Afore Inverter?
If your Afore Inverter displays IntFaultB, it means the bus voltage is out of range. Check that the PV input voltage does not exceed 900Vdc per channel and ensure the AC output wiring is well connected.
What does IntProtectN error mean on my Afore BNT020KTL?
If your Afore Inverter displays IntProtectN, it means there is an inverter over current protection. When grid conditions return to normal, the inverter will restart automatically.
What does IntFaultD mean on my Afore BNT020KTL?
If your Afore Inverter displays IntFaultD, it indicates a software over current fault. Check that the PV array configuration is correct. If there are fluctuations on the grid, wait for it to return to normal; the inverter will restart automatically.
What causes IntFaultE on my Afore Inverter?
If your Afore Inverter shows IntFaultE, it indicates an over current fault. The inverter will automatically restart once the grid returns to normal.
What to do if my Afore BNT020KTL displays GridF.OutLim?
If your Afore Inverter displays GridF.OutLim, it indicates the grid is fluctuating or the grid frequency is outside the set range. Once the grid returns to normal, the inverter will restart automatically. Verify that the inverter frequency setting range is correct and ensure the AC output wiring is securely connected.
Why does my Afore Inverter show GridV.OutLim?
If your Afore Inverter displays GridV.OutLim, it means the grid is fluctuating or there's a voltage unbalance between phases. The inverter will automatically restart once the grid returns to normal. You can also check each phase's voltage via the inverter LCD.
