What does IsolationErr mean on my Afore Inverter?
If your Afore Inverter displays IsolationErr, it indicates low insulation resistance. Check the resistance between PV(+) and ground, and PV(-) and ground, ensuring it's greater than 2MΩ.
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.
What to do if my Afore BNT003KTL 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.
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 does IntFaultD mean on my Afore BNT003KTL Inverter?
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 does IntProtectR mean on my Afore BNT003KTL?
If your Afore Inverter displays IntProtectR, it indicates DCI circuit protection. Turn off the AC and then the DC circuit breaker, then restart the inverter. If the problem continues, replace the control board.
What does IntProtectA mean on my Afore BNT003KTL Inverter?
If your Afore Inverter displays IntProtectA, it indicates bias current protection. First, turn off the AC and DC circuit breakers, then restart the inverter. If the problem persists, consider replacing the control board.
How to resolve IntProtectC error on my Afore BNT003KTL Inverter?
If your Afore Inverter displays IntProtectC, it indicates inverter current protection. Turn off the AC and then the DC circuit breaker, restart the inverter, and check that each phase's AC voltage is correct via the LCD.
What should I do if my Afore BNT003KTL shows IntProtectG or IntProtectI?
If your Afore Inverter displays IntProtectG or IntProtectI, it indicates a bus voltage protection issue. To resolve this: 1. Check the AC output wiring is well connected and uses stranded copper cable. 2. Verify the PV array configuration is correct. 3. Ensure the voltage difference between BUS+ and BUS- is not too high.
What causes IntProtectQ on my Afore BNT003KTL 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.
