• AFCI FaultcriticalCall your installer

  Manual (PDF)

  AFCI module detected a failure

  Likely cause

  AFCI self-test is abnormal or an arc occurs on the PV terminal of the inverter.

  What to do

  If it is the first time this problem has occurred, clear arc fault by App and restart the inverter. If the problem persists, check whether connectors or cables in a PV system are improperly connected or damaged.

• Back-Up Over Loadcritical

  Manual (PDF)

  Back-up side is overloaded

  Likely cause

  Total back-up load power is higher than the back-up nominal output power

  What to do

  Decrease back-up loads to make sure the total load power is lower than back-up nominal output power.

• Isolation FailurecriticalCall your installer

  Manual (PDF)

  Ground insulation impedance of PV string is too low

  Likely cause

  Isolation failure could be caused by multiple reasons like the PV panels are not grounded well, DC cable is broken, PV panels are aged or surrounding humidity is comparatively heavy.

  What to do

  Use a multi-meter to check if the resistance between earth & inverter frame is close to zero. If it's not, ensure that the connection is well. If the humidity is too high, isolation failure may occur.

• Over Temperaturecritical

  Manual (PDF)

  Temperature inside of the inverter is too high

  Likely cause

  The inverter's working environment leads to a high temperature condition

  What to do

  Try to decrease surrounding temperature. Make sure the installation complies with the instruction on inverter user manual. Try to close the inverter for 15 mins, then start up again.

• PV Over VoltagecriticalCall your installer

  Manual (PDF)

  PV voltage is too high

  Likely cause

  The total voltage (open-circuit voltage) of each PV string is higher than the max DC input voltage of the inverter.

  What to do

  Check if PV string Voc is lower than Max PV input voltage of the inverter. If Voc of PV string is high, please decrease panels to make sure Voc is within the max DC input voltage of the inverter.

• FAC Failurewarning

  Manual (PDF)

  Grid frequency is not within permissible range

  Likely cause

  Inverter detects that the grid frequency is beyond the normal range required by the safety country

  What to do

  Make sure the safety country of the inverter is set right. If FAC failure only appears a few times and is resolved soon, it should be caused by occasional grid frequency instability.

• Utility Losswarning

  Manual (PDF)

  Public grid power is not available (power lost or on-grid connection fails)

  Likely cause

  Inverter does not detect the connection of grid

  What to do

  Check (use multi-meter) if AC side has voltage. Make sure grid power is available. If all is well, please try to turn off AC breaker and turn on again in 5 mins.

• VAC Failurewarning

  Manual (PDF)

  Grid voltage is not within permissible range

  Likely cause

  Inverter detects that AC voltage is beyond the normal range required by the safety country

  What to do

  Make sure safety country of the inverter is set right. Check (use multi-meter) if the AC voltage (Between L & N) is within a normal range (also on AC breaker side).
