Fault |
Display |
Possible Actions |
| System | No Utility | 1.No grid voltage. Check the grid voltage by multi-meter. 2.Check grid connection, such as wire and connector to the inverter. 3.Check breaker between inverter and grid; if it is tripped, DO NOT CLOSE again, get an electrician to check the wiring and inverter. |
| Grid Fault | 1.Wait for grid power to return to normal. If the grid returns to normal, the inverter will start again automatically within 5 minutes. 2.Check the grid voltage and frequency by multi-meter. Make sure grid voltage and frequency meet the specifications. 3.Contact your inverter service representative to discuss adjusting the operating range, if permitted by the electricity provider. |
|
| Impedance Fault | 1.The grid impedance is higher than the permissible value. 2.Wait for grid power to return to normal. If the grid returns to normal, inverter will start again automatically within 5 minutes. 3. Check the wires between inverter and grid. For high impedance connections, get an electrician to increase the wire size. 4. Contact your inverter service representative to discuss adjusting the operating range, if permitted by the electricity provider. |
|
| Isolation Fault | 1.Check the impedance between PV (+) & PV (-) and earth ground. The impedance must be larger than 8M . If the impedance is low a ground fault may exist in the PV array or wiring. Contact your PV array service provider or electrician. 2.If above actions do not fix the problem, the isolation detection circuit may be faulty. Contact your inverter service representative. |
|
| Ground I Fault | 1.This is caused by too high ground current. 2.Disconnect the inverter from the grid power. Check the AC wiring and connection system. 3.After the cause is cleared, reconnect the grid power. Check the status of the inverter. 4.If above actions do not fix the problem, the GFCI circuit may be faulty. Contact your inverter service representative. |
|
| Inverter Failure | Over Temperature | 1.The internal temperature is higher than specified normal value. 2.Reduce the ambient temperature by shading or ventilation improvements or move inverter to cooler place. 3.If this is not effective, a temperature sensor may be faulty. Contact your inverter service representative. |
| PV Over Voltage | 1. Check the PV open-circuit voltage. This should be less than 500VDC. 2. If the PV voltage is much less than 500VDC (e.g. <430V), measure the DCV by multi-meter, compare the readings on meter and LCD. If the readings differ by >5%, contact your inverter service representative. |
|
| Device Fault | 1.This is caused by an inverter malfunction. 2.Disconnect PV (+) or PV (-) from the input, start the unit again. 3.If it does not work, contact your inverter service representative. |
|
| Consistent or Mismatch Fault | 1.This is caused by inconsistent values between the main (master) and redundant (slave) controllers of the inverter. 2.Disconnect PV (+) or PV (-) from the input, start the unit again. 3.If this does not work, contact your inverter service representative. |
