Troubleshooting
8Fault codes
| Code | Meaning | Cause | Remedy |
|---|---|---|---|
| GeneratorVoltageImbalance OR GeneratorComBusPhaseDifferenceOOR | Generator was overloaded. | Generator breaker in IQ System Controller tripped, and the generator is disconnected. | The system will try to reconnect the generator in 5 minutes. You should: • Open IQ System Controller door, turn off the generator breaker and turn it on again. (When you open IQ System Controller, the generator breaker lever will not be in ON position) • Ensure you do not overload the system while the generator is running. |
| EnpowerGeneratorVoltHighTrip OR EnpowerGeneratorVoltLowTrip OR EnpowerGeneratorFreqHighTrip OR EnpowerGeneratorFreqLowTrip | Generator voltage and/or frequency out of spec while in generator mode and generator is connected | The generator gets disconnected | |
| GeneratorStartFailed | Generator not starting | The generator does not start as selected in user preferences. | Check if the generator 2-wire start/stop wiring to IQ System Controller is loose. Check whether the generator breaker at the unit was tripped (if so turn the breaker off and then on. Also switch the controller to the auto position), whether the generator is out of fuel, or the starting battery of the generator was dead. Contact your installer or Enphase customer support if the problem persists. |
| GeneratorStopFailed | Generator not stopping | Generator continues to run even though user preferences indicate it should have stopped. | Check if the generator 2-wire start/stop wiring to IQ System Controller is loose. Turn off the generator manually and contact installer or Enphase customer support. |
| GenTHDHigh | High Total Harmonic Distortion (THD) Measured THD is above 25% | Generator power output is not stable and having high THD (THD means total harmonic distortion, which is a metric to measure the power quality. If the THD is high, the performance of your electronics will be affected; for example, you may see flickering lights). |
Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Explosion | Battery short circuits | Disconnect the battery before generator set installation or maintenance. Remove all jewelry before servicing the equipment. Use tools with insulated handles. Remove the negative (--) lead first when disconnecting the battery. Reconnect the negative (--) lead last when reconnecting the battery. |
| Battery short circuits | Disconnect the battery before generator set installation or maintenance. Remove all jewelry before servicing the equipment. Use tools with insulated handles. Remove the negative (--) lead first when disconnecting the battery. Reconnect the negative (--) lead last when reconnecting the battery. | |
| Gas fuel leaks | Check the LPG vapor or natural gas fuel system for leakage by using a soap and water solution with the fuel system test pressurized to 6--8 ounces per square inch (10--14 inches water column). Do not use a soap solution containing either ammonia or chlorine because both prevent bubble formation. A successful test depends on the ability of the solution to bubble. |
