Solis alarm 1017: Abnormal grid frequency
Solis alarm code 1017 usually means the inverter has detected abnormal grid frequency. When this happens, the inverter may temporarily stop exporting power to protect the solar system and comply with grid connection requirements.
Alarm code 1017 may appear as:
- G-F-FLU
This is usually not an internal inverter fault. In many cases, the inverter is responding correctly to frequency instability or abnormal conditions on the electricity network.
Abnormal grid frequency can sometimes occur due to temporary network disturbances, local grid instability, supply and demand changes or issues affecting the grid connection.
Let e-Solar check your inverter and grid frequency
If the alarm appears once and clears by itself, it may simply be the result of a temporary grid condition. The inverter will usually continue monitoring the grid and resume operation once frequency returns to a safe operating range.
If Solis alarm 1017 keeps returning, it is worth having the system checked. Our Perth-based solar team can inspect the inverter, review system settings and help determine whether the issue is related to grid frequency, inverter configuration, AC cabling or wider network conditions.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
- Your inverter model, if you know it
Do not open the inverter or attempt electrical testing yourself. If the issue is persistent, a qualified technician may need to review grid frequency data, inspect AC wiring and determine whether the issue originates within the property or the wider electricity network.
