STATE 115STATE 115
AC frequency too high on phase 1
Behaviors
Grid conditions are thoroughly tested and as soon as they are again within the permissible range the inverter will resume feeding power into the grid.
Status Code Class 1
Class 1 status codes (state codes that start with a one, i.e., 1xx), pertain to anomalies detected at the inverter's AC grid interconnection, specifically parameters such as voltage and frequency. Before the inverter can commence operation, it must detect that the grid is within a ceratain range, for a predefined period of time.
Should the inverter identify the grid is outside these parameters, it will temporarily disconnect from the grid and cease production. Concurrently, the inverter will begin assessing the grid conditions per the stipulated monitoring period (e.g., every 5 minutes). If no further issues are detected by the end of this period, the inverter will automaticaly activate the GPIS SoftStart function gradually increasing its output power, in line with national guidelines, and resume feeding energy into the grid.

Solutions for this Error
Remedies
- Check AC breakers and switches are in the ON position. Check mains AC voltage and frequency at the inverter clamps (Qualified persons only). This error should automatically clear once the grid is back within an acceptable range. If the grid is within operating parameters and this error persists, the device may have an internal failure.
- If this issue persists, the next steps include inspecting internal inverter components and their cabling by a trained Fronius Service Provider to further diagnose this specific issue. Defective components or the device itself may need to be replaced.
