1What the error means
Grid over-frequency: the frequency exceeded the upper limit and the inverter stopped feeding in.
On the display or in the monitoring software it appears as Grid OF.
2Possible causes
- Grid frequency instability
- Operation on a generator or a weak grid
- Wrong country setting
3What to do
- Check the country setting and the frequency limits in the parameters.
- Note whether it coincides with specific hours or with generator operation.
- If the grid is stable and the fault persists, check the measuring circuit.
