Event 008 (Sunny Portal: 503)

Event message:

• Grid overfrequency

Explanation:

The grid frequency exceeds the permissible upper limit of the inverter.

Corrective measures:

• Wait until the grid frequency is within the normal range again. In general, the inverter is reconnected to the supply grid when the grid frequency is back within the normal range.

• If the error occurs repeatedly, measure the present grid frequency and contact the local grid operator concerning solutions if the grid frequency is higher than the set value.

• Ensure that the protection parameters are set correctly.

• If the fault cannot be rectified using the indicated corrective measures, contact Service.
