SMA Solar Technology AG
Operating manual STP110-60-BE-en-16 71
Explanation:
The AC output current exceeds the permissible upper limit of the inverter.
Corrective measures:
• Wait until the AC output current is within the normal range again. In general, the inverter is
reconnected to the supply grid when the AC output current is back within the normal range.
• If the fault cannot be rectified using the indicated corrective measures, contact Service.
12.2.6 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.
12.2.7 Event 009 (Sunny Portal: 502)
Event message:
• Grid underfrequency
Explanation:
The grid frequency is below the permissible lower 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.
