SMA Solar Technology AG
Operating manualSTP110-60-BE-en-1674
Explanation:
The grid voltage is higher than the set conservation value.
Corrective measures:
• Wait until the grid voltage is within the normal range again.
• If the error occurs repeatedly, measure the present grid voltage and contact the local grid
operator concerning solutions if the supply grid voltage is higher than the set value.
• Ensure that the protection parameters are set correctly.
• Ensure that the cross section of the alternating current cable meets the requirements.
• If the fault cannot be rectified using the indicated corrective measures, contact Service.
12.2.14 Event 016 (Sunny Portal: not used)
Event message:
• Output overload
Explanation:
The configured PV array power is excessively high and is outside the normal operating range of the
inverter.
The inverter interrupts feed-in operation immediately after exceeding a threshold. When the fault is
eliminated, the inverter automatically reconnects to the utility grid.
Corrective measures:
• Wait until the value is within the normal range again.
• If the fault cannot be rectified using the indicated corrective measures, contact Service.
12.2.15 Event 017 (Sunny Portal: 1416)
Event message:
• Unbalanced load of grid voltage
Explanation:
The inverter detects an unbalanced three-phase grid voltage.
Corrective measures:
• Wait until the value is within the normal range again.
• Measure the current grid voltage. If the grid conductor voltages vary considerably, contact the
grid operator concerning proposals for solutions.
• If the voltage difference between the 3 line conductors is within the permissible range of the
local grid operator, change the parameter for the unbalanced load of the grid voltage.
• If the fault cannot be rectified using the indicated corrective measures, contact Service.
