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.
