11.2 Events: Information, Warnings and Errors

During operation of the PV system, events may occur which can refer to one or several inverters or the
Sunny Multigate. Events can be information, warnings or errors. All events are displayed in the
communication product you are using (e.g. Sunny Portal, Sunny Explorer). Sunny Explorer
additionally displays the corresponding event number for each event.
Inverter
Event Event, cause and corrective measures
number
101 System incident / Grid monitoring spot value (101)
The line voltage or grid impedance at the connection point is too high. The inverter has
disconnected from the utility grid.
Corrective measures:
• Check whether the line voltage at the connection point is permanently in the
permissible range.
If the line voltage is outside the permissible range due to local grid conditions,
contact the grid operator. The grid operator must approve changes to the
operating parameters of the inverter.
If the line voltage is permanently within the permissible range and this message is
still displayed, contact the SMA Service Line.
102 Grid fault / Grid overvoltage fast (102)
The line voltage or grid impedance at the connection point of the inverter is too high.
The inverter has disconnected from the utility grid.
Corrective measures:
• Check whether the line voltage at the connection point of the inverter is
permanently in the permissible range.
If the line voltage is outside the permissible range due to local grid conditions,
contact the grid operator. The grid operator must approve changes to the
operating parameters of the inverter.
If the line voltage is permanently within the permissible range and this message is
still displayed, contact the SMA Service Line.
