Event number Message, cause and corrective measures
1402
Grid incident
The voltage of the generator or the utility grid at the Sunny Island at line conductor Lxx is out-
side the configured thresholds (redundant measurement).
Corrective measures for generator:
Corrective measures for utility grid:
1403
Grid incident
The Sunny Island at line disconnector Lxx disconnects from the external energy source be-
cause the ratio of AC voltage and battery voltage is too high. Either the voltage at connec-
tion AC2 is too high or the battery voltage too low.
Corrective measures:
1404
Grid incident
The Sunny Island at line conductor Lxx disconnects from the utility grid due to phase conduc-
tor failure/overload at terminal AC2.
Corrective measures:
1405
Grid incident
A short circuit is present at connection AC2 of the Sunny Island at line conductor Lxx.
Corrective measures:
1407
Grid incident
Disconnection from the utility grid due to non-compliance with the voltage-frequency ratio at
line conductor Lxx
Corrective measures:
Operating manual
• Change the voltage thresholds for the generator. As an aid to this, observe and
evaluate the measured values Voltage of external grid connection Lxx during
ongoing operation.
• If possible, adjust the generator voltage.
• Contact the Service.
• Contact the Service.
• Reduce the total power of the loads, e.g. by staggering their use over time.
• Ensure that there is not a short circuit present at connection AC2.
• Contact the Service.
• Contact the Service.
