Event number Message, cause and corrective measures
1612 Grid disconnection release as power limit not reached
Relevant for load-dependent grid requirement: The power requirement of the loads has fallen
below the power limit stored in the battery inverter. The battery inverter issues the release for
grid disconnection.
1613
Manual grid request
1614
Manual grid disconnection release
1615
Locking of generator due to excessive connect. processes
Blocking of generator due to too many interrupted start-ups
Corrective measures:
A warm-up time Warm-up time of generator that is too short may have been configured
and hence the generator is unable to supply valid voltage.
1616
Synchronization not executed
Synchronization with the generator not successful.
1701
Automatic frequency control intervenes
1702
Automatic frequency control ends
1704
Generator operation not possible
Generator operation not possible
Corrective measures:
1705 No valid grid voltage for requested grid operation
Voltage of the external energy source is not within the valid thresholds for connection.
Corrective measures:
146 SI44M-80H-13-BE-en-15
• Ensure that the generator triggering is functioning, the generator starts, and there is
constant and stable generator voltage present at connection AC2.
• Ensure that the warm-up time for the generator is set to a sufficient duration.
• To re-enable connection of the generator, acknowledge the error.
• Ensure that the generator can be started. The fuel level may be too low.
• Ensure that a constant and stable voltage is present at connection AC2.
• Ensure that the thresholds for the generator voltage are correctly configured.
• Reset the off-grid system. For this, disconnect all loads, AC sources, generator and DC
sources. Open the battery fuse load-break switch. Wait 10 minutes and restart the off-
grid system. Wait until all AC sources are feeding into the stand-alone grid and all loads
are connected before connecting the generator.
• Contact the Service.
• Acknowledge the error.
• Contact the Service.
