Event number Message, cause and corrective measures
1412
Grid fault
The pre-fuse F104.1, F104.2 or F104.3 in the Multicluster-Box is open. A Sunny Island in
the main cluster (master / slave 1 / slave 2) detects a supply voltage at ExtVtg and tries to
switch to L1 / L2 / L3 in the multicluster system. Because L1 / L2 / L3 is missing due to the
open pre-fuse, this results in an anti-islanding error.
Corrective measures:
1413
Grid fault
Phase position of the measured AC voltage at ExtVtg and AC2 does not match at line con-
ductor L1 / L2 / L3.
Corrective measures:
1415
Grid fault
Tie switch does not close.
Corrective measures:
1416
Grid fault
The Sunny Island system disconnects from the generator or utility grid due to a voltage imbal-
ance between the line conductors.
Corrective measures:
1601
Automatic generator start due to set criteria, e.g. battery state of charge
1602
Automatic generator stop due to set criteria, e.g. battery state of charge
1603
Manual generator start
1604 Manual generator stop
1605 Manual error acknowledgment of generator error
Operating Manual
• Reactivate the pre-fuse.
• Check the voltage supply at terminal AC2 of the master in the main cluster.
• Ensure that the neutral conductor and line conductor are correctly connected to
connection ExtVtg.
• Ensure that the neutral conductor and line conductor are correctly connected to
connection AC2.
• Ensure that connections ExtVtg and AC2 are connected to the same line conductor.
• Ensure that the triggering of the tie switch is correct.
• Ensure that the tie switch is correctly wired.
• Ensure that the feedback contact is correctly connected.
• Eliminate any faults in the installation.
