Sunny Island Inverter Behavior Under Fault Conditions
Error Levels
The Sunny Island distinguishes between five different levels of errors, each requiring different user interaction.

Explanation
1
Warning
Warning
Warning; the Sunny Island continues to run. Information in standard
mode indicating that a warning has been generated.
2
Malfunction 1 Malfunction
Malfunction that is detectable only during operation. The Sunny Island
shuts down. Restart can be initiated immediately (e.g. via autostart).
3
Malfunction 2 Malfunction
Malfunction that is also detectable in standby mode. The Sunny Island
shuts down. Restart is blocked until the malfunction is no longer de-
tected by the Sunny Island.
4
Failure
Failure
Device failure; the Sunny Island switches off. Troubleshooting, acknowl-
edgment of the error and manual restart necessary.
5
Device defect
Defect
The Sunny Island is defective and switches itself off. The Sunny Island
must be replaced.
Handling of Pending Errors upon Activation
During the activation procedure, all pending errors are acknowledged without the error being logged in the list
420#
Error history
. Errors that are still pending are entered again after activation. Errors that were detected by the
Sunny Island before activation and are no longer detected after activation are shown in the list
420# Error history
.
Autostart
The autostart function allows automatic restarts in the event of malfunctions. If the autostart function fails in the event of
a malfunction, the Sunny Island attempts to carry out the next autostart immediately. The number of autostarts is
restricted. If the Sunny Island is in operation without malfunctions for ten minutes, it resets the autostart counter.
When the maximum number of autostarts has been reached, the Sunny Island reacts as follows:
• The Sunny Island waits ten minutes.
• The autostart counter is reset.
• The Sunny Island attempts to perform an autostart.
• When the maximum number of autostarts has been reached, the Sunny Island waits again for ten minutes.
10.3
Acknowledge Errors
If a malfunction or failure occurs, the Sunny Island switches to standby mode. Once you have eliminated the cause of
the error, you can enable a restart of the Sunny Island inverter by acknowledging the error.
Procedure:
1. Eliminate the cause.
2. Press the button on the Sunny Remote Control. This acknowledges the error.
3. Start the system (see Section 4.2, page 20).
