No comparison between master and slave
The error and event memory are not compared between the master and slaves. The errors of
the slave device are acknowledged when the Sunny Island system is restarted.

20.4 Handling of Pending Errors during the Booting Procedure

During the booting procedure, all pending failures are generally confirmed without an entry being
made in the history. This way, after the booting procedure, a failure that is still pending will be
reentered, or if the system detects that this failure has disappeared, it is entered as no longer being
present.

20.5 Display of Failures and Events

Each failure and each event have a unique three-digit display number that is created according to the
parameter/measuring value assignment. The events and failures have the identical numerical range:
• 1xx ‒ INV ‒ Inverter
• 2xx ‒ BAT ‒ Battery
• 3xx ‒ EXT ‒ External
• 4xx ‒ GEN ‒ Generator
• 5xx ‒ GRD ‒ Grid
• 6xx ‒ RLY ‒ Relay
• 7xx ‒ SYS ‒ System
• 8xx ‒ AUX ‒ External devices and components
Meaning of abbreviations
"F" indicates a failure, "W" a warning and "E" an event.
In the event of a failure, and provided it is recorded, "!" is displayed for a failure that has
occurred and "C" is displayed for a failure that has stopped.
