21.4 Display of Errors and Events
Every error and event is uniquely marked and created according to the parameter/measuring value
assignment.
The message has four digits and consists of one letter and three numbers.
1. Depending on the message, it begins with a letter. There are three categories of messages:
– F = Error/Failure
– W = Warning
– E = Event
2. The second position is a number between 1 and 8 that describes the area in which the error,
event or warning occurred:
– y1xx - INV = Inverter
– y2xx - BAT = Battery
– y3xx - EXT = External
– y5xx - GRD = Grid
– y6xx - RLY = Relay
– y7xx - SYS = System
– y8xx - BOX = Automatic Switch Box S
3. The third and
4. fourth positions contain two digits. These numbers provide information on the frequency in which
this particular message has occurred.
In addition, the Sunny Remote Control 1 indicates whether the message is still current, i.e. if an action
is required or the message has been settled.
• „!“ for set – the Sunny Backup 2200 has detected an error (again) and enters it in the list.
• "C" for clear – the cause of the error has been successfully corrected; the error is "no longer
present".
