Type Description
Error type 1 (Warning) The Sunny Central does not switch off. Once the error is no longer
present, the error signal is reset automatically. Check the system.
Error type 2 (Fault) The Sunny Central switches off. Once the error is no longer
present, the error signal is reset automatically, and the Sunny
Central starts up again.
Error type 3 (Fault) The Sunny Central switches off. Error type 3 can only arise if the
Sunny Central is in grid feed operation when an error occurs.
Once the error is no longer present, the error signal is reset
automatically, and the Sunny Central starts up again.
Error type 4 (Fault) Error type 4 must be cleared before the Sunny Central can resume
operation.
The Sunny Central switches off. Rectify the cause of the error, and
clear the error at Sunny Central Control, or with Sunny Data
Control. Once you have cleared the error, the Sunny Central
resumes operation.
