15. ERROR CODES
The Inverter can detect faults during operation. The inverter will display the fault in the GUI. Faults are
indicated in the GUI with an error code, and a plain text message with the error code and system plant name
in the text line will be sent to the system operator (only available if purchased and configured during setup).
This section describes how to recognize the types of faults and how to correct these faults.
