Troubleshooting Inverter Faults
If a fault has occurred the inverter will cease power production until the fault is
cleared. A fault may be a latching or non-latching fault.
•
Non-latching: Automatically clears if the fault condition is resolved and the
inverter automatically restarts after completing its startup sequence.
• Latching: Requires manual intervention to restart the inverter.
If the inverter has faulted, the display screen will show the corresponding fault
information in a series of three or more screens. The display will then cycle back
through the three screens.
• First screen: Displays the fault category followed by the hexidecimal fault
code(s) value.
• Second screen: Displays a text description of the fault code(s).
• Third screen: Displays Solar Energy Technical Support contact information.
In the following example, a system fault, SYS returned a code, indicating too many
fault restarts occurred. The 0000 indicates no fault occurred in the other fault
groups.
