Troubleshooting Inverter Faults

If
a fault has occun-ed, the inve1ter 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 restaits after completing its staitup 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 O O O O indicates no fault occurred in the other fault
groups.
