Maintenance and Troubleshooting

If an inverter is not running correctly, the Status Panel will show that there is an issue. When the inverter is
working normally, the three leftmost LEDs are lit (Ready, Network and Communications, and Power) and the
two on the right will be off (Maintenance and Power Fault). If the Maintenance LED or the Maintenance and
Power Fault LEDs are illuminated, the inverter requires attention. (Refer to Section 1.4)
The User Interface will also show when an inverter is not running correctly. When the inverter is
working correctly, the inverter list will show a green checkmark next to the inverter.

Event Codes

There are three levels of event codes: critical event, warning event, and information event.
7.1.1
Critical Events
Critical events will always cause the inverter to cease producing AC power and the
inverter cannot self-recover. This is indicated by the display illuminating both the red
Power Fault LED (triangle) and the Yellow Maintenance LED (wrench). Note that some of
these events can create a hazardous situation, indicated by DO NOT TOUCH in Table 7-1
Critical Event Codes.
Ground Fault Hazard
Inverter enclosure is an electrical hazard.
DO NOT TOUCH any equipment (including, but not limited to: the inverter, the PV array
disconnect switch, the PV array combiner, the PV panels, or the PV racking system).
Immediately contact the installer or another qualified person to locate and repair the
source of the ground fault.
