Maintenance and Troubleshooting
Event Codes
There are three levels of event codes: Critical event, Warning event, and Information event.
Critical Events
Critical events: the inverter will cease producing AC power and cannot self-recover. This is indicated by the inverter
illuminating both the red Power Fault LED (triangle) and the yellow Maintenance LED (wrench). Note that some of these
Critical events can create a hazardous situation, indicated by DO NOT TOUCH.
DANGER
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
combiners, 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.
