Most inverters expose fault information that can be detected by WattMetrics. WattMetrics logs inverter faults and lists them under the "fault history" tab on the inverter detail page in the projects portal.
Acknowledging Inverter Fault Messages
Inverter faults can only be acknowledged via the "fault history" tab on the inverter detail page. This ensures that only users with access to the project through the project portal (presumably the installer) can 'clear' the fault.
Inverter Faults and Alert Status
The inverter fault alert will remain triggered until all faults have been acknowledged.
