Under sunMAX Monitoring software, Microinverters may appear offline for a number of different reasons. In general, it will appear offline whenever there is insufficient power on the DC or AC side of the Microinverter. This is important from the perspective of efficiency as well as safety, including:
- Night-time hours (no DC power because no sunlight)
- Grid service stops (no AC power due to grid maintenance).
Inspect the AC Module if the Microinverter remains offline during normal hours with active Grid Service.
Inspect the Gateway and End-Run if the entire array or select branches go offline during normal hours.
