What you will see
- One microinverter shows red
- One or two panels missing in the app
- Flashing red after an update was started
Why it happens
Each microinverter checks grid, panel voltage and temperature on its own, so one can stop while the others run. Flashing red during an update is normal; leave it to finish in good light.
