Name in the manufacturer's documentation (user manual): AFCI Fault[1]

In plain words (editorial)

AFCI (arc fault) – the inverter detected an electric arc on the DC side. The manual says to check the panel terminals after shutdown and restart the inverter.

When to call a service technician: Have an installer check the DC connections; if the message still exists, contact your installer or Growatt.
