9 Alarm Reference
Alarm severities are dened as follows:
● Major: The inverter is faulty or the external environment is abnormal. As a
result, the output power decreases or the inverter stops feeding power into
the grid.
● Minor alarm: Some components of the inverter are faulty but the inverter can
still connect to the grid and generate power.
● Warning: The inverter works properly. The output power decreases or some
authorization functions fail due to external factors.
