Class 3 status Class 3 includes status codes that may occur while feeding energy into the grid, but gen-
codes erally do not cause the process to be interrupted for any length of time.
The inverter disconnects automatically from the grid, the grid is then monitored as specified
and the inverter attempts to resume feeding energy into the grid.
Code Description
301 Overcurrent (AC)
Power stage set overtempera-
303
ture
304 Internal temperature too high
If the grid relay is closed, no
305
energy is transferred to the grid
DC low
307 DC input voltage too low for
feeding energy into the grid
IMPORTANT! Due to the low level of insolation early in the morning and in the evening, the status code 307 (DC
low) is routinely displayed at these times of day. This status code does not indicate any kind of fault.
309 DC input voltage too high
321 Overcurrent (AC)
Overtemperature on the air in-

Behaviour
Short-term interruption while
feeding energy into the grid
due to overcurrent in the invert-
er
The inverter resumes with its
start-up routine.
