• While the system checks for grid connection to be established ("Missing Grid"), the yellow
LED next to the display turns on continuously, while the green LED is flashing.
• When waiting for the input voltage to exceed 50Vdc ("Waiting Wind"), the green LED
turns on steady.
• When the "Missing Grid" and "Waiting Sun" conditions are verified, the inverter is
connected.
For -A models only, as soon as Waiting Sun conditions are met, the inverter display shows
the AFD board self-test running. The results are displayed in the two-line graphic display
area.
If a problem on the AFD board is detected, the self-test will result in an error.
Refer to troubleshooting, section 5, to clear the error and possible solutions.
If there are no irregularities after checking the grid voltage and frequency parameters, the grid
connection sequence starts and the inverter displays the following screens:
3) Time (seconds) to complete output voltage and frequency check.
It takes from 30 seconds to several minutes to complete the operation.
Next connections
2 secs
4) Shows instant output voltage value and within/outside range status.
Vgrid 223.8V
In range
5) Shows instant output frequency value and within/outside range status.
Fgrid 60.17Hz
In range
6) If measured instant values of voltage (step 4) and frequency (step 5) are outside of the
allowed range, the following screens are shown alternately
- Next connections (screen 3)
- Vgrid (screen 4)
- Fgrid (screen 5)
Error messages
After the connection is established, the inverter runs a test cycle. If wrong data are found, the
cycle is interrupted and an error code is displayed. Error codes and their meaning are shown
in section 5.
Once the error has been corrected, the inverter resets all functions in progress and re-starts
the connection.
