9.2.1 Inverter fault
Input current out of
tolerable range or inverter’s
component is damaged.
1.Check input current is within
the tolerable range.
2.If error message still exists
despite the checking was passed,
contact Growatt.
Communication board has
not received data from
control board for 10
seconds. Electromagnetic
Interference cause
communication problem.
1.Reboot inverter by cutting off
DC supply, and Error message
will disappear.
2.If the error 101 is often displayed,
the environment Electromagnetic
Interference is too strong.
Contact Growatt.
Model setting fault. Reason
can be Model and safety
requirement have not been
set correctly.
Contact Growatt..
Inverter’s component is
damaged.
Contact Growatt.

Meanings
Suggestion
For 18K/20K inverter:
Problem with fan No.4.
For 8K/10K inverter:
Problem with No. 2 fan.
Note: If there is problem
with other fans, inverter
continue running with
warning on LCD showing:
Fan Error.
1.Replace faulty fan.
2.If problem still exists after
replacement, contact Growatt.

Suggestion
Error: 122
Bus voltage out of range. 1.Check if input voltage is within
the voltage range.
2.If input voltage is around 1000V,
reboot the inverter with lower
input voltage.
3.If error message still exists,
contact Growatt.
Error: 120
