9.2.2 Error
The error code indicates that the device is damaged or the configurations are
abnormal. Only qualified and trained electrical technicians are allowed to rectify
the faults. The error message will disappear after the fault is rectified. If the
problem persists, please contact Growatt.
Error Code
Description
Suggestion
AFCI Fault
An arc fault has
been detected
2. Restart the inverter.
1. After shutdown, check the
connection of the PV string.
3. If the error message persists, please
contact Growatt support.
GFCI High
An excessively high
leakage current has
been detected
1. Restart the inverter.
2. If the error message persists, please
contact Growatt support.
PV Voltage High
DC input voltage
exceeds the upper
threshold
1. Disconnect the DC switch
immediately and check the voltage.
2. If the DC input voltage is within the
permissible range and the error
message persists, please contact
Growatt support.
PV Isolation Low
PV panels have low
insulation
resistance
2. If the error message persists, please
contact Growatt support.
1. Check if the PV strings are properly
grounded.
PV Reversed
PV string reversely
connected
1. After shutdown, check if the PV string
is reversely connected to the inverter.
3. If the error message persists, please
contact Growatt support.
2. Restart the inverter.
AC V Outrange
Grid voltage is
beyond the
permissible range
1. Check the grid voltage.
2. If the grid voltage is within the
permissible range and the error
message persists, please contact
Growatt support.
No AC
No utility grid
connected or utility
grid power failure
1. After shutdown, check the AC wiring.
2. If the error message persists, please
contact Growatt support.

Error Code
Description
Suggestion
NE Abnormal
The voltage
difference between
the N line and the PE
cable is abnormal
2. If the error message persists, please
contact Growatt support.
1. After shutdown, check if the ground
cable is reliably connected.
AC F Outrange
Grid frequency is
beyond the
permissible range
2. If the error message persists, please
contact Growatt support.
1. Check the grid frequency and restart
the inverter.
Error 309
Grid ROCOF (Rated
of Change of
Frequency)
abnormal
2. If the error message persists, please
contact Growatt support.
1. Check the grid frequency and restart
the inverter.
NE Fault
Neutral-to-Ground
voltage is too low
2. If the error message persists, please
contact Growatt support.
1. Check whether the N line on the
inverter side with PV negative
grounding is short-circuited with the
ground cable and whether the output
side is isolated with a transformer.
Error 311
Export limitation
fail-safe
1. After shutdown, check the
connection of the CT and the meter.
2. If the error message persists, please
contact Growatt support.
Error 400
DCI bias abnormal
1. Restart the inverter.
2. If the error message persists, contact
Growatt support.
Error 402
High DC component
in output current
1. Restart the inverter.
2. If the error message persists, contact
Growatt support.
Error 404
Bus voltage
sampling abnormal
1. Restart the inverter.
2. If the error message persists, please
contact Growatt support.
Error 405
