Alarm Possible Causes
Severity
Major PV module configuration
does not meet
requirements, or the PV
module output is reversely
connected or short-
circuited.
Cause ID = 2, 3, 6, 7, 8, 9
● 2: The PV string power
or the number of PV
modules connected in
series exceeds the upper
threshold.
● 3: The PV string voltage
is low or the number of
PV modules connected
in series is less than the
lower threshold.
● 6: The PV string or
parallel connection is
abnormal.
● 7: The string
configuration is
changed.
● 8: The sunlight is
abnormal.
● 9: The PV string voltage
exceeds the upper
threshold.

Troubleshooting
Check whether the total number
of PV modules, number of PV
modules in a string, and number
of PV strings meet requirements
and whether the PV module
output is reversely connected.
● ID2: Check whether the PV
string power or the number
of PV modules connected in
series in the PV string exceeds
the upper threshold.
● ID3:
1. Check whether the number
of optimizers connected in
series in the PV string is
below the lower threshold.
2. Check whether the PV
string output is reversely
connected.
3. Check whether the PV
string output is disconnected.
4. Check whether the
optimizer output extension
cable is correct (positive
connector at one end and
negative connector at the
other).
● ID6:
1. Check whether the number
of optimizers connected in
series in the PV strings
connected in parallel under
the same MPPT is the same.
2. Check whether the
optimizer output extension
cable is correct (positive
connector at one end and
negative connector at the
other).
● ID7: When the sunlight is
normal, perform the
optimizer search function
again.
● ID8: When the sunlight is
normal, perform the
optimizer search function
again.
