Alarm Possible Cause
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 Suggestion
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.
● ID9: Calculate the PV string
voltage based on the number of
PV modules in the PV string and
check whether the PV string
