● 2: The PV string power
or the number of
optimizers connected in
series in a PV string
exceeds the upper
threshold.
● 3: The number of
optimizers connected in
series in a PV string is
less than the lower
threshold, the PV string
output is reversely
connected, or the output
of some optimizers in
the PV string is reversely
connected.
● 6: Under the same
MPPT, the number of
optimizers connected in
series in PV strings
connected in parallel is
different, or the output
of some optimizers in
PV strings is reversely
connected.
● 7: The optimizer
installation position is
changed, or PV strings
are combined or
exchanged.
● 8: The sunlight is weak
or changes abnormally.
● 9: In partial
configuration scenarios,

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.
