Major ● Cause ID = 1
The number of
optimizers connected to
the inverter exceeds the
upper threshold.
● Cause ID = 2
The PV string power or
the number of
optimizers connected in
series in a PV string
exceeds the upper
threshold.
● Cause ID = 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.
● Cause ID = 4
The number of PV
strings connected to the
inverter exceeds the
upper threshold.
● Cause ID = 5
The PV string output is
reversely connected or
the PV string output is
short-circuited.
● Cause ID = 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.
● Cause ID = 7
The optimizer
installation position is
changed, or PV strings
Check whether the total number
of PV modules, number of PV
modules in a PV string, and
number of PV strings meet
requirements and whether the
PV module output is reversely
connected.
● Cause ID 1: Check whether
the total number of
optimizers exceeds the upper
threshold.
● Cause ID 2: Check whether
the PV string power or the
number of PV strings
connected in series exceeds
the upper threshold.
● Cause ID 3:
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).
● Cause ID 4: Check whether
the number of PV strings
exceeds the upper threshold.
● Cause ID 5: Check whether
the PV string output is
reversely connected or short-
circuited.
● Cause ID 6:
1. Check whether the
number of optimizers
connected in series in the
PV strings connected in
