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
● 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 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 are combined
or exchanged.
● Cause ID 8: The sunlight
is weak or changes
abnormally.
● Cause ID 9: In partial
configuration scenarios,
the PV string voltage
exceeds the SUN2000
input voltage
specifications.

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).
