● Warning: The inverter works properly. The output power decreases or some
authorization functions fail due to external factors.
Table 8-2 Common alarms and troubleshooting measures
Alarm
ID
Alarm
Name
Alarm
Severity
Possible Causes Troubleshooting
2001 High
string
input
voltage
Major The PV array is not
properly
congured.
Excessive PV
modules are
connected in series
to the PV string,
and therefore the
PV string open-
circuit voltage
exceeds the
maximum inverter
operating voltage.
● Cause ID 1: PV
strings 1 and 2
● Cause ID 2: PV
strings 3 and 4
Reduce the number of PV modules
connected in series to the PV string until
the PV string open-circuit voltage is less
than or equal to the maximum inverter
operating voltage. After the PV string
conguration is corrected, the alarm
disappears.
2003 DC arc
fault
Major The PV string
power cables arc or
are in poor contact.
Cause ID 1–4: PV
strings 1–4
Check whether the PV string cables arc
or are in poor contact.
2011 String
reverse
connectio
n
Major The PV string
polarity is reversed.
Cause ID 1–4: PV
strings 1–4
Check whether the PV string is reversely
connected to the inverter. If yes, wait
until the solar irradiance declines at
night and the PV string current drops to
below 0.5 A. Then, turn o the DC
switch and correct the PV string
connection.
2012 String
current
backfeed
Warning The number of PV
modules connected
in series to the PV
string is
insucient. As a
result, the terminal
voltage is lower
than that of other
strings.
Cause ID 1–4: PV
strings 1–4
1. Check whether the number of PV
modules connected in series to the
PV string is less than that of other PV
strings. If yes, wait until the PV string
current drops below 0.5 A, turn o all
DC switches, and adjust the number
of PV modules in the PV string.
2. Check whether the open-circuit
voltage of the PV string is abnormal.
3. Check whether the PV string is
shaded.
