● Warning: The inverter works properly. The output power decreases or some
authorization functions fail due to external factors.
Table 8-1 Common alarms and troubleshooting measures
Alarm
ID
Alarm Name Alarm
Severity
Cause Troubleshooting Suggestions
2001 High String
Input Voltage
Major The PV array is not
properly congured.
Excessive PV modules are
connected in series to a
PV string, and therefore
the PV string open-circuit
voltage exceeds the
maximum operating
voltage of the inverter.
● Cause ID 1: PV strings
1 and 2.
● Cause ID 2: PV strings
3 and 4.
● Cause ID 3: PV strings
5 and 6.
● Cause ID 4: PV strings
7 and 8.
● Cause ID 5: PV strings
9 and 10.
● Cause ID 6: PV strings
11 and 12.
● Cause ID 7: PV strings
13 and 14.
● Cause ID 8: PV strings
15 and 16.
● Cause ID 9: PV strings
17 and 18.
Reduce the number of PV
modules connected in series in
the PV string until the PV
string open-circuit voltage is
not greater than the maximum
operating voltage of the
inverter. After the PV array
conguration is corrected, the
alarm disappears.
2011 String Reverse
Connection
Major The PV string is reversely
connected.
Cause ID 1–18: PV strings
1–18
Check whether the PV string is
reversely connected to the
inverter. If yes, wait until the
PV string current drops below
0.5 A. Then, set all DC switches
to OFF and correct the PV
string connection.
