Check that ground cables are securely
connected.
The rst inspection is
6 months after the
initial
commissioning.
From then on, the
interval can be 6 to
12 months.
8.3 Troubleshooting
Alarm severities are
dened as follows:
● Major: The SUN2000 enters the shutdown mode or functions abnormally
after a fault occurs.
● Minor: Some components are faulty but the SUN2000 can still connect to the
power grid and generate power.
● Warning: The SUN2000 functions normally, but its output power decreases
due to external factors.

Severity
Possible Causes Troubleshooting
2001 High String
Input Voltage
Major The PV array is not properly
congured. Excessive PV
modules are connected in
series to the PV string, and
therefore the open-circuit
voltage exceeds the
maximum SUN2000
operating voltage.
Cause ID = 1, 2
● 1: The PV1 input voltage
is high.
● 2: The PV2 input voltage
is high.
Check the serial connection
conguration of the PV
string and ensure that the
PV string open-circuit
voltage is not greater than
the maximum operating
voltage of the SUN2000.
After the PV array
conguration is corrected,
the alarm disappears.
2002 DC Arc Fault Major The PV string power cables
arc or are in poor contact.
Cause ID = 1, 2
● 1: PV1 DC arc fault
● 2: PV2 DC arc fault
Check whether the string
cables arc or are in poor
contact.
