7 TROUBLESHOOTING
The PV Inverter is supplied with a self-diagnosis system that identifies automatically a large number of
anomalies and displays these on the LCD screen. It is therefore possible to isolate technical problems
very quickly and to differentiate between the Service Codes relating to the installation from those internal
anomalies of the PV Inverter. Whenever the self-diagnosis system identifies a specific problem, the
corresponding Service Code is displayed on the LCD screen.
Table 1. The error code of the PV Inverter and a description of the error code
Information  error appears in Events
Warning  the second led lights, yellow led, and error appears in Events
Alarm  the third led lights (red led) and error appears in Events. Though this error is solved it is
necessary reset the failure from the display: “Orders”
The inverter
indicates
Error Number Designation Description Remedy
Warning 1 High Vp
The photovoltaic voltage
(DC) above the maximum
limits of the inverter.
1. Disconnect ALL the PV (+) or
PV (-)
2. Wait for a few seconds.
3. After the LCD turns off,
reconnect and check again.
4. If the same error occurs again,
contact with the local distributor.
Warning 2 Ve min
The photovoltaic voltage
(DC) below the minimum
limits of the inverter.
Wait for generating more energy.
If the error doesn’t stop, contact
with the local distributor.
Warning 3 Low Rais
Insulation resistance under
500K
Ω
1. Disconnect ALL the PV (+) or
PV (-)
2. Wait for a few seconds.
3. After the LCD turns off,
reconnect and check again.
4. If the same error occurs again,
contact with the local distributor.
Alarm 4 COM failure
Communications failure
between DSP and the
inverter
Warning 5 Island
The inverter detects that
there is no reference grid
voltage.
Disconnect the AC circuit breaker.
Then check the configuration of
the peripheral AC system and the
grid conditions. If the failure
reoccurs, ask the local distributor
for help.
Alarm 6 Inv failure
The Inverter has not
operated or does not operate
correctly.
Seek the help to the local
distributor.
Alarm 7 Vbus Min
The internal DC BUS is
lower than expected Seek the help to the local
distributor.
Alarm 8 Vbus Max
The internal DC BUS is
higher than expected Seek the help to the local
distributor.
Warning 9 PLL fail Vgrid synchronization fail
Seek the help to the local
distributor.
Alarm 10 Overtemperature
The internal temperature of
the inverter is too high.
1. Try reducing the atmospheric
temperature.
2. Move the PV Inverter to a
cooler place.
3. If the error code reappears,
seek the help to the local
distributor.
Alarm 11 Precharge failure
Bus capacitor’s precharge
failure
Seek the help to the local
distributor.
