7. TROUBLESHOOTING
In most circumstances, the inverter requires very little servicing. However, if the inverter is not
able to operate in accordance to its function, please refer to the following troubleshooting
instructions before calling your local dealer or service personnel.
If any problems arise, the “Alarm” LED on the front panel will be red and the LCD displays the
relevant information. Please refer to the following table for a list of potential problems and
their solution.
DISPLAY
HOW TO DO?
1 No display in LCD or LED
Check PV-input connections
2 No Utility
Check grid connection cables.
3 PV
over-voltage
Check the Voc of the PV string and see if it is
greater than or too close to the max. input DC
voltage of respective inverter type.
4 Isolation
Fault
Check the impedence between PV (+) & PV (-)
and that the PV-Inverter is earthed. The
impedance must be greater than 2M
Ω
.
5 GFCI
Fault
The leakage current is too high.Unplug the inputs
from the PV string and check the peripheral AC
system.
6 Grid Volt. Fault
Make sure grid voltage meet the specifications
7 Grid Freq. Fault
Make sure grid frequency meet the specifications
NOTE:
During periods of little or no sunlight, the solar inverter may continuously start up and
shut down. This is due to insufficient power generated to operate the control circuits.
If you are not able to resolve the issues through the above troubleshooting procedures,
please contact your local dealer or service personnel.
Before contacting the
authorized local dealer or service personnel, please have the following information:
