7. TROUBLE SHOOTING
In most situations, the Inverter requires very little service. However, if Inverter is
not able to work perfectly, please refer to the following 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?
No any display in LCD or LED
Check PV-input connections
W01 No grid
Check grid connection cables.
W02 Vin overvoltage
Check the Voc of PV string, see if it is greate
r
than or too close to max. input DC voltage o
f
relative inverter type.
E01 Isolation error
Check the impedance is between PV (+) & P
V
(-) and the PV-Inverter is earthed. Th
e
impedance must be greater than 2MΩ
E02 Ileak error
The leakage current is too high. Unplug th
e
inputs from the PV string and check th
e
peripheral AC system.
E03 Grid fault
Make sure grid voltage and frequency meet th
e
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, not a trouble.
If you can not solve the trouble with above procedures, Please
contact your local dealer or service personnel.
Before contacting the authorized local dealer or service personnel, please find and
keep at hand the following information:
