WARNING: This product can cause current with a d.c. current component.
Where a residual current-operated protective device (RCD) or monitoring
device(RCM) is used for protection in case of direct or indirect contact, only an
RCD or RDM of Type B is allowed on the supply side of this product.
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.
No any display in LCD or LED
Check PV-input connections
Check grid connection cables.
Check the Voc of PV string, see if it is greater
than or too close to max. input DC voltage of
relative inverter type.
Check the impedance is between PV (+) & PV
(-) and the PV-Inverter is earthed. The
impedance must be greater than 2MΩ
The leakage current is too high. Unplug the
inputs from the PV string and check the
peripheral AC system.
Make sure grid voltage and 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, 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:
