Fault

1.  Disconnect all PV (+) or PV (-) from solar panels

2.  Wait for a few seconds.

3.  After the LCD switches off, reconnect and check again.

4.  If the problem remains, please call local service.

For products which are out of warranty, factory charges an on-site service fee, parts, labor cost and logistic fee to end-user 
which can be any/all of:

     On-site attendance fee: Cost of travel and time for the technician in attending on-site;
     Parts: Cost of replacement parts (including any shipping/admin fee that may apply);
     Labor: Labor time fee charged for the technician, who is repairing, maintaining, and installing (hardware or software) and 
     debugging the faulty product;
     Logistic fee: Cost of delivery, tariff and other derived expense when defective products are sent from user to factory or / 
     and repaired products are sent from factory to user;

Possible actions

Isolation Fault

Isolation Fault 2

LCD display

Clearable Fault

Fault

1.  Check whether the inverter is earthed and test impedance between PV (+) 

& (-) and the impedance must exceed 3MΩ;

2.  Check whether the AC-side has contacts with earth.

Grid Faults:

Fault OVR
Fault UVR
Fault OFR
Fault UFR

1.  Wait for 5 minutes, if the grid returns to normal, PV inverter automatically 

restarts.

2.  Make sure grid voltage and frequency meet the local specifications.

No Utility

1.  Grid is not connected.

2.  Check grid connection cables.

3.  Check grid usability.

4.  If grid is ok and the problem exists still, maybe the fuse in the inverter is 

open, please call service.

OverTemp

1.  The internal temperature of inverter is higher than specified normal value.

2.  Find a way to reduce the ambient temperature.Or move the inverter to a

 cooler environment.

PVOVFault

PV2OVFault

1.  Check the open PV DC voltage, and see if it is greater than or too close to 

950VDC

2.  If PV DC voltage is less than 950VDC, and the problem still occurs, please 

call local service.

Appendix A: FAQ (Frequently asked questions)

Sometimes, the PV system does not work normally; we recommend the following solutions for average troubleshooting. 
This can help the technician to understand the problem and take a proper action.
