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.
