and then turn on the switch again;
4.Contact after-sales service personnel
Definition:
PV module is connected inversely
Possible causes:
PV positive pole and negative pole are connected
inversely;
Recommended solutions:
1.Check whether positive pole and negative pole
are connected inversely;
2.Contact after-sales service personnel
Definition:
System leakage current is too high
Possible causes:
1.Excessive parasitic capacitance on PV module
due to environmental factor;
2.Grounding is abnormal;
3. Internal inverter fault
Recommended solutions:
1.Observe for 5 minutes and see whether the alarm
will be eliminated automatically;
2.Detect whether the electrical connection is
abnormal
3.Contact after-sales service personnel
Definition:
Insulation impedance of PV positive to ground or
PV negative to ground exceeds the specified range
