4.PV1(2)VoltOver*
Definition:
PV voltage exceeds the specified value
Possible causes:
PV over-voltage
Recommended solutions:
1. Observe for 30 minutes and see whether the
alarm will be eliminated automatically;
2. Check whether PV voltage exceeds the
specified range;
3. Turn off the PV input switch, wait for 5
minutes, and then turn on the switch again;
4. Contact after-sales service personnel
5.PV1(2) Reverse*
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
6. GFCI.Err
Definition:
