3.GridF.OutLim
Definition:
Grid voltage frequency is abnormal, or power grid
is not detected
Possible causes:
1.Grid frequency is abnormal;
2.Cable connection between the PCS and the grid
is poor;
Recommended solutions:
1.Observe for 10 minutes and see whether the
alarm will be eliminated automatically;
2.Check whether the grid frequency is within the
specified range;
3.Check whether the cable between the PCS and
power grid is disconnected or has any fault;
4.Contact service personnel
4. Battery VoltOver*
Definition:
Battery voltage exceeds the specified value
Possible causes:
Battery overvoltage
Recommended solutions:
1.Observe for 30 minutes and see whether the
alarm will be eliminated automatically;
2.Check whether Battery voltage exceeds the
specified range;
3.Turn off the Battery input switch, wait for 5
minutes, and then turn on the switch again;
4.Contact service personnel
6.GFCI.Err
Definition:
System leakage current is too high
Possible causes:
1.Excessive parasitic capacitance on Battery
module due to environmental factor;
2.Grounding is abnormal;
3.Internal PCS fault
