Solution
ID01 GridOVP
The power grid
voltage is too high If the alarm occurs occasionally, the
possible cause is that the electric grid is
abnormal occasionally. inverter automatically
returns to normal operating status when the
electric grid’s back to normal.
If the alarm occurs frequently, check
whether the grid voltage/frequency is within the
acceptable range. If no, contact technical
support. If yes, check the AC circuit breaker and
AC wiring of the inverter.
If the grid voltage/frequency is within the
acceptable range and AC wiring is correct, while
the alarm occurs repeatedly, contact technical
support to change the grid over-voltage,
under-voltage, overfrequency, under-frequency
protection points after obtaining approval from
the local electrical grid operator.
ID02 GridUVP
The power grid
voltage is too low
ID03 GridOFP
The power grid
frequency is too
high
ID04 GridUFP
The power grid
frequency is too
low
ID05 PVUVP
The input voltage
is too low
Check whether too few PV modules are
series connected in a PV string, thus the
voltage(Vmp) of the PV string is lower than the
minimum operating voltage of inverter. If yes,
adjust the number of series connected PV
modules to increase the voltage of the PV string
to fit the input voltage range of inverter. inverter
automatically returns to normal operating status
after correct adjustments.
ID09 PVOVP
The input voltage
is too high
Check whether too many PV modules are
series connected in a PV string, thus the
voltage(Voc) of the PV string is higher than the
maximum input voltage of inverter. If yes, adjust
the number of series connected PV modules to
decrease the voltage of the PV string to fit the
input voltage range of inverter. inverter
automatically returns to normal operating status
after correct adjustments.
ID10 IpvUnbalance
Input current is not
balanced Check the input mode(parallel mode/
independent mode) setting of inverter according
to Section 6.3 (C) 6.Input Mode of this user
manual, If it’s incorrect, change it according to
Section 6.3 (A) 10.Set Input mode of this
manual.

ID12 GFCIFault GFCI Fault
If the fault occurs occasionally, the possible
cause is that the external circuits are abnormal
occasionally. inverter automatically returns to
normal operating status after the fault is
rectified.If the fault occurs frequently and lasts a
