Description
Even Reason & 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.
ID02
GridUVP
The power grid
voltage is too low
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.
ID03
GridOFP
The power grid
frequency is too
high
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,
over frequency, under-frequency
protection points after obtaining
approval from the local electrical
grid operator.
ID04
GridUFP
The power grid
frequency is too
low
ID05
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 long time,
check whether the insulation
resistance between the PV array
and earth(ground) is too low, then
check the insulation conditions of
