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,
over frequency, under-frequency
protection points after obtaining
approval from the local electrical
grid operator.

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
PV cable.
