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 PV cable.
ID06
OVRT
OVRT faulty
There are internal faults of inverter, turn OFF the
“DC switch”, wait for 5 minutes, then turn ON the
“DC switch”. Check whether the fault is rectified.
If no, please contact technical support.
