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.
ID14 HwBoostOCP
The input current
is too high , and
has happen
hardware
protection
Check whether the input current is higher
than the maximum input current of
inverters, then check the input wiring, if
both are correct, please contact technical
support.

ID15-ID24 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.

If the PV array configuration is correct (no
ID05 fault), the possible cause is that the
solar irradiance is too low. inverter
