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
HwAcOCP
The grid current is
too high , and has
happen hardware
protection
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.

ID24
IacRmsUnbalance
The Output current
is not balanced
ID25
BusUVP
The bus voltage Is
too low
If the PV array configuration is correct (no
ID05 fault), the possible cause is that the solar
irradiance is too low. inverter automatically
returns to normal operating status after the solar
irradiance returns to normal level.
ID26
BusOVP
The bus voltage Is
too high
ID26-ID27 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.
ID27
VbusUnbalan
The bus voltage is
not balanced
ID28
DciOCP
The Dci is too high
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.
If the input mode is correct, 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,
