GridFault
Grid fault
If the error occurs occasionally, the
probable cause is that the grid has
temporary faults.
If the fault occurs frequently, check
whether the mains voltage and
frequency are in an acceptable range.
If not, contact technical support.
Otherwise, check the conditions of the
AC switch and the cable harness.
ID14
HwBoostOCP
The input current is
too high and has
caused the hardware
protection to be
activated.
Check whether the input current is
higher than the maximum input
current of the inverters, then check
the input wiring; if both are correct,
contact Technical Support.
ID15
HwAcOCP
The grid current is
too high and has
caused the hardware
protection to be
activated.
ID15-ID24 are internal faults of the
inverter; turn off the “DC switch”, wait
5 minutes and then turn it back on
again. Check that the fault is no longer
present. If this is not the case, contact
Technical Support
ID16
AcRmsOCP
The grid current is
too high.
ID17
HwADFaultIGrid
Sampling error of the
grid current.
ID18
HwADFaultDCI
DCI sampling error.
ID19
HwADFaultVGrid
Sampling error of the
grid voltage.
ID20
GFCIDeviceFault
GFCI sampling error.
ID21
MChip_Fault
Master chip fault
ID22
HwAuxPowerFault
Auxiliary voltage
error
ID23
BusVoltZeroFault
Current sampling
error.
ID24
IacRmsUnbalance
The output current is
not balanced.
ID25
BusUVP
The bus voltage is too
low.
If the configuration of the PV string is
correct (no ID05 fault present), the
possible cause is that the solar
radiation is too low. The inverter
automatically returns to its normal
operating state when the solar
radiation returns to a normal level.
