ID10
IpvUnbalance
The input current is
not balanced.
Check the configuration of the input
mode (parallel mode / independent
mode) of the inverter, as indicated in
relative section (C) “6. Input Mode” of
this user manual; if it is incorrect,
change it according to relative section
(A).
ID11
PvConfigSetWrong
Incorrect input mode
ID12
GFCIFault
Faulty automatic
differential circuit
breaker.
If the error occurs occasionally, the
probable cause is that the external
circuits have temporary faults.
The inverter automatically returns to
its normal operating state after the
error has been fixed.
ID13
GridFault
Check the voltage and
frequency of the grid
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.
