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.
The bus voltage is
not balanced
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)
The grid current is
too high
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.
The input current is
too high
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.
Check if the load power is out of range, and
if so, adjust the power to the correct range.
The grid voltage
sampling value
between the master
DSP and slave DSP
is not consistent
ID49-ID55 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.
