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, If it’s incorrect, change it
according to Section 6.3 (A) 10.Set Input
mode of this manual.
ID29
SwOCPInstan
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.

than the maximum input current of
inverters, then check the input wiring, if
both are correct, please contact technical
support.
