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)
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.
ID30
SwBOCPInstant 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.
ID33
Overload
Reflux overload
time out
Check if the load power is out of range, and
if so, adjust the power to the correct range.

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
