Solution
28
DciOCP
The DC current is too high
Check the setting of the MPPT
input mode (parallel
mode/independent mode) of the
inverter and correct if required.
29
SwOCPInstan
The grid current is too
high
Internal inverter error, switch the
DC switch OFF, wait 5 minutes and
then switch the DC switch ON.
Check whether the error has been
rectified. If not, please contact the
technical support department.
30
SwBOCPInst
ant
The input current is too
high
Check whether the input current is
higher than the maximum
permissible input current of the
inverter, then check the input
cables. If both are correct, please
contact the technical support
department.
33
Overload
Reflux overload timeout
Check whether the power is
outside the permissible range. If so,
set the power to the correct range.

The sample value of the
grid voltage between the
master DSP and the slave
DSP is not consistent.
ID49-ID55 are internal errors of the
inverter. Switch the DC switch OFF,
wait 5 minutes and then switch the
DC switch ON. Check whether the
error has been rectified. If not,
please contact the technical
support department.
