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.

The inverter temp
is too high
Ensure the installation position and
installation method meet the requirements of
Section 3.4 of this user manual.
Check whether the ambient temperature of
the installation position exceeds the upper limit.
If yes, improve ventilation to decrease the
