IpvUnbalance Input current is not
symmetrical
Check the setting of the MPPT
input mode (parallel
mode/independent mode) of the
inverter and correct it as well if
required.

Earthing error
If the error occurs occasionally,
then external factors may be to
blame. The inverter automatically
returns to its normal operating
state. If the error occurs frequently
and lasts for a prolonged period,
check whether the insulation
resistance between the PV
generator and earth (ground) is too
low and examine the PV cable
insulation.

HwBoostOCP The input current is too
high and has triggered the
hardware protection
Check whether the input current is
higher than the maximum
permissible input current of the
inverter. Check the input cables. If
both are correct, please contact the
technical support department.

HwAcOCP
The grid current is too
high and has triggered the
hardware protection
ID15-ID24 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.
