ID15-ID24 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.

The bus voltage Is
too low
If the PV array configuration is correct (no
ID05 fault), the possible cause is that the solar
irradiance is too low. inverter automatically
returns to normal operating status after the solar
irradiance returns to normal level.

ID26-ID27 are internal faults of inverter,
