ID26-ID27 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
DASS TECH technical support.

If the PV array configuration is correct (no ID5 fault),
the possible cause is that the solar irradiance is too
low. DASS TECH inverter automatically returns to
normal operating status after the solar irradiance
returns to normal level.
Check the input mode(parallel mode/ independent
mode) setting of DASS TECH inverter according to
Section 4.5 of this user manual.
If the input mode is correct, 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 DASS TECH technical support.
Internal faults of

Check whether the input current is higher than the
maximum input current of DASS TECH inverters,
then check the input wiring, if both are correct, please
contact DASS TECH technical support.
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
DASS TECH technical support.

Please check whether grounding cable connected
well or not
Check the insulation resistance between the PV array
and earth(ground), if a short circuit occurs, rectify the
fault.
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 temperature.
Check whether the ID90~ID92 fault (fan fault) exist,
if yes, please replace the corresponding fan.
ID65-ID70 are internal faults of
