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.
SOFAR inverter automatically reduce the output
power when the frequency of electrical grid is too
high.
SOFAR inverter records ID83 in case of remote power
derating operation. Check the wiring of remote input
and output control signal port on the communication
board according to Section 4.4 of this user manual.
SOFAR inverter records ID84 in case of remote
shutdown operation. Check the wiring of remote input
and output control signal port on the communication
board according to Section 4.4 of this user manual.

If the PV array configuration is correct (no ID5 fault),
the possible cause is that the solar irradiance is too
low. SOFAR inverter automatically returns to normal
operating status after the solar irradiance returns to
normal level.
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.
