TROUBLESHOOTING HANDLING
SOFAR 1100...3300TL-G3 77
The input current is too
high and has caused an
unrectifiable error
ID74-ID77 are internal inverter
errors, 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.
The EEPROM cannot be
recovered
The EEPROM cannot be
recovered
The grid relay has a
permanent error
The inverter has derated
itself due to the
temperature being too
high
Ensure that the installation position
and method both comply with the
necessary requirements of this
user manual. Check whether the
ambient temperature at the
installation location exceeds the
upper limit value. If so, improve the
ventilation in order to reduce the
temperature.
The inverter has derated
itself due to the grid
frequency being too high
The inverter automatically reduces
the output power when the
frequency of the electrical grid is
too high. Ensure that the grid
frequency is within the permissible
range.
The inverter has derated
itself through the remote
control
The inverter logs ID83 when the
remote power is reduced. Check
the wiring of the remote control
input and output signal connection
on the communication board
