Procedure
Step 1 Set the mode. On the LCD, choose System Info > Settings > System Settings and
set Working mode to S-ECO. The information indicating that the UPS works in S-
ECO mode is displayed on the LCD.
Step 2 Set parameters.

becomes normal, the UPS goes back to the S-ECO mode or other power
supply modes.
S-ECO mode VFD: When the input voltage is of good quality and fluctuates
slightly and the load is mainly linear, the load current THDi is less than the
preset value (10% by default) and the power factor is greater than 0.95. In
this case, the UPS automatically enters the S-ECO mode VFD, provides power
supply at efficiency up to 99%, and achieves good input current THDi. When
the bypass input is disconnected or the voltage is abnormal, the UPS
continuously transfers to normal mode.
S-ECO mode VI: When the input voltage is of good quality and fluctuates
slightly and the load is mainly non-linear, the load current THDi is greater
than the preset value (10% by default) and the power factor ranges from 0.5
to 0.95. In this case, the UPS automatically enters VI mode. The inverter
compensates for harmonics and reactive power of the load current, which
delivers the 98.5% efficiency together with a higher input power factor and a
lower input current THDi. When the bypass input is disconnected or the
voltage is abnormal, the UPS uninterruptedly transfers to normal mode.
The S-ECO mode requires the support of the hardware of both the power
module and bypass module. If the system runs in a mode other than S-ECO
and the hardware does not support the S-ECO mode, the system can only
select the ECO mode. If the system runs in S-ECO mode but the hardware is
changed and does not support it, the system displays the message "The
current hardware does not support S-ECO. The system will work in ECO
mode." After you tap OK, the system transfers to the ECO mode (5 ms
interruption may occur during the transfer of the ECO mode). If the hardware
supports this mode but the conditions are not met, the system works in
normal mode.
