Max. voltage parameter
−
Upper threshold for the ECO voltage. In ECO mode, when the difference between
the bypass voltage and the rated voltage is greater than this value, the system
determines that the ECO voltage is abnormal and transfers to normal mode. The
values include 5%, 6%, 7%, 8%, 9%, and 10% (default). The parameter is
configurable after the inverter shuts down.
− Min. voltage parameter
Lower threshold for the ECO voltage. In ECO mode, when the difference between
the bypass voltage and the rated voltage is greater than this value, the system
determines that the ECO voltage is abnormal and transfers to normal mode. The
values include 5%, 6%, 7%, 8%, 9%, and 10% (default). The parameter is
configurable after the inverter shuts down.
− Frequency range parameter
ECO frequency range. In ECO mode, when the difference between the bypass
frequency and the rated frequency is greater than this range, the system determines
that the ECO frequency is abnormal and transfers to normal mode.
The frequency range must be less than the current bypass frequency range. The
values include ± 0.5 Hz, ± 1 Hz, ± 2 Hz (default), and ± 3 Hz. The parameter is
configurable after the inverter shuts down.
− Single UPS ECO parameter
Determine whether to support ECO mode on a single UPS (ECO mode is not
supported in a parallel system). The values include Disabled and Enabled. The
default value is Disabled. The parameter is configurable after the inverter shuts
down.

 In single UPS mode, primary loads connect to sL, and secondary loads connect to pL.
 In single UPS mode, if power segment is enabled, pL is disconnected and sL continues with power
output when an overload occurs.
 In a parallel system, UPS AC output power cables connect to pL.
− Dis. time. thres. parameter
pL terminal loading time in battery mode when power segment (not supported in a
parallel system) is enabled. In battery mode, if the discharge time exceeds this value,
the UPS disconnects from secondary loads. The value ranges from 0 to 999, in units
of minutes. The default value is 30. The parameter is configurable in non-battery
mode or non-battery ECO mode.
The UPS2000-G-15 kVA/20 kVA supports battery ECO mode only in the case of two mains inputs. In
battery ECO mode, the bypass supplies power to the UPS, and batteries are used as backup power. If the
bypass is abnormal, the UPS transfers to battery mode.
