Battery Setting
Battery parameter settings impact battery maintenance, battery lifespan, and UPS
discharge time. When you set battery parameters, note the following:
● Retain default settings for Chg. cur. limiting coef. and Cell float voltage. Only
● When you set parameters, ensure the following: Chg. cur. limiting coef. >
● Single batt. float chg. voltage deviation alarm thres. and Single batt. dis.

Description
Specifies whether to start
bypass mode when
overtemperature occurs.
Enable or disable the light
load bypass current
imbalance alarm. If this
parameter is set to Enable,
the load is light (less than
30% load), and the load rate
of a certain rack is less than
10%, the system will
generate a bypass current
imbalance alarm and cannot
enter the ECO mode. If this
parameter is set to Enable,
the preceding detection is
not performed. Whether the
bypass current is imbalanced
does not affect the ECO
bypass mode.
NO TICE
professional maintenance personnel are allowed to change the settings.
Transfer-to-equalized charging cur. coef.
voltage deviation alarm thres. are used to check whether the batteries in
each battery string have the same charge voltage and discharge voltage. When
a value exceeds the specified range, an alarm is generated. The calculation
formula is (Charge/Discharge voltage – Average voltage)/Average voltage x
100%. The charge/discharge voltage and average voltage are obtained from
the BMU. If the BMU is not configured, these two parameters do not need to
be set.
