Voltage
parameter
Set the battery float voltage. The value ranges from 2.25 V/cell to 2.30 V/cell. The
default value is 2.25 V/cell. The parameter is configurable in any mode.
−
Temp. comp. coef.
parameter
Set a float voltage correction coefficient based on the battery temperature when a
battery temperature sensor is connected. The value ranges from 0.0 mV/º
C*cell to
6.0 mV/º
C*cell. The default value is 3.3 mV/º
C*cell. The parameter is configurable
in any mode.

Max. time
parameter
Set the maximum discharge time. When the discharge time reaches the value, the
UPS powers off. The value ranges from
0Hour
to
24Hour
. The default value is
16Hour
. If you set the value to
0Hour
, the discharge time is not limited. The
parameter is configurable in non-battery mode or non-battery ECO mode.
If you expect the battery discharge time to be greater than 24 hours, set
Max. time
to 0 hour.
Otherwise, the system may power off.
If you set
Max. time
to 0 hour, the battery string may remain in the small-current discharge state
according to the proportion of the battery capacity to the load power, which affects the battery
lifecycle.
−
EOD mode
parameter
Determine the power backup time. The values include
Backup time first
(ensures
system running and has a long backup time,
values),
Batt. protect first
(protects batteries and extends the battery lifespan,
shows the EOD setting values), and
Balanced mode
EOD setting values). The default value is
Backup time first
. The parameter is
configurable in non-battery mode or non-battery ECO mode. EOD is short for end
of discharge.
