Set the battery equalized voltage. The value can be 2.30–2.40 V/cell, 2.35 V/cell by
default. The value is configurable in any mode.
Transfer-to-equalized charging cur. Coef. (C10)
The battery enters equalized charge state when the battery current exceeds this parameter
value. The value range is 0.02–0.08, and the default value is 0.05.
Automatic. equalized charging
When the value is
Enable
, the UPS automatically changes the battery management
status to equalized charge based on the charge current and floating charge time.
Forced equalized charging protection time (h)
When batteries are continuously under float charging or hibernation, you can enable
forced equalized charging. When the forced equalized charging time reaches the value of
this parameter, float charging starts.
Equalized charging protection interval (d)
and
Scheduled equalized charging
interval (d)
After batteries transfer from equalized charging to float charging, if the batteries do not
discharge, equalized charging starts only after the float charging time reaches
Equalized
charging protection interval
. After equalized charging is complete, scheduled equalized
charging starts when the non-equalized charging time exceeds
Scheduled equalized
charging interval
.
Float volt. temp. comp.
Option to correct the float voltage based on the battery temperature when a battery
temperature sensor is connected. The value is configurable in any mode.
Float volt. temp. comp. coef. (mV/°C·
cell)
Correction coefficient during floating voltage temperature compensation.
Max. batt. dis. time (h)
Set the maximum discharge time. When the discharge time reaches the value, the UPS
powers off. The value can be 16–48 hours, 24 hours by default.
Sched. shallow dis. test
When certain conditions are met, the charger shuts down, and batteries supply power to
loads. The system records the battery discharge data as the reference for battery capacity
and lifespan.
Shallow dis. test dis. ratio (%)
Set the proportion of the discharge capacity to the total discharge capacity. The value can
be 10%–50%, 20% by default. The value is configurable in any mode.
Undertemp. alarm thres. (°C)
and
Overtemp. alarm thres. (°C)
Battery temperatures can be monitored in a timely manner. If a battery overtemperature
alarm is detected, the charging current limit decreases to 0.03 CA. Battery charging stops
if a battery overtemperature protection alarm (when the temperature reaches the high
temperature threshold plus 3°C) is generated. The
Undertemp. alarm thresh.
can be set
from -20°C to +5°C and the default value is –5°C. The
Overtemp. alarm thresh.
can be
set from 35°C to 55°C and the default value is 50°C.
Backup time warning
and
Remain. cap. warning
When the first two parameters are set to
Enable
, an alarm is generated when the backup
time or remaining capacity is less than the alarm threshold.
