Description
equalized charging interval is 30 to 180 and the default value is
60.
Description
If this parameter is set to Enable, the float voltage is calibrated based
on the battery temperature when a battery temperature sensor is
connected. The parameter is configurable in any mode. The default
value is Enable.
Calibration coefficient during float voltage temperature compensation.
The value range is 0.0 to 6.0. The default value is 3.3.
Set the maximum battery discharge time. When the discharge time
reaches this value, the UPS powers off. The battery discharge time
can be set only to 0 hours or a value only in the range of 16–48 hours.
If the time is set to 0 hours, battery discharge protection is not
implemented. The default value is 24 hours.
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.
Set the proportion of the discharge capacity to the total discharge
capacity. The value can be 10%–50%, and is 20% by default. The
value is configurable in any mode.
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
