Enable this feature 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 float voltage temperature compensation.
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.
Shallow dis. test
dis. ratio (%)
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.
Undertemp.
alarm thresh.
(°C) and
Overtemp. alarm
thresh. (°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 –20ºC to +5ºC and the default value is
–5ºC. The Overtemp. alarm thresh. can be set from 35ºC to 55ºC
and the default value is 50ºC.
