Description
If this parameter is set to Enable, the float
charging voltage is calibrated based on the
battery temperature when a battery
temperature sensor is connected. This
parameter is configurable in any mode.
Specifies the calibration coefficient during
float charging voltage temperature
compensation.
Specifies the reference temperature during
float charging voltage temperature
compensation.
If this parameter is set to Enable, the UPS
automatically changes the battery
management status to equalized charging
based on the charge current and float
charging time.
Batteries enter equalized charging state
when the battery currents exceed this
parameter value.
If the SOC is lower than the specified value,
batteries start equalized charging.
After batteries transfer from equalized
charging to float charging, if the batteries
do not discharge, equalized charging starts
only after the float charging time exceeds
Equalized charging protection interval.
After equalized charging is complete,
batteries automatically transfer to equalized
charging when the non-equalized charging
time exceeds Scheduled equalized
charging interval.
When batteries are under float charging or
hibernation for a long time, enable forced
equalized charging for the batteries. When
the forced equalized charging time reaches
Forced equalized charging protection
time, batteries automatically transfer to
float charging mode.
Specifies the maximum discharge time.
When the discharge time reaches this value,
the system powers off. If the time is set to 0
hours, battery discharge protection is not
implemented.
