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.
Calibration coefficient during float voltage
temperature compensation.
Indicates the reference temperature during
temperature compensation of the float charging
voltage.
If this parameter is set to Enable, the UPS
automatically changes the battery management
status to equalized charge based on the charge
current and float charge time.
The battery enters equalized charge state when
the battery current exceeds 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 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.
When batteries are continuously under float
charging or hibernation, enable forced
equalized charging. When the forced equalized
charging time reaches the value of this
parameter, batteries automatically transfer to
float charging mode.
Set the maximum battery discharge time. When
the discharge time reaches this value, the UPS
powers off. If the time is set to 0 hours, battery
discharge protection is not implemented.
If the mains is not functioning normally, the
UPS will transfer to battery mode. When
batteries reach the EOD threshold, the bypass is
