Remarks
This parameter is set according to the actual
requirements.
automatic: The power system automatically
adjusts the charging mode of batteries according
to the status of the battery set.
equalizing: The battery is charged forcibly so as
to quickly compensate for the lost capacity of the
battery.
floating: The battery adjusts charging/
discharging when it is in saturation.
Default: automatic.
This parameter is set according to the actual
requirements. When setting the equalized
charging voltage of the battery, make sure that DC
overvoltage - 1 V > equalized charging voltage >
float charging voltage + 2 V, and that DC
undervoltage > load power-off voltage > battery
power-off voltage.
Default: 56.5 V.
This parameter is set according to the actual
requirements. When setting the float charging of
the battery, make sure that DC overvoltage - 1 V
> equalized charging voltage > float charging
voltage + 2 V, and that DC undervoltage > load
power-off voltage > battery power-off voltage.
Default: 53.5 V.
This parameter is set according to the actual
requirements. In the normal state, the current of
the power supply is not limited. The current-
limiting function is enabled when the charging
current of the battery set > current-limiting
coefficient x nominal capacity of the battery set.
Default value: 0.15.
This parameter is set according to the actual
requirements. If the continuous float charging
duration of the rectifier unit exceeds the preset
equalized charging interval, the battery enters the
equalized charging state.
Default: 60 days.
