Installation time
A battery maintenance reminder is displayed when the maintenance time (counted from
the installation time) comes.
Maintenance period (d)
Interval for reminding users of battery maintenance.
Battery type
Set the battery type based on actual conditions. Currently, only lead-acid batteries are
supported.
Chg. cur. limiting coef. (C10)
Charging current limit, which is a multiple of the battery capacity. The value can be
0.05–0.15, 0.1 by default.
Cell float voltage (V/cell)
Set the float voltage. The value can be 2.23–2.27 V/cell, 2.25 V/cell by default. The
value is configurable in any mode.
Cell equalized volt. (V/cell)
Set the battery equalized voltage. The value can be 2.30–2.40 V/cell, 2.35 V/cell by
default. The value is configurable in any mode.
Transfer-to-equalized charging cur. Coef. (C10)
The battery enters equalized charge state when the battery current exceeds this parameter
value. The value range is 0.02–0.08, and the default value is 0.05.
SOC to start equalized charging (%)
When the SOC is lower than the specified value, batteries enter the equalized charging
mode. The value range is 0–100, and the default value is 70.
Automatic equalized charging
When the value is Enable, the UPS automatically changes the battery management
status to equalized charging based on the charge current and float charge time.
Forced equalized charging protection time (h)
When batteries are continuously under float charging or hibernation, you can enable
forced equalized charging. When the forced equalized charging time reaches the value of
this parameter, float charging starts.
Equalized charging protection interval (d) and Scheduled equalized charging
interval (d)
