Default Value Value Range
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.
Undertemp.

(°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.

are
used to check whether the cells in
each battery string have the same
charge voltage and discharge
voltage. When a value exceeds
the specified range, an alarm is
generated.
The calculation formula is
(Charge/Discharge voltage –
Average voltage)/Average
voltage x 100%.
