string
● Equalized voltage
14.1 V x Number of
batteries (tolerance
±1%)
● Float voltage 13.5
V x Number of
batteries (tolerance
±1%)
1. If the voltage drop
between the battery
string output
terminals and the
battery input terminals
at the UPS side is
greater than 1% of the
battery string voltage,
check whether the
cable between the
battery string and the
UPS is excessively
long, or the cable
diameter is excessively
small.
2. Check whether the
equalized charging
voltage and float
charging voltage are
correctly set for the
UPS.
3. If the fault persists,
contact Huawei
technical support.
