7.3.3.4. User settings.
Users can adjust the output voltage to above or below the
stipulated voltage range. The full scale is 1 V. It is also possible
to adjust the voltage and frequency range of the Bypass. This
screen is shown in the following Fig. 79:

7.3.3.5. Battery settings.
The battery settings must be done after the first shutdown or
when a change has been made to them. This can be configured
through the LCD control panel, Fig. 81 and Fig. 82, or through
the control software, Fig. 83.
ˆ
Battery type setting: this setting can only be done
using the monitoring software. The system currently
supports lead acid and lithium batteries (LFPB).
ˆ
Battery number setting:
–
For lead-acid batteries: The rated voltage of an
element is 12 V - consists of 6 cells of 2 V each.
For setting, if the number of batteries is 40, this
means that there are 40 elements:
±
20 for both
+ and - signs.
In the case of 2V cells (usually for large capacities),
the number of batteries should match the number
of elements, since the number of cells will be 240
(6 * 40) or
±
120 for both + and - signs.
The setting range for the number of batteries is
between 32 and 44 (even number). The available
capacity of the UPS, however, should be around
80 or 85% of its capacity when configured with a
number of batteries between 32 and 34 elements.
–
For lithium batteries: The voltage of each cell of this
type of battery is 3.2 V. Therefore, if 40 lead-acid
battery elements are used, in the case of lithium
batteries, the number will be 150 (12/3.2 = 3.75 x
40 = 150) or, in other words,
±
75 elements for both
+ and - signs.
The setting range for the number of batteries is
between 140 and 180 elements. The end of backup
voltage will be 360V and the highest voltage 620 V.
ˆ
Battery capacity setting:
The user can adjust the capacity value of a battery
element. For example, if the system is configured
with 40 elements of 12 V/100 Ah, the battery capacity
should be 100Ah, and if with 240 elements of 2 V/1000
Ah, it should be 1000 Ah.
In the case of specifying more than one branch of
batteries in parallel, the value of the overall capacity
should be that of one branch by the number of branches.
For example, if we configure 2 branches of 40 elements
of 12V/100 Ah, the resulting capacity would be 200 Ah.
The system limits the charging current according to the
battery capacity. For lead-acid batteries, the charging
current is 0.2C, and for lithium batteries it will be
0.3C. For example, for a 20-slot UPS configured with
40 elements of 12 V/500 Ah, the UPS will be able to
supply a maximum charging current of 192 A but, due
to the charging current limit (0.2C), it will not exceed
100 A (0.2*500).
ˆ
Float and quick charging voltage setting:
For quick charging, the system charges the battery at
constant current. Once complete, the system will go
into float charging.
For lead-acid batteries, the default float voltage is 2.25
V/element and the quick charging voltage is 2.35 V/
element.
For lithium batteries, the float and quick charging
voltage is 3.45V/element.
ˆ
End of backup voltage setting (EOD voltage):
An EOD voltage of 0.6C is given when the discharge
current is greater than 0.6C; an EOD voltage of 0.15C
is given when the discharge current is less than 0.15C.
The EOD voltage will decrease linearly while it is be-
tween 0.15C and 0.6C, as shown in the following chart:
EOD voltage 0.15C
EOD voltage 0.6C
Fig. 80. EOD end of backup voltage behaviour.
For lead-acid batteries, the suggested voltage is 1.65
V/cell to 0.6C and 1.75 V/cell to 0.15C.
For lithium batteries, 2.7 V/cell for both.
