Stacking Features
Example 3:
System composed of two stacked
$XWR3RZHU
=
s. Each
$XWR3RZHU
has a maximum charge capacity of
100A. The two stacked
$XWR3RZHU
I
nverter/
C
hargers
connected to the
same battery bank
can possibly produce a total of
200A.
The industry’s commonly accepted practice suggests a typical
Flooded battery bank capacity (
&
) of 1000Ah should not be
charged beyond 25% of its capacity (250A). Therefore, when
configuring the two stacked
Auto Power
chargers, each
charger may have a
PD[LPXP
charger output current of 125A
(that is, 1000
[
25%
[
1
/
) into the common battery bank as
=
described in the Calculations section.

Also, the System Total
BULK
output current
is calculated as 250A (that is, 125A +
125A).
To set the
0D[&KJ5DWH
(%) setting in each
$XWR3RZHU
:
=
Divide the
PD[LPXP
allowable charger output current of 125A
by the
$XWR3RZHU
’s maximum charge capacity of 100A.
So, 125
100, gets an approximate value of 1.25 (or
125%) which means that even when the charger is
operating at 100% full power, the battery bank can more
than adequately accept the current the charger is
delivering.
Set the
0D[&KJ5DWH
(%)
setting to
which means 100%.
There is no setting beyond 100%.
In this example, the
actual
output current is limited to 100%
of 100A which is 100A. Therefore, the
actual
System Total
BULK
output current
comes out to 200A.
Example 4:
System composed of two stacked
Auto Power
3000
s. Each
$XWRSRZHU
has a maximum charge capacity
of 150A. The two stacked
$XWRSRZHU
I
nverter/
C
hargers connected to the
same battery bank
can possibly
produce a total of 300A.
The industry’s commonly accepted practice suggests a typical
Flooded battery bank capacity (
&
) of 600Ah should not be
charged beyond 25% of its capacity (150A). Therefore, when
configuring the two stacked
$XWR3RZHUF
hargers, each
charger may have a
PD[LPXP
charger output current of 75A
(that is, 600
[
25%
[
1
/
2
) into the common battery bank as
=
described in the Calculations section. Also, the System Total
BULK
output current
is calculated as 150A (that is, 75A +
75A).
