Examples
Example 1:
System composed of two stacked
Auto Power
20
00
s. Each
$XWR3RZHU
has a maximum charge capacity
of 100A.
The industry’s commonly accepted practice suggests a typical
Flooded battery bank capacity (
&
) of 400Ah should not be
charged beyond 25% of its capacity (100A). Therefore, when
configuring the two stacked
$XWR3RZHU
chargers, each
charger may have a
PD[LPXP
allowable charger output
current of 50A (400
[
25%
[
1
/
2
) into the common battery
bank as described in the Calculations section. Also, the
System Total BULK
output current
is calculated as 100A
(50A + 50A).
To set the
0D[&KJ5DWH
(%) setting in each
Auto Power 2000
:
1.
Divide the
PD[LPXP
allowable charger output current of 50A
by the
Auto Power 2000's
maximum charge capacity of 100A.
So, 50
100, gets an approximate value of 0.5 (or 50%).
2.
Set the
0D[&KJ5DWH
(%)
setting to
which means 50%.
In this example, the
actual
output current is limited to 50% of
100A which is 50A. Therefore, the
actual
System Total
BULK
output current
comes out to about 100A.
Example 2:
System composed of two stacked
$XWR3RZHU
30
s. Each
$XWR3RZHU
has a maximum charge capacity of
150A. The two stacked
$XWR3RZHU
inverter/chargers
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 400Ah should not be
charged beyond 25% of its capacity (100A). Therefore, when
configuring the two stacked
$XWR3RZHU
chargers, each
charger may have a
PD[LPXP
allowable charger output
current of 50A (400
[
25%
[
1
/
) into the common battery
bank as described in the Calculations section.

Also, the
System Total BULK
output current
is calculated as 100A
(50A + 50A).
To set the
0D[&KJ5DWH
(%) setting in each
Auto Power
30
00
:
Divide the
PD[LPXP
allowable charger output current of 50A
by the
$XWR3RZHU
s maximum charge capacity of 150A.
So,
50
150, gets an approximate value of 0.33 (or 33%)
which can be roughly reduced to 30%.
Set the
0D[&KJ5DWH
(%)
setting to
which means 30%.
In this example, the
actual
output current is limited to 30% of
150A which is 45A. Therefore, the
actual
System Total
BULK
output current
comes out just under 90A.
