) 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).
To set the
Max Chg Rate
(%) setting in each Freedom SW 3524-
230:
1. Divide the
maximum
allowable charger output current of 75A
by the Freedom SW 3524-230’s maximum charge capacity of
90A.
So, 75
/
90, gets an approximate value of 0.83 (or 83%)
which can be set exactly to 83%.
2. Set the
Max Chg Rate
(%)
setting to
83
which means 83%.
In this example, the
actual
output current is limited to 83% of
90A which is 74A. Therefore, the
actual
System Total BULK
output current
comes out to just under 150A.
