Freedom SW-RVC Installation Guide
Example 2:
System composed of two stacked Freedom SW-RVCs. Each
Freedom SW-RVC has a maximum charge capacity of 150A. The
two stacked 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 (C) of 600Ah should not be charged
beyond 25% of its capacity (150A). Therefore, when configuring
the two stacked Freedom SW chargers, each charger may have a
maximum charger output current of 75A (that is, 600 x 25% x 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).
To set the
Max Chg Rate (%)
setting in each Freedom SW-
RVC:
1. Divide the maximum allowable charger output current of
75A by the Freedom SW-RVC’s maximum charge capacity
of 150A.
So, 75 / 150, gets an approximate value of 0.50 (or 50%)
which can be set exactly to 50%.
2. Set the
Max Chg Rate (%)
setting to 50 which means
50%.
In this example, the actual output current is limited to 50% of 150A
which is 75A. Therefore, the actual System Total BULK output
current comes out to about 150A.
