Configuring the Freedom SW using the SCP

by setting each charger’s “Max Charge Rate”% setting to deliver ½ of the desired total battery bank charge rate of 100 A, i.e. In this example, each charger “Max Charge Rate” should be set to at most “50%” therefore 50% x (charger max capacity of 100 A) = 50 Amps actual max output, therefore since we have two chargers 50 A + 50 A = 100 A which is the max bulk current this battery bank can accept.

Example 2: The Freedom SW3012 includes a 150 A charger, when using two stacked Freedom SW3012 inverter/chargers connected to the same bat- tery bank, a total of 300 A of bulk charging is possible.

In a system composed of two stacked FSW3012’s. Industry commonly accepted practice suggests, a typical Flooded battery bank of capacity (C) 400Amp-hours should not be charged at a rate in excess of 25% of “C” i.e. 25% x 400(Ah) = 100 Amps. Therefore, when configuring the two stacked Freedom SW chargers, each charger must be limited to contributing max

50 A each into the common battery bank. This is accomplished by setting each charger’s “Max Charge Rate”% setting to deliver ½ of the desired total battery bank charge rate of 100 A. i.e. in this example, each charger “Max Charge Rate” should be set to “33%” x (charger max capacity of 150 A) = 50 A actual max output, therefore 50 A + 50 A = 100 A which is the max bulk current this battery bank can accept.

Example 3: The Freedom SW 3012 includes a 150 A charger, when using two stacked Freedom SW3012 inverter/chargers connected to the same bat- tery bank, a total of 300 A of bulk charging is possible.

In the above system composed of two stacked FSW3012’s. Industry commonly accepted practice suggests, a typical Flooded battery bank of capacity (C) 1000 Amp-hours should not be charged at a rate in excess of 25% of “C” i.e. 25% x 1000(Ah) = 250 Amps. Therefore, when configuring

the two stacked Freedom SW chargers, each charger must be limited to contributing max 125 A each into the common battery bank. This is accomplished by setting each charger’s “Max Charge Rate”% setting to deliver ½ of the desired total battery bank charge rate of 250 A, i.e. in this example, each charger “Max Charge Rate” should be set to “83%” x (charger max capacity of 150 A) = 125 A actual max output, therefore 125 A + 125 A = 250 A which is the max bulk current this battery bank can accept.

Example 4: The Freedom SW 3024 includes a 75 A(@24 V) charger, when using two stacked Freedom SW3024 inverter/chargers connected to the same battery bank, a total of 150 A(@24 V) of bulk charging is possible. Industry commonly accepted practice suggests, a typical Flooded battery bank of capacity (C) 600 Amp-hours (@ 24 V) should not be charged at a rate in excess of 25% of “C” i.e. 25% x600(Ah) = 150 Amps (@24 V). Therefore, when configuring the two stacked Freedom SW chargers, each charger must be limited to contributing max 75 A (@24 V) into the com- mon battery bank. This is accomplished by setting each charger’s “Max Charge Rate”% setting to deliver ½ of the desired total battery bank charge rate of 150 A. i.e. in this example, each charger “Max Charge Rate” should be set to “100%” x (75 A charger max capacity) = 75 A actual max output, therefore 75 A + 75 A = 150 A which is the max bulk current this battery bank can accept.
