Page 62: Calculations
Wiring Schematic For a Flooded type battery bank, the preferred charge rate (in Calculations Amps) is usually 10-15% of C where C = battery bank’s total Once installed and configured, each Freedom SW-RVC charger in Amp-hour capacity. However, the industry-accepted maximum the dual configuration should be set to its own bulk charge current charge rate is 25% of C.
Page 63: Examples
Wiring Schematic maximum possible 150A charger capacity is set to a Max Chg Examples Rate of 100 (%) then its full 150A of current can be delivered into Example 1: the battery bank. However, if this is too high, the installer/operator System composed of two stacked Freedom SW-RVCs.
Page 64 Wiring Schematic 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).
Page 65: Battery Information
BATTERY INFORMATION Battery Capacity About Amp-hours A number of different standards are used to rate battery energy Battery size or capacity is just as important as the battery type storage capacity. Automotive and marine starting batteries are selected for use with the Freedom SW-RVC. The batteries are normally rated in cranking amps.
