Freedom SW 3K2K 230V InvChg Install Guide.book Page 44 Friday, June 20, 2014 9:11 AM Stacking Features Neutral Wiring for Stacked Inverters Due to the neutral ground switching design of the Freedom SW Inverter/charger, it is mandatory that the AC INPUT and AC OUTPUT Neutrals be isolated from one another.
Freedom SW 3K2K 230V InvChg Install Guide.book Page 45 Friday, June 20, 2014 9:11 AM Verify all DC and AC connections. Check Xanbus network connections and ensure that terminators are installed at devices at each end of the network. The simplest system includes a Xanbus SCP, the two Freedom SW 230V inverter/chargers to be stacked and two Xanbus terminators. For both units to operate in stacked configurations, a Master and Slave have to be assigned.
Freedom SW 3K2K 230V InvChg Install Guide.book Page 46 Friday, June 20, 2014 9:11 AM Stacking Features Search Mode Operation in Parallel Stacking When two inverter/chargers are stacked for parallel operation, search mode behavior on the Slave unit is modified and is dependent on how much total load is on the system. Disabling Search Mode on the Master Unit In parallel stacking, search mode on the Master unit will not function properly.
Freedom SW 3K2K 230V InvChg Install Guide.book Page 47 Friday, June 20, 2014 9:11 AM Stacking Features Charger Settings in a Dual Freedom SW Configuration The battery bank capacity (C) is the bank’s total Amp-hour capacity, which is best determined by a qualified RV electrical technician. The Max Chg Rate depends on the battery manufacturer's maximum charge rate for the specific battery model being used to construct the bank.
Freedom SW 3K2K 230V InvChg Install Guide.book Page 48 Friday, June 20, 2014 9:11 AM Stacking Features each parallel branch of batteries. Therefore, the above generalizations of maximum charge rate (%) can be made for the entire battery bank. The Freedom SW 230V’s Max Chg Rate (%) setting defaults to 100 (adjustable from 0 to 100).
Freedom SW 3K2K 230V InvChg Install Guide.book Page 49 Friday, June 20, 2014 9:11 AM The industry’s commonly accepted practice suggests a typical Flooded battery bank capacity (C) of 400Ah should not be charged beyond 25% of its capacity (100A). Therefore, when configuring the two stacked Freedom SW chargers, each charger may have a maximum allowable charger output current of 50A (400 × 25% × 1/2) into the common battery bank as described in the Calculations section.
Freedom SW 3K2K 230V InvChg Install Guide.book Page 50 Friday, June 20, 2014 9:11 AM Stacking Features Example 4: System composed of two stacked Freedom SW 3524230s. Each Freedom SW 3524-230 has a maximum charge capacity of 90A. The two stacked Freedom SW 3524-230 inverter/chargers connected to the same battery bank can possibly produce a total of 180A.
