3 STACKING FEATURES The Freedom SWs can support two stacking configurations. This gives the system engineer and/or installer more options to work with when tailoring a system to meet load demands. Multiple inverter/chargers of different power levels can be installed in a system as stand alone, parallel stacked, or series stacked.
Parallel Stacking Figure 21 Parallel Stacking Using Two Freedom SW 12V 3012 Parallel Stacking units A parallel stacking configuration allows the inverter and charger Main Distribution Panel capacity of a system to be doubled. Parallel-stacked Master unit NEUTRAL inverter/chargers can operate from different battery banks, WARNING: INCORRECT BATTERY meaning each unit is connected to its own battery bank.
Series Stacking Series Stacking Figure 23 Series Stacking Using Two Freedom SW 12V 3012 units A series stacking configuration allows two inverters to be Main Master unit Distribution Panel configured to produce 120 and 240 volts AC, also known as, a WARNING: INCORRECT BATTERY NEUTRAL single-phase three-wire configuration.

Neutral Wiring for Stacked Inverters Neutral Wiring for Stacked Configuring System for Inverters Stacked Operation Due to the neutral ground switching design of the Freedom SW Verify all DC and AC connections. Check Xanbus (or RV-C) Inverter/charger, it is mandatory that the AC INPUT and AC network connections and ensure that terminators are installed at OUTPUT Neutrals be isolated from one another.
Load Sense in Series Stacking Load Sense in Series Stacking Wiring Schematic When configured for 120/240-volt series stacking, each NOTE: Please refer to the Stacking Configuration sheet that inverter/charger operates independently in search mode and shows the wiring schematic employed between two Freedom attempts to detect loads connected to its terminals only.
Charger Settings in Stacked Configuration Charger Settings in Stacked Calculations Once installed and configured, each Freedom SW charger in the Configuration dual configuration should be set to its own bulk charge current The Freedom SW includes a maximum charger amperage limit as follows: depending on the model.
Charger Settings in Stacked Configuration Examples Example 1: System composed of two stacked Freedom SW 12V 3012s. Each Freedom SW 12V 3012 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 400Ah should not be charged beyond 25% of its capacity (100A).
