Stacking Features
Parallel Stacking
Allows the inverter and charger capacity of a system to be doubled.
Parallel-stacked inverter/chargers can operate from different battery
banks, meaning each unit is connected to its own battery bank.
However, it is highly recommended to only use a single battery
bank. See “DC Connections for Stacked Inverters” on page 43.
Do NOT connect a stacking cable to the STACKING port on the
front panel of a Freedom SW 230V to configure two units for
parallel stacking. The port is reserved for future use.
