Stacking Features
This guide for use by qualified installers only.
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 46.
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.
