Basic Installation Procedures
Stacking Features
The Freedom EX 4000 supports series and parallel stacking
configurations. This gives the system engineer and/or
installer more options to work with when tailoring a system to
meet load demands that require higher surge capacity and/or
8000W continuous power rating.
IMPORTANT:
Contact Xantrex prior to stacking two Freedom EX 4000 units
together. Stacking configuration via USB is a required step to
enable stacking.
Series Stacking

In this configuration, two Freedom EX 4000 units may be
stacked to form a split-phase during Battery mode
120/240VAC,60 Hz, 33.3A, 8000W system required for high
surge appliances such as ranges, dryers, and air conditioners.
In Shore mode, charging capacity is doubled. See Series
Stacking on page 25.
Parallel Stacking
In parallel stacking mode, two Freedom EX 4000
inverter/chargers can be stacked to provide a combined
