4 Freedom SW Owner’s Guide
Introduction
Stack Charging
Multiple Freedom SWs synchronize charging stages to ensure efficient
charging of the battery bank. When a single unit transitions from bulk to
absorption so do all other units. In absorption, all units must complete the
absorption stage before transitioning to the next stage. Note that units do
not load share when charging except during the bulk stage. The Freedom
SWs stop sharing charge current just before completing the bulk stage. The
units do not share charge current during the absorption and float stages.
Each unit charges batteries based on the Max Charge Rate setting and active
internal (temperature-based) deratings.
If equalization is enabled on one or more devices capable of equalization
charging, only those devices perform an equalize cycle after absorption.
Other devices transition to float (if three-stage charging is selected) or
transition to AC pass-through (if two-stage charging is selected).
Generator Assist
The Freedom SW Series of inverter/chargers can operate in tandem with a
generator to temporarily assist power loads with large start-up demands
such as air conditioners, water pumps etc. A Xanbus AGS must be installed
in the system in order for this feature work.
When this mode is enabled and generator capacity defined, the inverter will
come on-line and assist the generator when the generator reaches its
capacity. The battery bank must be well charged in order for the inverter to
engage this mode. For more details, see “Gen Support” on page 53.
