4 Freedom SW 230V Owner’s Guide
Introduction
Parallel Stacking
Parallel stacking allows two inverter/chargers to operate in parallel
thereby doubling the capacity in inverter mode. The two units
communicate over the network and intelligently share the load to
balance the load between the two units. The Master unit broadcasts
pulses on the Xanbus network to synchronize operation between the
other paralleled unit. When AC loads are present, both units
produce power, effectively sharing the load. When Search mode is
enabled, only the Master unit produces the AC output.
Stack Charging
Dual units 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, both 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 units 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 both units capable of
equalization charging, only those units perform an equalize cycle
after absorption. The other unit transitions to float (if three-stage
charging is selected) or transitions 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 (or shore power) to temporarily assist power loads
with large start-up demands such as air conditioners, water pumps
etc. A Xanbus AGS is not required for this feature to work when
shore power is present to assist the Freedom SW 230V but the AGS
is needed if a generator were to be used in assisting the Freedom
SW 230V.
When the
Gen Support mode is enabled and the generator’s or
shore power’s current capacity defined (in amps), the inverter will
come on-line and assist the generator or shore power with starting
and operating the load (drawing power from the battery). The
battery bank must be well charged in order for the inverter to engage
this mode. For more details, see “Generator Support” on page 57.
