Safety Information
ELECTRICAL SHOCK HAZARD
• Do not expose the Freedom SW to rain, snow, spray, or bilge water.
This inverter/charger is designed for marine applications only when
additional drip protection is installed in certain orientations. See the
installation guide for information.
• Do not operate the inverter/charger if it has received a sharp blow,
been dropped, has cracks or openings in the enclosure including if
the AC terminal cover has been lost, damaged, or will not close, or
otherwise damaged in any other way.
• Do not disassemble the inverter/charger. Internal capacitors remain
charged after all power is disconnected.
• Disconnect both AC and DC power from the inverter/charger before
attempting any maintenance or cleaning or working on any circuits
connected to the inverter/charger. The INVERTER ENABLE button
on the front panel does not function like a power switch that
energizes or de-energizes the unit arbitrarily. When AC and DC power
sources are connected and present, the unit is always energized.
• Do not operate the inverter/charger with damaged or substandard
wiring. Make sure that all wiring is in good condition and is not
undersized.
Failure to follow these instructions will result in death or serious injury.
FIRE AND BURN HAZARD
• Do not cover or obstruct the air intake vent openings and/or install in
a zero-clearance compartment.
• Do not use transformerless battery chargers in conjunction with the
inverter/charger due to overheating.
Failure to follow these instructions will result in death or serious injury.
EXPLOSION HAZARD
• Charge only properly rated (such as 12 V) lead-acid (GEL, AGM,
Flooded, or lead-calcium) rechargeable batteries because other
battery types may explode.
• Do not work in the vicinity of lead-acid batteries. Batteries generate
explosive gases during normal operation. See note #1.
• Do not install and/or operate in compartments containing flammable
materials or in locations that require ignition-protected equipment.
See notes #2 and #3.
• When using Lithium-Ion batteries, ensure that the battery pack being
used includes a certified Battery Management System (BMS) with
safety controls.
Failure to follow these instructions will result in death or serious injury.
iv Freedom SW Owner’s Guide
NOTES:
1. Follow these instructions and those published by the battery
manufacturer and the manufacturer of any equipment you intend to use
in the vicinity of the battery. Review cautionary markings on these
products and on the engine.
2. This inverter/charger contains components which tend to produce arcs
or sparks.
3. Locations include any space containing gasoline-powered machinery,
fuel tanks, as well as joints, fittings, or other connections between
components of the fuel system.
Precautions When Working With Batteries
BURN FROM HIGH SHORT-CIRCUIT CURRENT, FIRE AND
EXPLOSION FROM VENTED GASES HAZARDS
• Always wear proper, non-absorbent gloves, complete eye protection,
and clothing protection. Avoid touching your eyes and wiping your
forehead while working near batteries. See note #4.
• Remove all personal metal items, like rings, bracelets, and watches
when working with batteries. See notes #5 and #6 below.
• Never smoke or allow a spark or flame near the engine or batteries.
• Never charge a frozen battery.
Failure to follow these instructions can result in death or serious injury.
2. Always have someone within range of your voice or close enough to
come to your aid when you work near a lead-acid battery.
3. Always have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing, or eyes.
4. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters your eye, immediately flood it with running
cold water for at least twenty minutes and get medical attention
immediately.
5. Use extra caution to reduce the risk or dropping a metal tool on the
battery. It could spark or short circuit the battery or other electrical
parts and could cause an explosion.
6. Batteries can produce a short circuit current high enough to weld a ring
or metal bracelet or the like to the battery terminal, causing a severe
burn.
7. When removing a battery, always remove the negative terminal from
the battery first for systems with grounded negative. If it is grounded
positive, remove the positive terminal first. Make sure all loads
connected to the battery and all accessories are off so you don’t cause
an arc.
NOTES:
1. Mount and place the Freedom SW Inverter/Charger unit away from
batteries in a well ventilated compartment.

Precautions When Preparing to Charge
Precautions When Placing the Inverter/Charger
EXPOSURE TO CHEMICALS AND GASES HAZARD
• Make sure the area around the battery is well ventilated.
• Make sure the voltage of the batteries matches the output voltage of
the inverter/charger.
• Be careful to keep corrosion from coming into contact with your eyes
and skin when cleaning battery terminals.
Failure to follow these instructions can result in death or serious injury.
NOTES:
• Study and follow all of the battery manufacturer's specific precautions,
such as removing or not removing cell caps while charging, whether
equalization is acceptable for your battery, and recommended rates of
charge.
• For flooded non-sealed batteries, add distilled water in each cell until
battery acid reaches the level specified by the battery manufacturer.
This helps to purge excessive gas from cells. Do not overfill. For a
battery without removable cell caps, carefully follow manufacturer's
instructions.
RISK OF DAMAGE TO THE INVERTER/CHARGER
• Never allow battery acid to drip on the inverter/charger when reading
gravity, or filling battery.
• Never place the Freedom SW Inverter/Charger unit directly above
batteries; gases from a battery will corrode and damage the inverter/
charger.
• Do not place a battery on top of the inverter/charger.
Failure to follow these instructions can damage the unit and/or damage
other equipment.

Key Features
The Freedom SW Inverter/Charger is a true sine wave
inverter/charger that can be used for mobile, marine and
commercial applications. The Freedom SW Inverter/Chargers
are designed to operate with a wide variety of generators and
are capable of operating in parallel with a generator for short
durations to assist with starting large loads. The Freedom SW
is a convenient combination of an inverter, multistage battery
charger, and transfer switch in one electronic device.
• As an inverter, the Freedom SW provides true sine wave power
for your microwave, entertainment system, computer, and other
loads. This power is identical to the AC source provided from the
utility grid (power company).
• Some of the benefits of true sine wave power include
consistent cooking in your microwave, handling of
sensitive loads such as your TV set, dimmer switches, and
appliances with speed controls.
• Highly versatile platform capable of series stacking for
120/240V line configurations and parallel stacking to
increase power levels.
• High efficiency true sine wave output to power sensitive
electrical and electronic equipment.
• Surge capacity to start difficult loads like refrigerators or
• Power factor-corrected (PFC) input minimizes AC input current
• As a charger, it has high output, multistage charging

Introduction
Key Features Explained
Built-in Charge Formulas For the unit to perform at the
highest level, the batteries must be charged correctly. The
Freedom SW has optimized algorithms for flooded, gel, and
AGM batteries.
Battery Temperature Sensor Since battery temperature is
a key factor in correct charging, the charging formula must be
adjusted (automatically and in real time) according to the
actual battery temperature to ensure that batteries are fully
charged, but not overcharged. For this reason, a battery
temperature sensor is included with your Freedom SW and
has temperature compensated the charge formula.
Manual Equalization Over a period of time, the cells in a
flooded battery can develop uneven chemical states. This can
result in a weak (undercharged) cell which, in turn, can reduce
the overall capacity of the battery. To improve the life and
performance of a non-sealed, flooded battery, the Freedom
SW’s multistage charging cycle includes a manual equalize
mode that can be used, if recommended by the battery
manufacturer.
Dead Battery Charging Another feature that the Freedom
SW includes is dead battery charging. The Freedom SW—
unlike many chargers—has the ability to recharge batteries
even if the battery voltage is very low (5 volts for Freedom
SW 2012 / 3012 units and 12 volts for Freedom SW 2024 /
3024 units).
Load Management The Freedom SW has a built-in
transfer relay that connects your inverter output or AC input
from the utility grid or generator to your loads. Because the
usual AC power sources such as campground outlets or small
generators often have limited current availability, having the
capability to manage your AC loads is extremely valuable.
The Freedom SW provides a number of features to facilitate
this:
• The charger is power factor corrected to use AC current
as efficiently as possible. Minimizing the AC current used
by the charger means more current is available for your
AC loads.
• Freedom SW has a power share feature which prioritizes
your AC loads by reducing the charge current in an
attempt to limit the total input current to less than the
breaker setting.
Occasionally, AC input sources have low voltage. To avoid
loading these weak sources any further, the charger
automatically reduces its AC current draw as the AC voltage
approaches the minimum acceptable level.
4 Freedom SW Owner’s Guide
Stacking
Introduction
Stack Charging
Supports stacking of two inverter/chargers to increase
capacity. This also requires the installer to select a Master and
Slave in order for the inverters to stack. Two configurations
of stacking are supported: Parallel stacking and Series
stacking.
Parallel Stacking Parallel stacking allows two inverter/
chargers to operate in parallel thereby doubling the capacity
in inverter mode. The two inverters communicate over the
network and intelligently share the load and to balance the
load between the two units. The Master Freedom SW
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.
Series Stacking Two units can be configured to generate
120/240 Split-phase power for load configurations that
require both 120 and 240 volts. In this configuration, the AC
source must be split-phase as well.
Two 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 passthrough (if two-stage charging is selected).
97-0019-01-01 5
Introduction
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 but the AGS is needed if a generator were to
be used in assisting the Freedom SW.
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 “Gen Support” on page 66.
Basic Protection Features
The Freedom SW has the following protection features:
• Over temperature shutdown for critical components such
as the transformer and the power board
• Battery temperature sensor (BTS) failure/battery
temperature out-of-range fault protection
• DC output over voltage protection during charge mode
• AC transfer relay failure detection
• AC output overload and short circuit protection during
invert mode
• AC backfeed
• Short circuit protection for the BTS and communication
connector ports including protection from incorrectly
inserting the remote panel communication cable plug into
the BTS port and vice versa
The Battery Temperature Sensor (BTS) provides these
protection features:
• Battery over temperature charging protection preventing
battery charging at 60 °C (140 °F) or higher
• Charging voltage compensation based on the temperature
of the battery where the BTS is connected
1
protection
1.An AC backfeed error occurs when the AC output of the inverter/charger is connected or routed back to the inverter/charger’s AC input terminal or if the internal
transfer relay fails.
6 Freedom SW Owner’s Guide
System Components
The Freedom SW uses Xanbus, a network communications
protocol developed to communicate the Freedom SW’s
settings and activity to other Xanbus-enabled devices.
You can configure and monitor the Freedom SW and every
Xanbus-enabled device in the system using an optional
Xanbus System Control Panel (SCP).
Another component is the optional Xanbus Automatic
Generator Start (AGS) which allows operation with a wide
range of generators, supported through a dedicated generator
input. Simply, the AGS automatically starts and stops your
generator.
The Freedom Sequence Intelligent Power Manager is a fully
integrated power management system that provides automatic
power and load management for use in recreational vehicles
(RV) while receiving power from a generator or shore power.
This device works in the background to prevent monitored
AC loads from exceeding shore and generator breaker
capacity.
See “Xanbus-enabled Products and Accessories” on page 9
for part numbers.
Xanbus System
The Xanbus system includes the Freedom SW and other
Xanbus-enabled devices. The Freedom SW is the device in a
Xanbus system that typically provides network power—500
mA at 12 volts DC. All of the Xanbus-enabled devices, such
as the Freedom SW, the SCP, and the AGS are able to
communicate their settings and activity to each other. See
