Safety Information
ELECTRICAL SHOCK HAZARD
• Do not expose the Freedom SW 230V 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 two 12 V in series for a 24 V
battery bank) 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.

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. Restricted 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
NOTES:
1. Mount and place the Freedom SW 230V Inverter/Charger unit away
from batteries in a well ventilated compartment.
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.
PHYSICAL INJURY HAZARD
This Freedom SW 230V is not intended for use by persons (including
children) with reduced physical, sensory, or mental capabilities or lack of
experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play
with the appliance.
Failure to follow these instructions can result in minor or moderate injur
y
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.
• Always remove the negative terminal from the battery first for

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.
Precautions When Preparing to Charge
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.
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.
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 230V 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.

Introduction
Key Features
The Freedom SW 230V Inverter/Charger is a true sine wave
inverter/charger that can be used for mobile, marine and commercial
applications. The Freedom SW 230V 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 230V is a
convenient combination of an inverter, multistage 24-volt battery
charger, and transfer switch in one electronic device.
• As an inverter, the Freedom SW 230V 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 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 well pumps,
refrigerators, or A/C compressors.
• Power factor-corrected (PFC) input minimizes AC input
current required for charging, increasing AC pass-through
capacity.
• As a 24-volt charger, it has high output, multi-stage charging
capability minimizing charging time.
• Capable of operating from 50Hz and 60Hz power source by
extending AC qualification frequency range. See “ACIn
Settings” on page 56.
• Temperature-controlled, variable-speed internal cooling fans.
The fans turn on when the internal temperature reaches 55 °C
and reaches maximum speed at 70 °C. The fan turns off when
the internal temperature falls to 50 °C.
• Designed with efficient field serviceability in mind using
authorized service centers.
• The Freedom SW 230V Inverter/Charger is also Xanbus-
enabled which allows network compatibility and
communication with other Xanbus-enabled devices. See more
information under “System Components” on page 6.

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
230V has optimized algorithms for 24-volt 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 230V 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 230V’s multi-stage
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
230V includes is dead battery charging. The Freedom SW 230V—
unlike many chargers—has the ability to recharge batteries even if
the battery voltage is very low, i.e., as low as 12 volts.
Load Management The Freedom SW 230V 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 230V
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 230V has a power share feature which prioritizes
your AC loads by reducing the charge current and maintaining
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.

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.

Introduction
Basic Protection Features
The Freedom SW 230V 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 backfeed1protection
• 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 or higher
• charging voltage compensation based on the temperature of the
battery the BTS is connected to
1.An AC backfeed error occurs when the AC output of the inverter/charger is con-
nected or routed back to the inverter/charger’s AC input terminal or if the internal
transfer relay fails.

System Components
The Freedom SW 230V uses Xanbus, a network communications
protocol developed to communicate the Freedom SW 230V’s
settings and activity to other Xanbus-enabled devices.
NOTE: Xanbus is incompatible with other network communication
protocols such as TCP/IP found in many consumer electronic and
computer equipment.
You can configure and monitor the Freedom SW 230V 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.
See “Xanbus-enabled Products and Accessories” on page 7 for part
numbers.
Xanbus System
The Xanbus system includes the Freedom SW 230V and other
Xanbus-enabled devices. The Freedom SW 230V 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 230V, the SCP, and the AGS are able to communicate
their settings and activity to each other. See Figure 2.
