Off-Grid
Solar. Wind. Hydro. Generator. No matter what your energy source OutBack’s products
are engineered to provide your home or business with reliable electricity day-in and dayout. e OutBack modular system architecture allows your system to grow along with
your power needs up to 36,000 watts. Power hungry appliances like washing machines, air
conditioning and power tools are easily started by our inverter’s substantial surge power
capability. When not being used, the inverter enters a power save mode, which consumes
as little as 3 watts, saving your battery power for when you need it the most. OutBack’s
innovative Maximum Power Point Tracking (MPPT) technology gets the most from your
solar array or can also control hydro or wind turbine charging sources. Complete system
status and control is easily monitored by a single control, instead of requiring the user to
keep an eye on multiple displays and status indicators.
Grid-Interactive
Grid-Interactive renewable energy systems enable you to demonstrate your personal
commitment to a renewable energy future. With the OutBack grid-interactive system,
backup AC power is made available 24 hours a day in the event of a utility outage, providing reliable power and peace-of-mind. At night, the inverter’s automatic power save mode
ensures that energy is not wasted by needlessly charging your batteries from the utility
grid. An average conversion efficiency of 91% using the California Energy Commission
(CEC) test protocol provides greater savings and a shorter time period for system payback.
OutBack’s grid-interactive technology provides you more than a typical solar inverter, we
also have an unmatched ability to utilize solar, wind and hydropower sources.
Mobile and Marine
OutBack’s Mobile and Marine inverter/charger models provide the high performance and
reliability you need no matter where your travels take you. Our die-cast metal construction
allows mounting in any position, even upside down. e required AC input neutral/ground
switching is taken care of by a fully integrated 30 amp AC transfer switch for shore chord
or generator hook-up. ree circuit boards and a simple design make field servicing the
unit easy no matter where you are. Rigorous testing at the factory ensures that each
inverter/charger works the first time as well as for many years to come.
European and Exports
Wherever you are in the world, OutBack’s European and Export off-grid inverter/chargers
are engineered to provide your home or business with reliable 50 Hz AC power. Our
high surge power capability starts the most demanding of 230 volt appliances and
the modular system architecture makes expanding a system’s power capacity or
switching to three-phase output power simple and trouble free. Both sealed (FX) and
vented (VFX) models are available with 50 Hz output to match your installation’s environmental conditions. e inverter/chargers low weight (as low as 27 kilograms) and
compact dimensions allow easy transport and installation in less than ideal locations.
Our field serviceable design eliminates the need to ship inverters if repair or upgrades
are required. Superior technical support is available from our European office, allowing questions to be promptly answered and any problems to be quickly resolved.

Sinewave Inverter/Charger
OutBack inverter/chargers are the next
generation in advanced power management. Each is a DC to AC
sinewave inverter, battery
charger and AC transfer
switch housed within
a tough die-cast
aluminum chassis.
Just like the local utility
grid, the inverter produces
true sinewave AC electricity for your stand-alone or
backup power needs. Computers, TVs and pumps are
just some of the examples of
modern electronics that last
longer and run better when
powered with true sinewave
electricity from an OutBack
inverter. Starting up your air
conditioning, washing machine or
well pump is worry-free because of
our high surge power capability.
improves performance in hot conditions.
FX
Sealed Inverter/Chargers
e FX series is designed to survive in
environments that would normally destroy
other inverter/chargers. Protection for
internal components is provided by our
die-cast aluminum chassis with a powder
coated fi nish to prevent corrosion. Internal
and external cooling fi ns allow for passive
heat transfer, enabling peak operating
effi ciencies as high as 93% and looking cool
while doing it. Water and small particles
are kept out through the generous use of
gaskets and 0-ring seals on all seams and
openings. A protective conformal coating
on all circuit boards provides the fi nal line of
defense against corrosion. e now standard
externally mounted “TURBO” cooling system
Batteries and generators are the costly
consumables when using inverters
to generate electricity. e integrated
smart battery charger uses multiple
stages to perform quick recharging
while prolonging battery life, saving
your batteries and generator from
unnecessary wear. Automatic switching
between AC power sources is seamless
due to an AC transfer switch that reacts
in less than 16 milliseconds.
Unique networked communication
is built into all OutBack products providing complete integration. Expanding
your system with your growing power
needs is as simple as adding additional
inverters with modular architecture.
Further fl exibility is provided with the
ability to be connected at any time in either parallel, series or three-phase power
confi gurations. Industry leading OutBack
reliability is achieved through simplifi ed
design and rugged construction.
