The latest, most advanced features on the industrys most trusted and proven platformthats the essence of OutBacks new FXR Series of Grid/Hybrid inverter/chargers. Capable of off-grid or grid-connected operation in a single model, the FXR Grid/Hybrid inverter/chargers provide system designers with unprecedented flexibility and compatibility for nearly any power conversion scenario.
The new FXR features and technologies on the acclaimed FX platform include:
Both off-grid and grid-tied functionality in one unit
- Seven programmable modes, including GridZero and Support Mode and built-in networked communications
- Advanced Battery Charging (ABC) with expanded charging voltages and time parameters, enabling system designers to accommodate the specific charging profiles and algorithms of new and emerging energy storage technologies including Lithium Ion, Aqueous Ion and Flow chemistry batteries
- Easy system upgradability in the field
Available in sealed or vented units with NEMA type 1 die-cast aluminum chassis designed to operate in the harshest environmental conditions such as high temperatures, humidity or corrosive salt air, the FXRs continue in OutBacks tradition of absolute dependability in mission critical installations no matter how harsh or challenging the conditions.

Radian Series
Full-Flexibility, Grid-Interactive/Off-Grid
- Product Highlights
- NEW Frequency shifting AC coupling
- Grid-interactive and stand-alone capability in the same package
- Unsurpassed surge capacity
- Dual AC inputs
- Field serviceable modular design
- GSLC load center option allows for quick and easy installation
The Radian Series Grid/Hybrid (full-flexibility grid-interactive/off-grid) Inverter/Charger is engineered toward one goal: making system design and installation easier and faster in grid-interactive and comprehensive off-grid applications. The new Radian Series inherit the hallmark features of the original design, including: dual AC inputs for grid/generator flexibility with no external switching required, unparalleled surge capability and operational stability, easy field upgradeability and stacking capability for large system scaling, simplified system commissioning through a powerful, easy-to-use configuration wizard, and multi-mode operational flexibility.
In addition, both models have a new Advanced Battery Charging (ABC) profile option to support leading-edge battery technologies such as Lithium-Ion and others, and enhanced diagnostics for improved performance. And both incorporate OutBacks GridZero technology, a superior level of intelligence in energy management for self-generation and self-consumption programs, providing precise balancing between using stored energy, solar and utility power, blending-in the latter to overcome surges and load spikes when needed. GridZero operation makes it possible for a smaller inverter and battery system to perform like a much larger one when required, putting stored and renewable energy sources to work and minimizing grid dependence. GridZero technology make the new Radians ideal for use in complex utility environments such as California and Hawaii.
The GS8048A and GS4048A are certified to UL1741 for US applications, and CSA C22.2 No. 107.1 for Canada, and is IEC 62109-1 certified to meet the most stringent worldwide PV safety and emission standards.
The GS7048E and GS3548E are IEC certified to meet the most stringent worldwide PV safety and emission standards.

Radian Series GS Load Centers
GS Load Centers
- Product Highlights
- Pre-wired or customized options for quick and easy installation
- Dual AC inputs and DC connections
- 120/240VAC and 230VAC designs
- UL 1741 end-to-end
- Greater dynamic stability
- Dual AC inputs
- Fully integrated from industry leading brand
OutBack Powers GS Load Centers are an integrated connection enclosure series for AC and DC system connections in OutBack Radian Series inverter/charger applications, through provided inverter DC overcurrent protection and disconnects, dual AC inputs, grid-tie inverter connection and 120/240VAC or 230V maintenance bypass.
Designed for use with the Radian Series inverter/charger family, the options offer solutions for ground-up custom designs or factory pre-wired configurations for specific applications.
The OutBack GS Load Centers simplify the configuration, distribution, and implementation of energy storage of the Radian Series inverter/charger through a standardized approach.
NOTICE: The new 300V GS load centers accommodate FLEXmax 100 charge controllers. Due to the different voltage ratings, OutBack Power does not recommend mixing the FM100-300VDC with the FM60 or FM80-150VDC controllers on the same battery bank. Be sure to review installation instructions when installing OutBack Power equipment.

M-Series
Full-Flexibility, Grid-Interactive/Off-Grid
- Product Highlights
- True sine wave output
- Intelligent battery charging
- Modular, stackable design
- Weather-resistant sealed chassis
- Corrosion-resistant internal components
- Standard 5-year warranty
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. The 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.
Three 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.

OBX Extreme Series
Off-Grid Inverter/Charger
- Product Highlights
- Pure sine wave power output
- Water-resistant sealed chassis
- Flexible mounting design
- Intelligent battery charging
- Integrated AC transfer relay
The OutBack Extreme Series Inverter/Charger is all that its name implies. Built from exceptionally rugged components not available in regular commercial off-the-shelf" inverter/chargers, the water-resistant Extreme Series Inverters are designed to survive harsh environmental conditions including shock and vibration.
The Extreme Series Inverter/Charger features intelligent battery charging and an integrated AC transfer relay with automatic neutral-ground switching for mobile applications. A mount anywhere design and silent operation, along with low-distortion pure sine wave power output, make them ideal for mobile electrical needs, and their ample surge capability can start multiple heavy loads simultaneously. Integrated building block architecture allows expanding a system from 2 to 36 kW, and user-defined settings allow systems operation at 120 VAC, 120/240 VAC or 120Y208 VAC three-phase by stacking multiple Extreme inverter/chargers together.
