Outback Inverters

Outback Inverters

The OutBack modular system architecture allows your system to grow along with your power needs up to 36,000 watts on the FXR inverters and up to 80,000 watts with the Radian Inverters . 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.

NEW Outback VFXR and FXR Hybrid Inverter 

Note: If you are replacing an FX inverter in an existing multi inverter system you must use the old FX models. The VFXR and FXR models are just for use in new systems.

The OutBack FXR series inverters are a more advanced version of the venerable FX series. These new inverters are a good choice for off-grid or, with the 24 VDC and 48 VDC inverters, can be used in a grid-tied system. They have expanded voltage ranges for use with advanced-technology batteries, and have the advanced OutBack features including Grid Zero and Offset modes.

The ventilated OutBack VFXR inverters offer more power in high ambient-temperature applications, and more throughput for generator-powered battery charging. The sealed, externally fan-cooled FXR is designed to be used in coastal or dusty environments.

Each inverter/charger is a multi-mode power conversion unit that includes an inverter, battery charger, and an AC transfer switch. Up to ten inverters can be stacked in parallel (120 VAC), up to eight inverters can be stacked in a series configuration (120/240 VAC), and up to nine inverters can be stacked for threephase (120Y208 VAC) configurations. The 50 Hz export inverters can be stacked up to ten in parallel (230 VAC), and up to nine inverters in a three-phase configuration (230Y400 VAC). When stacking, all of the inverters must be the same model. The X-240 and similar transformers are not used with the FXR inverters. Due to the added control features, FXR series inverters should be deployed with the MATE3 controller (or AXS Port) and the Hub10.3; older models may not function properly. These inverters, with the MATE3 or AXS port, are compatible with OutBack OpticsRE.

VFXR inverters have a programmable, auxiliary relay output connection (AUX) that provides 12 VDC output to run cooling or ventilation fans or to operate an external relay for other functions, such as remote generator starting (two-wire). Sealed FXR inverters use this relay to power the external cooling fan, so it is not available for other uses.

The internal transfer switch is rated for 60 A. When an external source of AC power (either a generator or the utility grid) is detected at the “AC in” terminal on the inverter, the switch operates to transfer the loads to the external power source, and then activates the battery charger to recharge the battery bank depending on what mode is programmed. Use the FlexWare 250, 500, or 1000 components with these inverters or refer to the pre-wired FLEXpower systems featuring FXR series inverters. Dimensions: 16.25"L x 8.25"W x 11.5"H. Listed to UL 1741 (2nd edition) and CSA 22.2 by ETL for the U.S.A. and Canada and covered by a five-year warranty.

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 OutBack’s tradition of absolute dependability in mission critical installations no matter how harsh or challenging the conditions.

Outback Radian Grid Hybrid Inverters.

OutBack Radian inverters work equally well as a grid-tie or off-grid inverter. There are two separate AC inputs, one for the bi-directional grid connection and one for a backup generator. There is a built-in 50 A transfer switch at 120/240 VAC. The output is 120/240 VAC split phase in each unit for easy tie-in to US standard wiring and grid connections. The Radian features 4 kW (GS4048A) or 8 kW (GS8048A) of continuous output power and can support large dynamic load variations and surge loads, making it well suited for demanding commercial applications as well as residential use. With two power stages (one on the GS4048A), it is able to provide high efficiency and redundancy for critical applications, and the modular design is field serviceable. The Radian can be parallel stacked with up to ten inverters for 80 kW total output. The Radian also has auxiliary controls that include a contact closure, a 12 VDC output signal, and terminals for a remote on/off switch as well as a remote temperature sensor (RTS) for the battery bank. Each GS8048A inverter requires dual 2/0 AWG battery cables (two positive and two negative) for connection to the battery bank. In fully off-grid applications, the minimum recommended battery size is 175 Ah for the GS4048A and 350 Ah for the GS8048A for each inverter installed in a power system (See Batteries Section).

The GS4048A and GS8048A inverters are made to work in off-grid, grid-tied, or grid-supported systems using OutBack’s “GridZero” mode, optimizing solar production where net metering is not available. The “A” inverters also have an adjustable input-voltage range so they can be made to work with most lithium-ion, aqueous sodium-ion and other advanced battery technologies.
