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.
