OutBack Power Vented Grid-Hybrid Inverter - 3500 Watts 24 Volts - UL 1741 SA Compliant

Manufacturer Part Number: VFXR3524A-01

FXR Renewable Series 120V A Model
Grid-Hybrid Renewable Energy System
UL 1741 SA, CA Rule 21, and HECO Rule 14H Compliant

The latest, most advanced features on the industry’s most trusted and proven platform—that’s the essence of OutBack’s 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.

Detailed Description

The new FXR features and technologies on the acclaimed FX platform include:

• 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

FXR inverter/chargers can be paired with a MATE3 to add OPTICS RE to monitor and control system performance from any location. Available in power ranges from 2000W-3600W, multiple units may be stacked and connected with other OutBack Power electronics for more seamless system integration and the ability to function in a wide variety of applications, and system sizes. Up to nine inverters can be combined in a 3-phase system with the 12V, 24V or 48V models, and up to 36kW in a grid-tied 24V or 48V system. The exclusive modular system architecture means that increased power output is just an additional FXR inverter/charger away.

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

The Future of Grid-Tie Stability

As more PV is installed on electrical grids, grid operators need flexible tools to help ensure stability and reliability. Areas with the highest PV penetration rates (Hawaii and California) will soon require grid interconnected systems to have "Grid Support" functions.

OutBack Power is certifying the Radian Series inverter/chargers (along with the FXR Series in the near future) under the new UL 1741 SA test standard to demonstrate compliance with these new requirements from CA Rule 21 and HECO Rule 14H.

What is UL 1741 SA and When Does it Take Effect?

UL 1741 SA is the new safety test standard certifying products which meet the rigorous requirements needed to ensure safe and reliable operation in support of grid modernization efforts. Grid support or "smart inverter" functionality will be required by Hawaii and California beginning September 8, 2017.

Although Hawaii and California are the first states to require grid support functions, expected updates to the IEEE 1547 interconnection standard will make these functions mandatory throughout most of North America within two to three years.

Is Grid Support Important?

As the PV market has grown, the industry has seen increasing grid instability, voltage rise limits, and a lack of standard communication protocol. With added grid support functions, the Radian Series inverter/chargers are being listed to UL 1741 SA, solving key grid integration challenges. UL 1741 SA compliance is planned for OutBack's FXR A Series in the near future.

With the advent of grid support technology, UL 1741 SA compliant models can regulate voltage and power, and they can prevent loss of power generation due to grid disturbances.
