Grid Support

  • 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.

  • 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.

  • 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.

  • The following inverter/chargers will have new models that are designed to be UL 1741 SA certified:

    • Radian A Series Inverter/Chargers (GS8048A and GS4048A) - including FLEXpower Radian integrated systems
    • FXR/VFXR A Series Inverter/Chargers (FXR2524A, FXR3048A, VFXR3524A, and VFXR3648A)

    OutBack has provided .GIP files and settings based on your location. This ensures your interconnected inverter settings are correct for your area, that's over 60 individual settings preconfigured for you! See the provided Excel Document for additional details.


    NOTE: A MATE3s is required to use .GIP files with your system.
