OutBack Expands Radian Family to Extend Value for Customers across Global Markets

OutBack Power Technologies, Inc. announced the grid-interactive Radian Series GS4048A and the GS3548E Inverter/Chargers, which give installers the ability to suit residential, industrial and commercial off-grid and grid connected applications throughout the world. Expanding the range of the GS8048 and GS7048E 8kW and 7kW Radian Series family, the 4kW and 3.5kW inverters deliver power, value and flexibility to installers, and enable end users to reduce costs and increase reliability through grid-interactive renewable energy systems. The newest Radian sizes address installer needs to suit varying voltage standards and electrical load requirements in emerging countries, and provide advanced grid management options for those regions which may not support full grid-interactive operation.

OutBack Power’s grid-interactive technologies offset utility costs when the grid is up and deliver reliable power when utilities are down. The Radian Series GS4048A and GS3548E give distributors the ability to stock two inverter/charger models and give installers the ability to power grid-interactive and off-grid systems in North, South and Central America, as well as in the Caribbean and in Japan. Installers choose the appropriate voltage, frequency and grid interface protection parameters for the particular market, and then use OutBack Power’s configuration wizard to program the devices accordingly. Both models support ac coupling through a compatible OutBack Power load center to provide an economical solution for upgrading or retrofitting existing grid-tied systems for battery backup capability.

“OutBack Power’s latest Radian models build on the tradition of our powerful, flexible inverter/chargers to bring grid independence and energy storage to more installations worldwide,” said Phil Undercuffler, director of product management and strategy for OutBack Power. “With the latest additions to the Radian family, OutBack Power makes it easier than ever for installers to support customers across international borders.”

The Radian Series' GS4048A and GS3548E dual ac inputs enable customers to sell power back to the local utility from one input with easy, coordinated integration of a generator for backup charging. In this way, users get both the payback of net metering where it’s available and the assurance of near-infinite run time in the event of a natural disaster. The Radians also offer advanced battery support, so installers working with lithium-ion, flow batteries and other new and emerging technologies, as well as traditional lead acid batteries, can optimize systems to leverage their specific energy storage capabilities.

Other key features of the GS4048A and GS3548E Radian Inverter/Chargers include: Field-adjustable input/output voltage and frequency boundaries of 50/60Hz, 200-260V and 210-250V nominal, respectively; Field serviceable modular design and upgradeable firmware; Unsurpassed surge capacity; Dual ac inputs; UL1741 certified for U.S. applications; IEC 62109-1 certified to meet global PV safety and other certifications to meet international emission standards; OutBack Power’s 4048A and 3548E Radians will be available in Q1 2014.
