Full flexibility and great features
The GS4048A inverter/charger can be used with grid-interactive or off-grid systems. This series (GS4048A and GS8048A) of Radians include all the same great features of the original Radians—dual AC inputs, surge suppression, ease of installation and stacking capability—plus great new features.

GridZero technology and Advanced Battery Charging
Outback Power has included GridZero technology which uses the grid at key moments to keep your loads online without cycling your battery bank. By keeping a small stream of grid power channeled to your battery bank you don't sacrifice its longevity. Advanced Battery Charging expands charging voltages, helping to accommodate leading-edge battery technologies such as Lithium-Ion and others.

About Outback Power

Founded in 2001 by three engineers with a long history of developing technologies for renewable energy applications, OutBack’s founders believed that the renewable energy industry was on the verge of unparalleled growth, driven by the emerging need for sustainable alternative sources of energy.

OutBack initially designed and manufactured integration hardware used by solar installers to house and protect power electronics installed in remote environments and harsh condition locations around the world. Soon the company launched an advanced line of rugged inverter products that delivered pure sinewave power for off-grid residential and commercial installations, ultimately expanding its offering to include off-grid inverters with battery backup, grid-tie inverters with battery backup, Maximum Power Point Tracking (MPPT) charge controllers, communications products and a complete line of OutBack EnergyCell batteries designed specifically for renewable energy applications. Over that time, they forged a reputation as the recognized leader in the design and manufacture of battery-based, off-grid renewable energy systems.

17 years later, they continue to lead the way with advanced off-grid and grid-interactive battery-based renewable energy systems, the fully UL 1741 SA listed Radian Series and FXR Series inverter/chargers and their SystemEdge packages that bundle the right combination of energy storage and power electronics, merging energy independence with smart home technology for a range of common applications.

OutBack is also a member of The Alpha Group -- a global alliance of independent companies that share a common philosophy of creating world-class powering solutions for the renewable energy, communication, commercial and industrial markets. Bottom line: If you are installing or upgrading to a battery-based renewable energy system, the Solar + Energy Storage Experts at OutBack Power are the only choice.
