Radian

 Series

GS7048E & GS3548E Inverter/Chargers

OutBack Power’s acclaimed Radian Series made the benefits of 

Grid/Hybrid technology available and accessible in one agile 

powerful, platform ideal for nearly all off-grid or grid-connected 

system architectures. 

The Radian Series GS7048E and all-new GS3548E features dual AC 

inputs for grid/generator flexibility with no external switching required, 

unparalleled surge capability and operational stability, easy field 

upgradeability and stacking capability for large system scaling, simplified 

system commissioning through a powerful, easy-to-use configuration 

wizard, and multi-mode operational flexibility. 
In addition, both models have new Advanced Battery Charging (ABC) 

profile options to support leading-edge battery technologies such 

as Lithium-Ion and others, and enhanced diagnostics for improved 

performance. And both incorporate OutBack’s GridZero technology, a 

superior level of intelligence in energy management for self-generation 

and self-consumption programs, providing precise balancing between 

using stored energy, solar and utility power, blending-in the latter to 

overcome surges and load spikes when needed. GridZero operation 

makes it possible for a smaller inverter and battery system to perform 

like a much larger one when required, putting stored and renewable 

energy sources to work and minimizing grid dependence.

As truly global products, the Radian Series GS7048E and GS3548E 

inverter/chargers offer selectable voltage and frequency for use in 

a wide variety of locations, and innovative grid interface protection, 

which allows precision programming and control to accommodate 

shifting utility requirements in areas with high PV penetration or specific 

interconnection requirements. Complete system interfacing using the 

OutBack MATE3 and HUB communications manager enables the Radian 

Series to be connected with other OutBack Power electronics providing 

industry leading integration and a scalable power solution. Up to 10 

units can be connected in parallel for systems up to 70kW continuous 

power output. 
The GS7048E and GS3548E are IEC certified to meet the most stringent 

worldwide PV safety and emission standards.
This product is for Europe, Asia and other global markets.
