The Radian GS4088A and GS8048A are designed to work in off-grid, grid-tied or grid-supported systems using OutBack’s GridZero mode, which optimizes solar production where net metering is not available. These A series inverters also have an adjustable input voltage range to enable them to be used with Li-ION and other battery systems.

The Radian Series GS8048A and GS4048A Grid/Hybrid™ (full-flexibility grid-interactive/off-grid) Inverter/Charger is engineered toward one goal: making system design and installation easier and faster in grid-interactive and comprehensive off-grid applications. The new Radian Series inherit the hallmark features of the original design, including: 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 the GS4048A and the GS8048A Outback models have a new Advanced Battery Charging (ABC) profile option 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 systems to perform like a much larger one when required, putting stored and renewable energy sources to work and minimizing grid dependence. GridZero technology make the new Radian A series ideal for use in complex utility environments such as California and Hawaii.

An OutBack MATE3, HUB4 or HUB10 and an appropriate GSLC (GS Load Center) are needed to complete a Radian system.
