OutBack Power’s acclaimed Radian Series hybrid inverter/chargers can provide solar power and back-up power for almost any scenario. They are ideally suited for off-grid, on-grid, and grid interactive applications. 


The Radian GS8048A and GS4048A features dual AC inputs for grid/generator flexibility with no external switching required, unparalleled surge capability and operational stability, easy field upgrade-ability and stacking capability for large system scaling, simplified system commissioning through a powerful, easy to use configuration wizard and multi-mode operational flexibility.


These inverter/chargers incorporate OutBack Power’s GridZero technology: 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.


Monitoring & Control - Local and Remote

Radian Series inverter/chargers can be paired with a MATE3s to monitor and control system performance from anywhere in the world using Outback Power's free web-based portal OPTICS RE.
