OutBack Radian Series Inverter/Chargers

Both the 7048E and 3548E Radian inverters feature 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. Up to 10 units can be connected in parallel for systems up to 70kW continuous power output.


  • 3500 or 7000 VA continuous rating
  • Nominal Input Voltage:  48 (40 -64) VDC
  • Output Voltage: 230 Vac (+/- 9%)
  • Output Frequency: 50Hz or 60Hz (selectable) Sinewave
  • Power draw in on mode (idle): 34W
  • Max. Efficiency: 92%
  • Warranty: 5 years

Advanced Battery Charging (ABC) profile options to support battery technologies such as Lithium-Ion with enhanced diagnostics for improved performance.

Both units incorporate OutBack’s GridZero technology, a superior level of intelligence in energy management for self-generation and self-consumption programs to minimise grid dependance. This ensures renewable generated power is always used on-site when available with none exported to the grid and the grid only used to power load spikes when needed or if battery power is low. The battery is only ever carged from renewables (not the grid).
