OutBack Power GS4048A-01 Radian Series 4kW Inverter/Charger, Grid-Interactive/Off-Grid, Listed to UL1741-SA.

The OutBack Power Radian Series GS4048A-01 Grid/Hybrid™ 4kW (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, it has 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. It also incorporates 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. GridZero technology make the new Radians ideal for use in complex utility environments such as California and Hawaii.

The GS8048A-01 are certified to UL1741 for US applications, and CSA C22.2 No. 107.1 for Canada, and is IEC 62109-1 certified to meet the most stringent worldwide PV safety and emission standards. This product is for selected North, Central and Latin American markets.

GridZero technology, found in OutBack’s Radian and FXR inverter/chargers, provides the perfect balance between utility power and stored renewable energy. By allowing a home or business to satisfy most of its power needs with renewable sources, grid supplied power is only tapped when load demand exceeds a pre-set threshold. While the inverter/charger is still grid-connected, grid dependence can be reduced to zero whenever possible. GridZero technology is ideal for use in complex utility environments where incentives are subject to change and utility sell-back options may be limited, such as California and Hawaii.

GridZero technology offers four critical advantages compared to typical systems:
