Outback Radian Series 8kW 48V Inverter/Charger 120/240V

The OutBack Radian Series 8kW Inverter/Charger (GS8048A) is a Grid/Hybrid powerhouse designed to make system design easy and versatile. Unlike many inverters that require two units to produce 240V, the Radian GS8048A produces native 120/240V split-phase power from a single unit. It serves as the central hub for both off-grid independence and grid-tied savings, featuring GridZero technology that prioritizes solar energy usage over utility power, even when connected to the grid.

Why Choose the Radian GS8048A

The GS8048A is the “universal” inverter. Whether you are living completely off the grid, retrofitting a backup system to an existing home, or selling power back to the utility, this inverter handles it all. Its defining feature is the Dual AC Input, which allows you to connect both the utility grid and a backup generator simultaneously. If the grid fails, the Radian switches to the generator automatically, ensuring your battery bank stays charged without manual intervention.

Benefits of the Radian Series

• True 120/240V Output: A single unit powers standard household lights (120V) and heavy appliances like well pumps, dryers, and A/C units (240V) without needing an external autotransformer.

• GridZero Technology: Perfect for areas with high utility rates or no “net metering.” This mode powers your loads with solar and battery energy first, only drawing from the grid when your demand exceeds the inverter’s capacity. It essentially allows you to “zero out” your grid usage as much as possible.

• Massive Surge Capacity: With a 5-second surge of 12 kVA, this inverter can start difficult loads like large well pumps and compressors that would trip lesser inverters.

• Future-Proof Compliance: The “A” series is UL 1741-SA listed, meeting the latest Rule 21 grid-interconnection standards required in states like California and Hawaii.

Frequently Asked Questions

Q1: Do I need two of these to get 240V?

No. A single GS8048A produces native 120/240V split-phase power. You can power your entire main breaker panel with just one unit.

Q2: Can I use Lithium batteries with this?

Yes. The Radian “A” series features Advanced Battery Charging (ABC) profiles specifically designed for Lithium-Ion battery chemistries, allowing you to customize charging voltages and termination currents precisely.

Q3: Does this work without batteries?

No. The Radian is a battery-based inverter. It requires a 48V battery bank to operate, even if you are using it primarily for grid-tie applications.

Q4: What is the difference between this and the GS8048 (non-A)?

The GS8048A is the newer version that supports Advanced Battery Charging (better for Lithium) and is UL 1741-SA compliant (required for grid-tie in many states). The older non-A model lacks these specific modern grid and battery features.

Q5: Can I connect a generator?

Yes. The unit has two AC inputs: one for the “Grid” and one for a “Generator.” It has a built-in transfer switch to toggle between them and can automatically start your generator (using a 2-wire start signal) when the batteries get low.
