OutBack Radian GS8048A inverter work equally well as a grid-tie or off-grid inverter. The Radian Series GS8048A Grid/Hybrid™ with GSLC175-PV-120/240 Prewired Load Center (full-flexibility grid-interactive/off-grid) inverter/charger that is engineered toward one goal: making system design and installation easier and faster in grid-interactive and comprehensive off-grid applications. The GSLC175-PV-120/240 Prewired Load Center simplifies the configuration, distribution, and implementation of energy storage through a standardized approach with the Outback Radian inverter, making it easier than ever to provide successful solutions for virtually any residential, commercial power requirement. Radian Series GS8048A system is designed for a quick installation. Choose either roof, ground or pole mount rack which will save you both time and money. As with all Blue Pacific Solar's kits, our Technical Sales staff is standing by to provide support that is as close as your telephone.

OutBack Radian GS8048A inverters work equally well as a grid-tie or off-grid inverter. There are two separate AC inputs, one for the bi-directional grid connection and one for a backup generator. There is a built-in 50 A transfer switch at 120/240 VAC. The output is 120/240 VAC split phase in each unit for easy tie-in to US standard wiring and grid connections. The a single Radian features 8 kW of continuous output power and can support large dynamic load variations and surge loads, making it well suited for demanding residential applications. The GS4048A support a wider range of battery charging parameters and are recommended when using advanced battery chemistries, such as lithium ion. These two inverterspre-engineered also include OutBack's new Grid Zero feature, which enables them to manage input from the utility grid in parallel with the inverter output, and are recommended for systems that aren't net metered. With two power stages, the GS8048A are able to provide high efficiency and redundancy for critical applications, and the modular design is field serviceable. The Radian series inverters can be parallel stacked with up to 10 inverters for 80 kW total output. The GS8048A can also be stacked for a 12 kW system. In fully off-grid applications, the minimum recommended battery size is 350 Ah for the GS8048A for each inverter installed in a power system.

The GS Load Center (GSLC175-PV-120/240) is a wiring and circuit protection enclosure that mounts under the Radian inverter. The GS Load Center includes positive and negative main inverter busbars, a 500 A 50 mV shunt with negative terminal bar, the main DC positive breaker plate, ground and neutral terminal bars, and 2 PV positive terminal bars. Up to two charge controllers can mount on the right side, and the HUB10 can mount on the left side. The GSLC175-PV-120/240 includes the 175-120/240 unit plus two 80 A PV array breakers, a two pole GFDI 80 A breaker, three 500. A 50 mV shunts with shunt bus, and a FLEXnetDC. The GFDI acts as the breaker between the control and positive bus; there are no other breakers added for this purpose.

The GS8048A is certified to UL1741 for USA applications, and is IEC 62109-1 certified to meet the most stringent worldwide solar safety and emission standards.

Outback 2700W Radian GS8048A Kit Grid-Interactive / Off-Grid Renewable Energy System

Outback 2700W Radian GS8048A Kit featuring the 120/240V 60Hz Outback Radian is an 8,000 to 16,000 Watt continuous power solution that seamlessly integrates with traditional North American wiring practices. The models combine pure sine wave power output technology with unsurpassed surge capability to start the most demanding appliances, and are built around a unique dual-power module design which ensures high efficiency in both low and full power operation as well as redundancy in mission-critical applications.

The GS8048A 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. 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 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.

GS8048AIMPORTANT SAFETY INSTRUCTIONS: It is the responsibility of the purchaser to ensure that all products are installed and operated in accordance with local and national building codes as specific by the NEC (National Electric Code), UBC (Uniform Building Code) or IBC (International Building Code) and local utility company policy. This product is designed for indoor or protected compartment installations. DO NOT expose the inverter to rain, snow, moisture or liquids of any type. Use insulated tools to reduce the chance of electrical shock or accidental short circuits. Remove all jewelry such as rings, watches, bracelets, etc. when installing the Outback inverter or any other electronic gear. Always disconnect the batteries or energy source prior to installation or performing maintenance on the Outback, GS8048A inverter. Live power may be present at more than one point since an inverter utilizes both batteries and AC electricity. Turning off the inverter may not reduce that risk. Always verify proper wiring prior to starting the inverter. Do not operate the inverter if it has been damaged. Always read and follow the manufactures installation and operating instructions for the Outback 2700W Radian GS8048A Kit prior to installation and operation.
