OutBack Power Radian 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 and one for an optional backup generator. There?is a built-in 50 A transfer switch at 120/240 VAC. The output from this inverter is 120/240 VAC split?phase in each unit for easy tie-in to US standard wiring and grid connections.
The Radian features 4 kW (GS4048A-01) or 8 kW (GS8048A-01) of continuous output power and can?support large dynamic load variations and surge loads, making it well suited for demanding commercial?applications as well as residential use. With two power stages (one on the GS4048A-01), the modular?design is field serviceable. Radian inverters can be parallel stacked with up to ten inverters for 80 kW?total output.
The Radian inverters also have auxiliary controls that include a contact closure, a 12 VDC output signal,?and terminals for a remote on/off switch as well as a remote temperature sensor (RTS) for the battery?bank. Each GS8048A-01 inverter requires dual 2/0 AWG battery cables (two positive and two negative)?for connection to the battery bank. In fully off-grid applications, the minimum recommended battery size?is 175 Ah for the GS4048A-01 and 350 Ah for the GS8048A-01 for each inverter installed in a power?system.
The GS4048A-01 and GS8048A-01 inverters are made to work in off-grid, grid-tied, or grid-supported?systems using OutBack Power?s ?GridZero? mode, optimizing solar production where net metering is?not available. The ?A? inverters? have an adjustable input-voltage range so they can be made to?work with most lithium-ion, and other advanced battery technologies. The ?A-01??inverters are now listed to the new version of UL1741-SA so that they meet the new grid interactive?requirements of the utilities in some locations. Those locations currently include California and Hawaii,?and more states may be added over the next several years.
Each inverter comes with a standard 5-year warranty. The Radian is not rated for outdoor use. Dimensions are 28″H x 16″W x 8.7″D. Weight is 84 lbs for the GS4048A/GS3548E and 125 lbs for the GS8048/ GS8048A/GS7048E. Listed to UL 1741 for U.S.A. and Canada.
