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.
