Detailed Description

The OutBack Power Radian Series GS8048A-01 grid-interactive inverter adds new grid support functionality which can prevent loss of power generation due to grid disturbances with voltage and frequency ride through.

UL 1741 SA: Standard for Safety—inverters, converters, controller and interconnection systems equipment for use with distributed energy resources. Grid support or “smart inverter” functionality will be required by Hawaii and California beginning September 8, 2017. UL 1741 SA is the new safety standard certifying products which meet the rigorous requirements needed to ensure safe and reliable operation in support of grid modernization efforts.
