SMA America Inc. (Grass Valley, CA) announced a UL1741 listing for its Sunny Central 125 kW Utility Interactive Inverter. The SC125U is the latest addition to the SMA family of renewable energy products. It is the culmination of many years of experience with the SMA Sunny Boy and European Sunny Central photovoltaic inverters.
The design incorporates the same MPP tracker found in more than 200,000 fielded Sunny Boy inverters. The ac isolation transformer is incorporated within the inverter cabinet and is disconnected whenever the inverter is not producing power. This eliminates the unnecessary and costly power losses found in other central photovoltaic inverters.
