SMA Central Inverters SUNNY CENTRAL 1600MV-20
 
For even more power per surface area: up to two high-performance Sunny Central HE-20 are part of a medium-voltage station (MV) that feeds directly into a shared medium-voltage transformer. This transforms two Sunny Central 800HE inverters, for example, into one Sunny Central 1600MV station. A peak efficiency of more than 98 percent is achieved using an amorphous transformer. The new MV station integrates highperformance communications components and also requires even less maintenance. Moreover, the new MV station offers extensive grid management functions and fulfills all of the requirements of the medium-voltage directive.
