SUNNY CENTRAL- High Tech for solar power stations
We have developed the Sunny Centrals specially for use in large PV power stations and open-field plants. Hence they possess completely special properties. String monitoring, capacity for teamwork and the ability to feed into the medium-voltage power grid make them first choice for PV systems with homogenous structure.
Sunny Central 500HE-US
The ideal solution for PV power stations in North America
Individual performance at an industrial level: In combination with an external transformer, the Sunny Central 500HE-US can be connected with any imaginable grid, which it also actively supports with the new grid management function. The outdoor enclosure with OptiCool cooling concept and the separate connection area ensure simple installation and low system costs. With its peak efficiency of 98.6 %, it outdoes all other devices in its performance class. SMA also supplies complete megawatt skids with two inverters and external AC/DC disconnectors located centrally in a Disconnect Unit and a transformer.
