Individual performance at an industrial level: in combination with an external transformer, the Sunny Central 500HE-US can be connected to any imaginable power distribution 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 power class. SMA also supplies complete megawatt skids with two inverters and external AC/DC disconnectors located centrally in a Disconnect Unit and a transformer.
