Detect problems at an early stage, optimize yields and reduce maintenance costs - intelligent generator junction boxes (GAKs) are evolving from simple protection devices to the digital control center of modern PV systems. A development that is fundamentally changing the monitoring of solar parks.
Sizing of Generator Junction Boxes
When planning large-scale PV systems, the correct dimensioning of generator junction boxes (GAK) is a key decision. While standard solutions are sufficient for many applications, complex projects often require customized configurations. The trick is to recognize when which approach is the right one.
