The same. Only better. The universally usable Sunny Boy. It all remains the best: the new transformerless Sunny Boy is the ideal solution, especially for demanding PV arrays and partly shaded plants. Version 21 of the successful Sunny Boy offers a further array of advantages. It’s more flexible in its range of applications, provides even more efficient yields, and it’s easier to use. The high DC voltage of 750 V proves to be a cost advantage, since fewer parallel strings are required. In addition, the integrated grid management functions make the devices suitable for universal applications and allow them to actively support the grid.
