SMA announces the availability of its Smartformer, a transformer and distribution box that is compatible with SMA's Sunny Island inverters. Available in the North American Market, the UL certified Smartformer facilitates easy application for off-grid or grid-tied battery backup single Sunny Island systems. With this product SMA continues its efforts to improve the performance of battery backup PV power systems.

"The step-up and step-down options that the Smartformer provides for single Sunny Island systems increases design flexibility for off-grid or grid-tied battery backup systems," said Jurgen Krehnke, president and general manager of SMA America and president of SMA Canada. "This solution is unique because it includes a bypass switch and a load shedding relay for battery discharge protection, which distinguishes the Smartformer from other autoformers by offering unmatched safety and versatility."
