SMA Makes PV System Design a Snap with Next-Generation Configuration Software

Sunny Design 2.0 Offers New Functions, Redesigned User Interface

ROCKLIN, Calif. and TORONTO, June 2, 2011—SMA has released its next-generation photovoltaic system design software: Sunny Design 2.0. Available for free download at, Sunny Design 2.0 offers a variety of new features and a user-friendly interface that make PV array planning even easier.

SMA's Sunny Design helps solar installers and system planners visualize possible PV plant designs and select the optimum configuration quickly and easily. Based on module selection and other basic system parameters, Sunny Design suggests inverter models and string sizing that accommodate the desired system size. Complex plants with several different sub-arrays and inverter types can be combined into a single project.

"A successful PV project begins with optimal system configuration," said Jurgen Krehnke, president and general manager of SMA America and president of SMA Canada. "The innovative Sunny Design 2.0 software saves solar installers and system planners valuable time while providing critical design data that helps them create a tailor-made solution for their customers."

New features of Sunny Design 2.0 include an enhanced user interface; inverter selections based on grid-connection voltage; improved visualization of system performance characteristics; and the ability to export user-defined modules and locations for exchange with other users.

Also included are the traditional capabilities of the Sunny Design software, such as an extensive database of available PV modules; worldwide location support with high-resolution meteorological data; cable dimensioning assistance; and annual projected energy estimates. Users can also create reports with key project values and then print or save them as a PDF document.

US Battery - Solar RE L16XC Renewable Energy Battery

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
