New larger power classes of the Sunny Boy Smart Energy hybrid inverters: Questions are expected and we’ve got answers

With the launch of two new larger power classes of the Sunny Boy Smart Energy hybrid inverters, questions are expected and we’ve got answers. SMA America’s Marketing Program Manager Diana Lamadora sits down with Product Manager Alberto Landeros to go over the most frequently asked questions about the new Sunny Boy Smart Energy 9.6 and 11.5 kW inverters. He shares insights into the enhanced features, backup capabilities and technical attributes of the new 9.6 kW and 11.5 kW power classes, explaining why these inverters are a game changer for residential solar and storage.

DL: What technical attributes are different with the two larger power class Sunny Boy Smart Energy’s?

AL: What excites me most is the extra Maximum Power Point Tracking (MPPT) input—it gives installers more flexibility for complex rooftops while also delivering bigger backup power. The two larger power classes enable up to 5,700W of backup power when used with the upcoming SMA Backup Select, providing coverage for most essential home loads. This is a great feature for backup without the need for a battery.

DL: Why choose a higher power class inverter?

AL: Choosing a larger power class like the Sunny Boy Smart Energy 9.6 or 11.5 kW reduces the need for multiple smaller inverters. This simplifies system design, minimizes installation time and cuts equipment and labor costs, making the installation more efficient.

DL: What backup power options does SMA provide?

AL: The Sunny Boy Smart Energy offers two backup options, one available today and one available in the near future. SMA Backup Secure provides 1,920W of power through a dedicated 120V outlet, while the upcoming SMA Backup Select supports up to 5,700W and powers up to seven 120V loads during a grid outage. Both options offer homeowners flexibility without requiring a battery, just as long as the sun is shining.

DL: Why is portfolio expansion important?

AL: Expanding the Sunny Boy Smart Energy portfolio to include a wider range of power classes is essential for meeting the diverse needs of residential solar projects—whether aiming for full utility offset or supporting personalized sustainability goals. Smaller inverters may lack the capacity needed for certain projects, and using multiple smaller units can increase both complexity and cost. Larger power classes help reduce the number of system components and simplify installation, ultimately lowering costs while achieving overall sustainability goals. At SMA, our goal is to provide reliable solutions that meet diverse energy needs and requirements.

DL: Why choose Sunny Boy Smart Energy today?

AL: The Sunny Boy Smart Energy lets installers design smarter, install faster and deliver more value to their customers. With larger power classes, MPPTs, backup capabilities and trusted German engineering, it sets a new standard for flexibility and performance. Its hybrid design supports both PV and PV + storage, making it a versatile string inverter for today’s homeowners. Most recently, to better meet the needs of the market SMA adjusted the price of the Sunny Boy Smart Energy. The new pricing structure has allowed for lower overall pricing throughout the available power classes – giving customers one more reason to make the switch to SMA.

DL: Why is the Sunny Boy Smart Energy a smart choice for repowering existing PV systems?

AL: As a residential PV system ages, the overall efficiency declines. The Sunny Boy Smart Energy is a great choice for repowering these aging PV systems because of its easy installation, maximized energy yields, equipped with modern technology and offers modular expandability, making it a flexible solution that fits a variety of budgets. Soon, parallel MPPT support will add even more flexibility for complex array configurations.

Backed by over 40 years of industry expertise, SMA remains committed to delivering superior quality, proven reliability and a lasting commitment to a sustainable future. The Sunny Boy Smart Energy hybrid inverter sets itself apart with a higher range of power classes, up to four MPPTs and enhanced backup capabilities. Delivering unmatched flexibility in the market, with its simplified installation and commissioning, innovative technology and now competitive pricing, there has never been a better time to choose the Sunny Boy Smart Energy.
