SMA Sunny Boy Smart Energy Hybrid Inverter 4.8-US

The SMA Sunny Boy Smart Energy 4.8kW Hybrid Inverter is a next-generation solar-plus-storage inverter that gives you both flexibility and peace of mind in your solar power system. It acts as the central brain of your home’s energy system, allowing you to not only run on solar power during the day, but also to store excess energy for later use, including at night or during outages. With a combination of smart features, a compact design, and SMA’s reputation for quality, this inverter is ideal for homeowners who want a more reliable and flexible solar power system.

The SMA Sunny Boy brings together solar production, battery storage, and backup power capability in one streamlined unit. This smart energy 4.8kW hybrid inverter is designed to give you control over when and how you use your solar energy. It’s part of SMA’s latest generation of Smart Energy technology, and is built for simple installation, reliable operation, and intelligent energy management.

Unlike traditional grid-tied inverters, which shut down during power outages, the SMA Sunny Boy Smart Energy inverter provides the ability to add a backup outlet that keeps running during the day, even if the grid is down. You can also connect it to a battery bank to ensure you have continuous access to power when you need it most, including at night and during cloudy weather.

This inverter also includes a built-in SunSpec Rapid Shutdown transmitter, ensuring compliance with safety standards while helping reduce installation time. The unit’s compact, lightweight design makes it easier to handle and mount, even in smaller spaces. With SMA’s intuitive app, installers can scan, connect, and commission the inverter using a smartphone or tablet. Once installed, homeowners can monitor energy production and system performance through the same app, keeping everything clear and accessible.

The Sunny Boy Smart Energy 4.8kW Hybrid Inverter supports up to a 200% DC/AC ratio. This means you can connect more solar panels than the inverter’s rated AC output, allowing you to capture more energy throughout the day, especially during early morning and late-afternoon hours, boosting overall performance.

Three independent Maximum Power Point Tracking inputs give you flexibility when panels are installed on different roof faces or angles. Each input optimizes its own array to ensure the inverter captures as much energy as possible from every section of the system. The result is consistent, efficient operation even when sunlight varies across different panel groups.

SMA has a strong reputation for dependable, high-quality inverters, and this model continues that tradition. The SMA Sunny Boy comes with a standard 10-year warranty, with optional extensions up to 25 years. Its durable enclosure is built for outdoor use while maintaining a clean, unobtrusive design that blends into the home.

Key features and benefits of this smart energy 4.8kW hybrid inverter include the following:

This inverter is ideal for homeowners who want to take control of their energy use, reduce grid reliance, and prepare for future energy storage, even if a battery isn’t part of the initial install. Its hybrid design lets you begin with solar power alone and add batteries later without replacing the inverter.

For homes in areas prone to outages, the backup outlet provides a dependable safety net. During daylight outages, you can keep lights, electronics, or small appliances powered, avoiding the complete shutdown that traditional grid-tied systems experience. When paired with batteries, that protection extends to nighttime outages as well.

Whether you’re upgrading an existing solar setup or starting fresh, the SMA Sunny Boy Smart Energy Hybrid Inverter provides the foundation for a reliable and expandable system. With its smart integration, proven durability, and advanced energy control features, it helps you make the most of every ray of sunshine.
