The SMA Sunny Boy 4.0 Smart Energy is the ultimate hybrid inverter for do-it-yourselfers who want to maximise their solar power and take a smart approach to energy storage. This all-in-one solution combines both power generation and storage, so you get the most out of your solar panels and reduce your energy costs, even if the grid goes down. Perfect for future-ready homes where self-generated energy is key!

Key Features:

• Hybrid Technology: The Sunny Boy 4.0 combines an inverter and home battery in one device. This means you can store excess solar power instead of feeding it back into the grid. So you use your own energy at times when the sun is not shining.
• Three MPP trackers: maximum flexibility for your PV system. Even if your solar panels are on different roof sections or with different orientations, you will always get the most out of your set-up.
• Emergency power: Choose which essential devices you want to run during a power failure, so you are always powered up. Thanks to the built-in emergency power option, you won’t be left without power even in the dark.
• Smart Monitoring: With the SMA Energy App and Sunny Portal, you can easily monitor the performance of your system. Install the app on your smartphone and get real-time insight into your energy generation, storage and consumption, wherever you are.
• Maximum Power of 4000 W: With an input power of up to 8000 Wp, you can connect a large number of solar panels. Ideal for medium-sized households that want to be both self-sufficient and sustainable.

Benefits for the DIYer:

• Easy Installation: The Sunny Boy 4.0 is designed with user-friendliness in mind. Thanks to the SMA Easy Lock, you don’t need to be a professional to install this inverter. With a few simple steps, it hangs securely in place.
• Shadow management: Don’t worry about shadows on your panels. The built-in SMA ShadeFix technology ensures that your system performs at its best even in partial shade.
• Expandable System: Want to expand your system later with more panels or a larger battery? No problem! The Sunny Boy 4.0 is compatible with many battery brands and can be easily integrated into larger PV systems.

Tips & Tricks for a Successful Installation:

• Choose the right location: Make sure your inverter is hanging in a well-ventilated area to ensure optimal performance. Avoid direct sunlight or enclosed spaces without air circulation.
• Monitor your consumption: Built-in monitoring gives you insight into your consumption peaks. Plan the use of energy-intensive appliances (such as washing machines and dryers) when your solar panels are generating the most.
• Use the emergency power option smartly: Choose only the most crucial appliances to make optimal use of your battery capacity in case of a power failure.
