SMA Sunny Boy 3.0 Single-Phase 3 kW Solar Inverter

The SMA Sunny Boy 3.0 inverter, reference SB3.0-1AV-41, has been developed to maximize the performance of residential photovoltaic installations, offering a perfect balance between energy efficiency, advanced connectivity, and ease of use. With a nominal power of 3000 W, this device is designed for private homes that are committed to self-consumption and intelligent energy management.

Thanks to the integrated SMA ShadeFix technology, the Sunny Boy 3.0 optimizes production even under partial shading conditions, ensuring greater utilization of solar radiation. Additionally, its compact, lightweight, and transformerless design greatly facilitates installation, which can be completed in a few steps from a smartphone, tablet, or laptop via the integrated web interface.

It includes the SMA Smart Connected automatic monitoring service as standard, which monitors the inverter's operation in real-time and proactively notifies the installer and owner of any anomalies. This intelligent system improves preventive maintenance, reduces downtime, and allows for a quicker response in case of failure.
