SMA SB 4.0-1AV-41 Three Phase Inverter

Higher yields for private homes - intelligent solar power generation

The new Sunny Boy 3.0–6.0 ensures maximum energy yields for private homes. This inverter combines the integrated Service SMA Smart Connected service and intelligent technology for all ambient requirements. Thanks to its extremely light design, the device can be installed quickly and easily. The Sunny Boy can be commissioned quickly via smartphone or tablet thanks to its integrated web interface. For specific requirements on the roof, SMA ShadeFix maximizes the PV system’s yield. Current communication standards make the inverter future-proof, meaning intelligent energy management solutions as well as SMA storage solutions can be flexibly added anytime.

Quick and easy to install

With its reduced weight, the Sunny Boy can be installed quickly while taking up minimal space. The Sunny Boy can be commissioned quickly via smartphone or tablet thanks to its web interface.

• One-person installation due to low weight of 17.5 kg
• Compact design through minimum space requirements
• Quick installation thanks to external connections
• Intuitive commissioning and local monitoring via a smartphone or tablet

Intelligent optimization of energy yield

Established product features and integrated software solutions will provide yield optimization throughout the system’s entire service life. Even in shading. SMA ShadeFix is a proprietary inverter software that optimizes energy yield in nearly every situation. SMA Smart Connected inverter monitoring offers enhanced safety by detecting errors at an early stage and automatically reporting them to the installer.

• SMA ShadeFix is an integrated software for yield optimization
• Dynamic active power limitation means direct use of excess energy and less power from the grid
• Automatic inverter monitoring via SMA Smart Connected
• System data visualization via Sunny Portal and Sunny Places
• Local visualization via Smart Inverter Screen

Flexibly expandable anytime

With the Sunny Boy, PV system operators can ensure that their PV system always generates maximum yields. If greater use of solar power is made in your own home, intelligent energy management and SMA storage solutions can be added at any time to systems with the Sunny Boy.

Effectively prevent electric arcs with SMA ArcFix

SMA ArcFix, the integrated arc-fault circuit interrupter (AFCI) in our inverters, is a highly effective tool for detecting possible electric arcs in the PV system. The inverter stops feed-in operation whenever an electric arc is detected. With the introduction of SMA ArcFix in our inverters, we continue to consistently raise the already high safety standard of PV systems.

Investment security included

With SMA Smart Connected, SMA offers free and automatic inverter monitoring that helps installers to provide customers with a quick, targeted service. If an inverter fails, SMA proactively informs the PV system owner and the installer. In this way, PV system owners and installers benefit from minimized diagnosis and downtime. If it is necessary to replace the inverter, SMA sends a replacement device fast and free of charge.
