SMA Inverter 4kW Sunny Boy 4.0 SINGLE-PHASE
€1.378,28 IVA esc.
The SMA Sunny Boy 4kW SB4.0-1AV-41 inverter is an innovative SMA solution for installations with single-phase grid connection without battery, with an output power of 4000W.
The new Sunny Boy 4.0 guarantees maximum energy yields for private homes. The inverter combines the SMA Smart Connected service with intelligent technology to meet all environmental requirements. The system can be easily installed thanks to its extremely lightweight structure. The integrated web interface allows for quick commissioning of the Sunny Boy via smartphone or tablet. For specific roof requirements, SMA ShadeFix maximizes the photovoltaic system’s yield. Thanks to cutting-edge communication standards, the inverter can be integrated with intelligent energy management solutions and future-oriented SMA storage solutions with maximum flexibility, even at a later stage.
Basic system functions
- Easy commissioning thanks to integrated WLAN and Speedwire interfaces
- Maximum transparency through visualization on Sunny Portal / SMA Energy App
- Investment security thanks to SMA
- Smart Connected
- Modbus as interface with third-party solutions
Extended system functions
- Basic system functions
- Reduced grid consumption and increased self-consumption through the use of stored solar energy
- Maximum energy utilization through forecast-based charging
- Increased self-consumption through intelligent load control
- Easy integration of ripple control receiver via SMA Power Limiter
- With SMA Energy Meter, maximum system utilization thanks to dynamic grid feed-in limitation from 0% to 100%
- With SMA Home Manager 2.0, maximum integration with devices such as Vaillant heat pumps
- Energy consumption visualization
In addition to features like SMA ShadeFix and SMA Smart Connected, integrated TS4-R communication for module optimization is now added. Shade is therefore no longer a problem. In case of light shading, the integrated SMA ShadeFix management system ensures maximum yield. For more pronounced shading or complex roof structures, TS4-R optimizers, installed only where needed, guarantee high yields.
NEW:
- Integrated TS4-R communication for module-level monitoring
- Integrated shade management through built-in SMA ShadeFix
- Dynamic active power limitation: direct utilization of excess energy, reduced grid consumption
- Automatic device monitoring through SMA Smart Connected
- Free online monitoring via Sunny Portal and Sunny Places
