More efficient
Thanks to its 750 V DC input voltage.
Electrifying detail: Thanks to the higher, 750 volt maximum DC input voltage, often times one less module string is needed  because more modules can be switched on in a series.
• Highly flexible design reduces cabling requirements
• Maximum efficiency of 97 percent ensures top solar yield

More flexible
Thanks to multi-string technology
Greater flexibility in planning, implementing and solar harvest: The advantages of multi-string technology in the new transformerless Sunny Boy are also available in the 3 kW model.
• Optimal yield in partial shading and efficient operation of east/west arrays
• Two MPP trackers with expandable OptiTrac®* Global Peak operational control
• Optional: Single Tracker for complex or simple roof structures or as an add-on to existing PV plants

Easier
Thanks to innovativ mounting concept
The wall mount has also been redesigned, and now allows you to attach the inverter easily by inserting it from above.
• Fast and professional attachment, even on walls that are not completely straight
• Popular anti-theft protection option available

Universally applicable
Thanks to integrated grid management
Intelligent controls offer advantages in every situation: Thanks to its integrated grid management functions, the new Sunny Boy with Reactive Power Control offers universal deployment options and contributes to grid support.
• Fewer disconnections from the grid thanks to voltage reduction via reactive power
• Increased plant profitability

Multilingual
Thanks to international graphics characters
The user-friendly graphic display speaks a clear language: The dot matrix display can perfectly present any letter or symbol.
• Current display features Latin and Cyrillic letters as well as Japanese characters
• Upcoming software updates for additional languages such as Thai, Hebrew and Arabic

Low noise
Thanks to fanless operation
Sounds good: The new transformerless Sunny Boy works so efficiently that its cooling concept no longer requires the usual fan.
