Range of Formats and Efficiencies to Meet Diverse Needs

The new and updated Sunny Boy range is setting new heights in residential inverter performance. Specially designed for countries that require UL listing, these inverters guarantee a safe installation process thanks to the automatic grid voltage detection.


With direct data exchange with Sunny Places and Sunny Portal

One of the greatest advantages of Webconnect is that data is transmitted directly from the inverter to Sunny Places and Sunny Portal – without the need for additional SMA devices.

  • With the add-on Webconnect functions, you only need an Internet connection and a DSL router.
  • Sunny Places and Sunny Portal provide a clear overview of the PV system data.
  • Compare PV systems and exchange ideas with other system operators on the Sunny Places.

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.

Thanks to innovative 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.

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.

  • The device is nearly silent.
  • Requires less service, saving time and money.

Modular design means easy expansion

When it comes to generating electricity with the micro inverter system, you can decide how small (or how large) your PV system will be (or become). Depending on the energy demand and your financial resources, the system can be expanded or varied step by step.

  • System size ranging from a single module (e.g., on a balcony) to a system offering several kilowatt-peak output.
  • Any number of additional micro inverters can be connected thanks to the flexible design of the Sunny Multigate (Depending on local regulations).

Less is more

When developing the Sunny Boy 240, SMA focused on the essentials. This means that we combined components, thereby doing away with entire assemblies. As a result, the device contains approx. 50 percent fewer components than competitor products.

  • Exceptional reliability and robustness thanks to just 16691 high-quality components.
  • Central functions outsourced to the Sunny Multigate (e.g., power line communication filter or grid disconnection device).


Exceptionally easy

Regardless of where and how the device is installed, electrical and mechanical planning work is reduced to a minimum. And installation and connection are extremely easy thanks to the ready-made, easily identifiable plugs.

  • Pre-assembled AC cables.
  • Choice of DC adapters.

Everything at a glance

Access to the Sunny Portal, which comes standard, allows the system to be monitored at a modular level. This means that PV system operators benefit from around-the-clock access to detailed analysis, diagnostic and yield monitoring functions.

  • Display of module and inverter data in real time.
  • Clear identification of shading/module problems.
  • Automatic reporting.


At home anywhere

A micro inverter system is also ideal for challenging applications with partial shading, a complex roof structure, small systems or different roof orientations.

  • In conjunction with an existing string inverter system or as a newly installed micro inverter system.
  • Greater yield with shaded or differently oriented modules.
