SMA from its headquarters in Kassel, Germany, is the world’s largest producer of solar inverters and monitoring systems for photovoltaic applications.  As market leader for solar inverters SMA is setting benchmarks again and again: leading-edge efficiencies of 98% and new technology ensures maximum yields and the highest user convenience.

SMA offer a wide range of solar photovoltaic inverters including the SunnyBoy range starting at 1.2kW for small domestic applications through the larger Sunny Mini Central range for small commercial to the 100kWSunny Central products for industial scale applications.

The range includes newly developed lighter and more efficient “high frequency” transformed products (-HF) along with transformless products (-TL).

All inverters support a range of optional display and monitoring accessories for visualisation of the system operation and many models have Bluetooth bulit-in as standard enabling fast integration with these additional products.

The innovative design of the Sunny Boy 1.5/2.5 is not only easy to install, but also allows for quick DC and AC connections. Because it weighs just 9 kg, it can be suspended from just two screws, with no additional wall mounting bracket. Commissioning is equally easy, because the integrated user interface (Web UI) makes it possible to choose the necessary settings in next to no time – without opening the cover.

With its focus on what really matters, the Sunny Boy 1.5/2.5 also offers impressive communication features. The intuitive user interface (Web UI) makes it possible to monitor system data on any smartphone, tablet, laptop or traditional PC. This enables the user to choose between local and online monitoring via Sunny Places and Sunny Portal.
