About SMA Solar Technology AG

SMA Solar Technology AG develops, produces and sells solar inverters and monitoring systems for photovoltaic applications. SMA is the world’s largest producer in this segment and is the only vendor that has a product range with the matching inverter type for any module type and any power class. This applies for grid tied applications as well as island and backup operation.

The inverter is technologically the most important component in any solar power system: it converts the direct current generated in photovoltaic cells into alternating current suitable for the grid. In addition, it is an intelligent system manager, responsible for yield monitoring and grid management. Solar inverters are characterized by a particularly high efficiency. The Sunny Mini Central produced by SMA already has an efficiency of over 98 %, which allows for increased electricity production.

SMA’s business model is driven by technological progress. Due to its flexible and scalable production, SMA is in a position to quickly respond to customer demands and promptly implement product innovations. This allows the Company to easily keep pace with the dynamic market trends of the photovoltaic industry and at the same time absorb short-term fluctuations in demand for solar inverters.

SMA Solar Technology AG is headquartered in Niestetal, near Kassel, and is represented by sales and service subsidiaries on four continents in thirteen countries. This group of companies employs more than 5,500 employees (incl. temporary staff) and has been distinguished several times in previous years with awards for its outstanding performance as an employer. Since June 27, 2008, the Company has been listed in the Prime Standard of the Frankfurt Stock Exchange (S92), and since September 22, 2008, the Company’s shares have been listed in the TecDAX. In 2009, SMA generated an earnings before interest and taxes (EBIT) of more than € 228 million from a turnover of more than
€ 934 million. This corresponds to an EBIT margin of over 24 %.

It continuously collects all the data from the inverters on the system side, thereby keeping you informed of the system‘s status at any given time. The Sunny WebBox is a multi-functional, energy-efficient data logger which offers a wealth of options for displaying, archiving and processing data, even in networks with strict security regulations. In case of the event “Error”, the WebBox informs you immediately by e-mail or text message*. Even from remote locations where no DSL or telephone connection is available, measurement data can be transmitted to the Sunny Portal via a GSM modem.

Professional management, monitoring and presentation of PV systems

Whether for a small home system or a large solar park – central administration and monitoring of several PV plants saves time and money. Plant operators, installers and SMA service technicians have access to key data at any time, from any location. Pre-configured standard pages can be easily customized or supplemented with individually designed pages. Whether as a data table or as a highly configurable diagram: SMA solutions allow almost infinite options for analyzing measured data or visualizing yields. The yields of all inverters in a plant are compared fully automatically, permitting detection of even the smallest deviations. And the powerful reporting functions provide regular updates via E-mail to help insure yields.

The weather station for PV plants

The Sunny SensorBox is installed directly onto the modules and measures the sun radiation and temperature. In combination with Sunny WebBox and Sunny Portal, it provides a continuous target-actual comparison of plant performance. This makes it possible to detect shade, dirt, and gradually declining performance in a generator and thus maximizes yield security. Additional sensor for optional measurement of ambient temperature or wind speed permit more precise calculations.More info at
