The Siemens Industry Automation Division has expanded their portfolio of central inverters with the system boxes Sinvert PVS ControlBox 300, Sinvert PVS ComBox 100 and ComBox 200 as well as the Sinvert PVS WeatherStation 200. The system boxes are designed as an accessory component for the new Siemens inverters of the Sinvert PVS800 series as well as for the Sinvert PVS500 and Sinvert PVS600 central inverters, which are already on the market.
Four new system boxes make it possible to precisely control the Sinvert PVS central inverters from the Siemens Industry Automation Division, connect them to networks and record environmental and meteorological data.
“The central inverter is the core of a PV system. All the relevant data is collected here, and the entire array is controlled from here," says Dr. Ralf Michael Wagner, Head of Systems Engineering at the Siemens Industry Automation Division. “With the new Sinvert PVS system boxes, central inverters can be equipped with additional functions according to customer requirements. Thus, we support operators in the professional monitoring and plant management of their photovoltaic systems.”
The Sinvert ControlBox 300 enables the control of active power and reactive power in large PV power plants with multiple inverter stations via digital ripple control signals. According to statutory regulations such as the Renewable Energy Act (EEG) or the medium-voltage directive issued by the German Association of Energy and Water (BDEW), grid operators must be able to control the performance of the infeeding plant remotely. The Siemens system box constantly records data relating to active power, voltage and frequency of the entire solar park. Based on this data, the device controls any number of inverter stations in a power plant. Depending on demand, the Sinvert ControlBox 300 either ensures a specified active and reactive power for the entire PV plant, or takes over the control according to various characteristics such as Q(U)-, Q(t)- or P(f).
The Sinvert PVS ComBox 100 and ComBox 200 enable quick connection of an inverter to a LAN network. The connection to the Ethernet LAN can be implemented with both devices by means of twisted pair copper cables or fiber optic cables in line or ring topologies. The Sinvert PVS ComBox 200 contains an industrial PC that records, saves and transfers the data of connected inverters to the Sinvert Webmonitor internet portal. The plant operator is then able to check the current status and yield of the PV array remotely via the software.
The Sinvert PVS WeatherStation 200 supplies environmental and meteorological data and thus improves plant monitoring. The weather station has sensors that record the ambient temperature, the insolation as well as the temperature of the solar cells and modules. Optionally, the system box can be expanded by additional sensors for measuring wind speed, wind direction and precipitation. The data acquired by the Sinvert PVS WeatherStation 200 provides information about whether the PV power plant is producing optimum yield and thus helps to optimize plant efficiency.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
