Solar inverters improve the profitability of photovoltaic power plants

29.10.2010
The Siemens Industry Automation Division is further expanding its product portfolio in the power plants segment by introducing the central inverters Sinvert PVS600, PVS1200, PVS1800 and PVS2400.

These four new models cover the 600 to 2400 kilowatt (kW) output range and enable operators of photovoltaic (PV) power plants to tune their inverters precisely to the capacity of the modules employed in the plant. In this way, the yield and efficiency of the entire PV plant can be optimized.

The planning process is supported by Sinvert Select, the cost-free Siemens software application, which is capable of calculating suitable combinations of inverters and PV modules. Sinvert PVS inverters have a peak efficiency of well over 98 per cent, making them some of the most efficient inverters currently available on the market. Equipped with extensive monitoring capabilities, the inverters can also detect faults in the photovoltaic array and thus minimize downtimes.

Four new inverters developed by the Siemens Industry Automation Division with rated outputs from 600 to 2400 kW have now been added to the successful Sinvert PVS product range. With these new additions, Siemens now offers a total of six model series in the power range above 350 kW, thereby providing 24 different configurations of central inverter. With its extensive product portfolio, Siemens can supply inverters designed to optimize the yield of a very broad range of PV modules. The Sinvert Select software application makes module selection easier. As well as applying factors such as location, grid frequency, PV module type and rated output, it also takes account of installation criteria such as tilt angle and south orientation of the PV modules.

Sinvert PVS inverters are designed to make solar power plants very profitable. Their high peak efficiency of 98.6 per cent (eta EU) contributes significantly to their performance. The Siemens inverter models thus outperform the majority of inverters available on the market. Even a 0.2 per cent increase in efficiency significantly boosts the operating yield of a PV power plant. With rated outputs of 1200 kW and above, the master-slave technique guarantees an even load distribution on all components and extends the service life of the inverters substantially. The new Siemens inverters support grid frequencies of 50 and 60 Hz and are thus suitable for operation on any power grid in the world.

The inverters are controlled locally by touch screen. Furthermore, the operator can use standardized communication interfaces to integrate the Sinvert PVS models into a Scada system (Supervisory Control and Data Acquisition) in order to transfer the inverter data to a control center. Thanks to their extensive monitoring capabilities (symmetry monitoring, for example), the inverters can promptly detect faults in the photovoltaic array without the need for additional sensors on the modules. A frequent cause of module or cable failure, for example, are lightning strikes or other weather-related damage. The longer the defect remains undetected, the higher the loss in yield. Depending on its configuration, the Sinvert PVS inverter immediately notifies service personnel of any faults via Internet or SMS, thus minimizing failure times and loss of earnings.

Like all units in the Sinvert PVS range, the new models are optionally available as a turn-key product, installed in a photovoltaic container with all the necessary medium-voltage components. For installation at locations which are especially dry or close to the sea, these containers can be supplied equipped with special dust or salt filters. The new units also comply with the medium-voltage directive issued by the German Association of Energy and Water Industries (BDEW) with all requirements including FRT (Fault Ride Through) and active power control.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
