Innovations for the Markets of the Future PHOTOVOLTAICS CENTRAL INVERTERS Innovations for the markets of the future Are there any new developments in the central inverter market segment? How do companies assess their future prospects in this segment? What markets are they eyeing and what products do they have in their lines? SUN & WIND ENERGY posed these questions to a number of manufacturers and presents an overview of central inverters.

Photo: Fronius International Like its 1.1 MW predecessor, it includes all of the necessary components, so that all that is left to do is connect the PV plant and install the grid connection from the integrated transformer.” In the German- speaking region, and in many other parts of Europe, Schlumberger does not see any great opportunities at present. “We see good market opportunities in North and South America, as well as in the Middle East and Asia. However, customer-specific equipment adaptations present major challenges.” The Austrian manufacturer Fronius International sees new requirements for central inverters installed out- doors. “Basically, the issue is the variety of environ- mental factors, such as sunlight, rain and snow to which the devices are exposed,” writes Andrea Schartner, Team Leader of Communications. “Our outdoor central inverters already meet these high re- quirements. In addition, at Fronius, development is ongoing. Our tests exceed the standards, particular- ly in the area of quality.” Thanks to new markets in the USA, Australia and India, the company sees great potential and therefore is developing central inverters “Europe is likely to remain an important market for specifically for this segment which meet the needs of photovoltaics and thus also for central inverters.

  • Solarcentury Installs a 5 Megawatts Solar Park in Great Britain Using Solarmax Inverters
    Press release Solarcentury installs a 5 megawatts solar park in Great Britain using SolarMax inverters One of the largest solar parks in Great Britain has sprung up on Mingay Farm in Cambridgeshire. The British company Solarcentury installed the 14 hectare park with an output of five megawatts. Biel, 16.08.2011 : In the County of Cambridgeshire solar radiation is good, comparable with that in the south of Germany. The 19,960 solar modules installed in the Mingay Farm project generate enough energy to supply up to 1,200 homes and the solar power station will save 55,000 tons of carbon dioxide in 25 years. Solarcentury designed the system using 14 SolarMax 330TS-SV devices for the inverters. They feed their power directly from the SolarMax power station into the local energy supplier's medium voltage network. The inverters are particularly long-lasting and reliable thanks to the use of film capacitors and the intelligent monitoring of power semiconductors. With a maximum efficiency of 98 percent they also work very productively, which is confirmed by Jan Muller, Head of Technology at Solarcentury: "The SolarMax inverters have proved to be exceptionally efficient and powerful", says Muller. "What we also really appreciate is the technical support and advice by Sputnik that we can always rely on during the development and implementation of our projects." That is why Solarcentury is also trusting in Swiss quality products from Sputnik Engineering AG for its follow-up projects. The British company does not just want to use more SolarMax inverters in Great Britain but also in Italy, France and Spain.

  • Press Release the Largest Private Solar Power Plant In
    Press release The largest private solar power plant in the UK starts operation with Sputnik inverters Biel, 02.11.2010 . Today, Solarsense UK Ltd. starts operating Britain's largest private solar power plant. Solarsense has installed the 200 kilowatt plant on the cowhouse of the Worthy Farm in the town of Glastonbury in southern England. The grounds are used as a venue for Europe's largest open-air music festival, attended by roughly 200,000 guests from all over the world. "Our portfolio perfectly matches the individual segments of the important British photovoltaic market. That is why we are so pleased that this impressive project has also been fitted with SolarMax inverters,“ said Daniel Freudiger, General Manager of Sputnik Engineering International AG and Head of Sales & Marketing at the company's Swiss headquarters in Biel. Solarsense has purchased the inverters from Sundog Energy Ltd., one of the leading British companies for renewable energy systems. In Glastonbury two SolarMax TS series central inverters convert the direct current from more than 1,100 solar modules into grid-compliant alternating current. The yield is enough to supply 40 households with energy. In addition, the solar plant eliminates 100 tons of carbon dioxide emissions every year. "We decided in favour of Sputnik Engineering for our inverters because of their high quality," explains Kerry Burns, General Manager of the company which operates the system, Solarsense UK Ltd. "Besides, the price/performance ratio of the devices and the plant monitoring convinced us as well.“ Solarsense installed the internet-based data logger MaxWeb xp which warns Burns and his employees by SMS in case of an error.

  • Commercial News Lyss, 4 May 2011
    Commercial News Lyss, 4 May 2011 3S Photovoltaics supplies solar modules for Umwelt Arena roof What is to date Switzerland's largest building-integrated photovoltaic installation incorporates the trend-setting integrated MegaSlate® roof system from 3S Photovoltaics, a member of Meyer Burger Technology Ltd [Ticker: MBTN]. Installation is the responsibility of BE Netz, while Sputnik, based in Biel, is the inverter supplier. The three companies involved are also providing their expertise about architectural photovoltaics in the exhibition area of Umwelt Arena, Switzerland's first centre of excellence for the environment, which is being built in Spreitenbach near Zurich. As of spring 2012, Umwelt Arena's roof, which has an area of 5,300 m², will generate approx. 540'000 kWh of solar power per year, roughly corresponding to the annual consumption of 120 households. This power will be generated by 5,239 solar laminates produced by 3S Swiss Solar Systems and installed on a total of 33 differently oriented trapezoidal "facets" of the roof. Joint project by Swiss companies BE Netz, based in Lucerne, is responsible for installing the system, while a third well-known Swiss company, Sputnik Engineering, is supplying the inverters for this installation which is to date the only one of its kind in Switzerland. 3S Swiss Solar Systems, which distributes its building-integrated solar systems under the 3S Photovoltaics brand, has already carried out numerous successful joint solar projects with BE Netz. The MegaSlate® solar roof system is fitted as standard with SolarMax inverters from Biel-based Sputnik. Unique architecture combined with environmental technology As Swiss pioneers in the practical implementation of solar energy supply, these three companies are delighted to be working together on this major project.

  • Sputnik Engineering Presents Maxtalk 2 and Enhances the Flexibility of Its Solarmax-MT Inverter
    Press release Sputnik Engineering presents MaxTalk 2 and enhances the flexibility of its SolarMax-MT inverter New products at the 26th Photovoltaic Symposium in Bad Staffelstein Biel, 24-02-2011. At the 26th Symposium on Photovoltaic Solar Energy in Bad Staffelstein from 2 to 4 March Sputnik Engineering is presenting its new communications software MaxTalk 2. This tool monitors and manages the measured values of any number of solar power plants fitted with SolarMax inverters. Users can query the present status of their solar power plant, the operating data, statistics, measured values and device parameters. In comparison to the previous version (MaxTalk), the user guidance of MaxTalk 2 has been greatly enhanced. The new professional version MaxTalk 2 pro also permits registered installers additional configuration options to meet the requirements contained in the medium-voltage guideline of Germany's Federal Association of Energy Suppliers and Water Utilities applicable to solar plants in Germany from April 2011. More flexibility for plant layouts Sputnik Engineering has increased the flexibility of SolarMax MT string inverters, introduced in 2010, (rated output: 10, 13 and 15 kW) , to allow for greater flexibility during plant layout. Instead of six kilowatts of generator output per MPP tracker, it is now possible to connect a maximum of nine kilowatts of generator output. This will give installers the freedom, as when wiring the 15-kilowatt inverter SolarMax 15 MT, to connect either two module strings each with nine kilowatts DC output to the inverter or, alternatively, to select a symmetrical division of three times six kilowatts. In between these two, any combination is possible, as long as the voltage and current limits stated in the data sheet are observed.

  • Solarmax 330TS-SV Receives BDEW Unit Certificate
    Press release SolarMax 330TS-SV receives BDEW unit certificate Most powerful central inverter of Sputnik Engineering meets the criteria of the BDEW Medium-Voltage Directive. Biel, 18 August 2011 : Newly commissioned grid-coupled inverters equipped with a direct medium- voltage connection in Germany must demonstrate their compliance with the directive “Generator plants on the medium-voltage network” by means of a unit certificate of the BDEW (German Association of Energy and Water Industries). The SolarMax central inverter 330TS-SV has now received this certificate. Evaluation and certification were implemented via the accredited Fraunhofer Institute for Solar Energy Systems and the certification institute Bureau Veritas. For example, the BDEW directive requests that photovoltaic inverters must no longer shut down in the event of a short-term failure of the mains network, but must support the mains network in a dynamic manner. Furthermore, photovoltaic systems must also provide a contribution in the field of static voltage maintenance in the future by delivering and receiving reactive power in order to be able to compensate for voltage fluctuations within the mains network. The fact that the SolarMax 330TS-SV has these capabilities is confirmed by the unit certificate. “The field of photovoltaics has developed from being a hobby of individuals to become a cornerstone of the German energy supply. Therefore, it is logical that it must also provide a contribution to the system services of the electricity grid. The Medium-Voltage Directive ensures that the development in the field of photovoltaics can be continued in the future as well,” says Hans-Thomas Fritzsche, General Manager of the German subsidiary of Sputnik Engineering in Neuhausen, Germany.

  • Optimise Costs, Increase Revenues Markets Are Different
    PHOTOVOLTAICS CENTRAL INVERTERS Optimise costs, increase revenues Markets are different But the markets are subject to different conditions, according to Casini: investors and operators in Asia accept shorter maintenance cycles with increasing personnel requirements if the initial cost is low. In Europe and North America, the situation is exactly the opposite, because here the labour costs are higher. “In order to offer the right solutions for each market, Power-One will continue to diversify its product port- folio and include central inverters for both mature and emerging markets,” says Casini. Schweikardt of Sputnik is thinking more of the German market when he says that an investment in PV has to be profitable despite reduced funding, and that it is therefore important that an investor can get the greatest possible amount of energy at the lowest possible cost. For this reason, it is not only Sputnik that is trying to accommodate more powerful central inverters in a station solution, thereby reducing the number of stations needed as well as the acquisition cost. “In addition, we think it is very important,” Schweikardt continues, “that our products can be in- stalled quickly and easily to keep time and material Photo: REFUsol costs as low as possible.” More capacity in the same space – with this strategy, News from the manufacturers manufacturers of central inverters intend to help reduce However, many manufacturers are not just working the investment costs of PV power plants.
