At the Intersolar trade fair Sputnik Engineering will unveil two new central inverters
New inverters for solar power plants
Biel, 7 June 2010. Sputnik Engineering, based in Switzerland is adding two new central inverters with greater outputs to their new SolarMax TS series.
(firmenpresse) - The new SolarMax 300 TS has a rated output of 300 kilowatts and operates in the MPP range of 430 to 800 volts. This new development is the successful outcome of Sputnik developers' efforts to boost the European efficiency of the previous model, the SolarMax 300 C, from 94.8 to 95.5 percent.
Unlike the SolarMax 300 TS, Sputnik's SolarMax 330 TS SV operates without a low-voltage transformer. As many as four of the new 330-kilowatt inverters can be integrated into a SolarMax power station and their power fed directly into the medium-voltage mains via a medium-voltage transformer. The station can be easily operated using a central control unit. The display clearly shows all the important information and settings.
As with other SolarMax-TS series devices, the electronic system monitors the IGBT switches of the two new central inverters on the power unit, a feature which enhances operational safety and reliability. Sputnik also replaced the electrolyte capacitors with film capacitors wherever possible to add to the devices' useful life. The optional earthing kit also permits the inverters to work in combination with thin-film or back-side contacted modules without a hitch.
The two new central inverters meet all the requirements contained in the BDEW medium-voltage guideline - even those which do not come into effect until 2011. This means the inverters are able to feed in reactive power, to remain on the mains when short-term blackouts occur and, hence, to actively support the grid.
New: Flexible yield optimisation
When looking for the best operating point (MPP), Sputnik customers have the choice: While in single-MPP operation the plant yield in the partial load range is optimised by the output-dependent cut-in of individual power units, creating redundancy as well, the multi-MPP operation with three MPP trackers for each inverter permits installation experts greater flexibility with the plant design. Power losses, which can arise from, say, temporary shading, are minimised.
The new inverters are certified by the TÜV and the VDE Institute. As an option, the two-year standard warranty can be extended for up to 20 years by signing the MaxControl service agreement. Sputnik Engineering will unveil for the first time both of their new developments at the Intersolar trade fair in Munich, which runs from 9 to 11 June.
