As many as three SolarMax 330C-SVs can be combined in one megawatt station which can then be directly fed into the medium-voltage grid. With the service package MaxControl plant operators can extend their standard warranty agreement and be sure that Sputnik will immediately recognise and fix plant failures for 20 years.
In the new central inverter SolarMax 330C-SV Sputnik has eliminated the transformer. This technology has already proven itself in all of the Swiss manufacturer's string inverters and in the new SolarMax S series of central inverters. Michael Ernst, the head of central inverter development at Sputnik, explains, "Transformerless engineering has enabled us to reduce the device's size and weight by more than half and to cut costs by 15%." The slimmed-down the SolarMax 330C-SV weighs in at only 1,200 kilogrammes. Another advantage of the transformerless technology is its enormous efficiency. The new device achieves 98%.
Like all other SolarMax inverters, the new device is TÜV type-tested. In addition, SolarMax 330C-SV meets the requirements contained in the BDEW [Federal Association of German Energy and Water Industries] medium voltage technical guideline ("Generating Plants Connected to the Medium-Voltage Network"), which has been in force in Germany since January 2009.
The megawatt station will be unveiled for the first time at the European Photovoltaic Solar Energy Conference and Exhibition EU PV SEC which will take place in Hamburg at the end of September.
