MAKING MODERN LIVING POSSIBLE Ground Voltage Control Maximise your thin film plant performance with powerful transformerless inverters With a Danfoss Ground Voltage Control solution (GVC) you can now use thin film and crystalline backside contacted PV cells with Danfoss transformerless string inverters. Maximise the performance ratio of your thin film plant Benefit from the simplicity of decentralised string installations You now need just one inverter range for all panel types A tried and tested Danfoss solution you can trust Thin film performance ratio improved with the advantages of transformerless string inverters Improved performance ratio Innovative GVC technology allows you to use highly efficient, transformerless inverters with your thin film or crystalline backside contacted arrays – with no corrosion risk and no PV string grounding required. Simplicity with decentralized string installations Improve the power density of your plant. A centrally grounded Danfoss GVC solution works with one to a hundred inverters. One range for all panel types With a GVC solution, just one product range is required for all your applications. Reduced training costs and a single supplier make a GVC enabled solution an economically smart investment. Tried and tested solution A GVC solution is a simple add-on to the familiar TLX inverter range, the TLX, TLX+ TLX Pro and TLX Pro+. After 18 months of field testing, the Danfoss GVC has proven its value in installations up to 1MW.

*)A typical installation with 70 TLX 15 Inverters and thin film modules requires 30mA DC for operation. Therefore the GVC Input power will be a round 20VA. The moduletypes, the Insulation resistance and weather conditions have an Influence on the required operation current This will also Influence the maximum possible number of Inverters per GVC In turn, this means 100 Danfoss Inverters are not possible In every Installation. GVC System voltage level polarisation effects Picture shows earthed string voltages and how GVC compensates for polarisation effects and TCO corrosion. The PVvoltage...
