New products at the 26th Photovoltaic Symposium in Bad Staffelstein
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.
