A group of six solar power plants employing various PV technologies including concentrated solar power (CPV) and with a cumulative output of 6 MW has been installed in the Italian region of Puglia. Alongside CPV technology, the plants also comprise poly and monocrystalline modules. A total of 250 Mastervolt SunMaster CS20s serve as the inverters for all the plant and module technology.
The owner and operator of the plants is the German company Solar 8, which also manufactured the single and dual axis trackers used in the project. Solar 8 used a variety of module technologies to demonstrate the performance of individual trackers in different operating conditions. In order to keep installation and maintenance costs as low as possible, a single inverter model was required that was equally suitable for all the different module types. After initially testing inverters from another supplier, Solar 8's choice settled on the three-phase SunMaster CS20TL RP.
We were very impressed by the yield achieved in the first module batch installed with the Mastervolt inverter, so my partner and I decided to complete the entire 6 MW installation in Puglia using this model, despite having initially tried another solution, says Werner Wieland, CTO of Solar 8.
Mastervolts SunMaster CS family comprises six transformerless inverters with outputs of 7.5, 10, 12.5, 15, 20 and 30 kW. They are characterised by their light weight, compact construction and their high degree of versatility and performance, even in extreme conditions. The CS20 won the prestigious iF product design award in 2010. All SunMaster CS inverters are CEI-021 certified.
