Powador is CO2-neutrally produced and it is a three-phase device. It has a maximum efficiency of 97.8% and can be supplied in a triple configuration as a megawatt power station. Its topology was conceived without a transformer, the company said. PV system designers can select a suitable transformer in accordance with their grid-connection conditions.
Previous master-slave connections, the same inverter always took on all the work with low solar irradiance, with the KACO megawatt power station, all three devices are alternately used as the master. This alternating master solution will increase the service life, said KACO new energy.
Matthias Haag, member of the management board and the technical director of KACO new energy said Large-scale PV systems are playing an increasingly important role in Germany and, in particular, Italy. The U.S. and the Czech Republic also have considerable potential.
