Operators of new systems (> 135 kW) regulated by the German Renewable Energy Sources Act (EEG) or existing systems to be expanded are under the obligation to comply with the prescribed grid parameters. To do this, they need an interface for communication with the network operator. Prior to commissioning, operators must obtain plant certification, an essential component of which is the control concept. Here, the park or power plant controller forms the key link between the telecontrol system of the energy supply company and the power generation unit. This controller requires a component certificate in accordance with technical connection rules VDE-AR-N 4110 and VDE-AR-N 4120. Energielenker solutions is one of the first service providers to offer you full integration of all the necessary components needed to ensure the legal compliance of your operations.
