Decision-making aid for the application of VDE-AR-N 4105, VDE-AR-N 4110 and the FNN note Simplified connection according to NELEV and EAAV
Are you planning to connect a generation system to the grid and wondering what steps you need to take to ensure successful commissioning? The following decision-making aid is intended to help you as a connection recipient to provide the correct proof to the grid operator regarding the grid connection of a generation system. Due to the different types of generation units (type 1, type 2 and storage units), the fact that several generation plants and storage units can be connected to one grid connection point and the NELEV Amendment Ordinance and EAAV, the correct provision of the required proof can be very complicated for connection recipients. We will guide you through the jungle of directives:
The system is connected in accordance with VDE-AR-N 4105 (TAR Low Voltage). No system certificate is required.
The system is connected in accordance with the technical design as per FNN note NELEV. No system certificate is required, no higher-level decoupling protection is required.
The system is connected in accordance with the technical design as per FNN note NELEV. No system certificate is required, but higher-level decoupling protection and PAV,E monitoring are.
The system is connected in accordance with VDE-AR-N 4110. No system certificate is required.
The system is connected and the units are set in accordance with VDE-AR-N 4105. No system certificate is required. The system must be designed with higher-level decoupling protection.
The system is connected and the units are set in accordance with VDE-AR-N 4110. A system certificate must be submitted.
Please note that the results of the decision aid are not guaranteed. We recommend that you always consult the network operator.
