VDE-AR-N 4110: Power feed-in to the medium-voltage grid

If you are planning to feed power into the medium-voltage grid with a decentralized generation plant (EZA), you cannot avoid the VDE-AR-N 4110.

Since April 27, 2019, this technical connection rule has been mandatory for the planning and construction, operation, and changes to customer systems of types B (135 kW ≤ PAmax ≤ 950 kW), type A (PAmax > 950 kW), and type C (individual verification procedure) and legally binding as a minimum standard. The target group of the guideline is primarily network and system operators as well as system and component manufacturers.

Requirements of VDE-AR-N 4110

In its current version, VDE-AR-N 4110 describes the following requirements and the basic verification procedure on 215 pages

  • Technical requirements for systems (e.g., voltage levels, protective devices, measuring devices)
  • Registration and connection of systems
  • Operation and maintenance of systems
  • Changes to systems
  • Certification of systems

Based on VDE-AR-N 4110, MKH Greenergy Cert GmbH, as an accredited certification body, creates system certificates for all types of decentralized EZA.
