Certification

Power generation systems on the medium, high and extra-high voltage grid in Germany are subject to mandatory certification in accordance with NELEV and VDE-AR-N 4110/4120 (TAR Medium and TAB High Voltage), regardless of the respective technology (wind, photovoltaics, VKM/CHP, storage, hydropower). The guidelines oblige system operators to submit a system certificate to their responsible energy supply company. This applies to systems with a connected load greater than 135 kW with a connection to medium or high voltage grids. Systems connected to the low-voltage grid only have to submit unit or component certificates. We would like to assist you with your certification process and introduce you to the accredited certification of electrical properties. Starting with the unit certification of the generation units for manufacturers, which forms the basis of the system certification for project planners, continuing with the certification of the components through to the final EZA declaration of conformity, we will provide you with the corresponding proof.

We have illustrated the process from the system certificate to the EZA declaration of conformity in a short video:

We have trained employees for all topics who will be happy to help you. If you have any questions, please do not hesitate to contact us. Here you will find an overview of the topic of system certification / unit certification.
