Vde-ar-n 4105 English Pdf [upd]

VDE-AR-N 4105 is the German technical connection rule for power generation systems (like solar PV or battery storage) connected to the low-voltage distribution network. It ensures that small-scale energy systems support grid stability rather than disrupting it.

3.4 Active Power Feed-in Management

Systems with a power output $> 4.6 \text kVA$ (and in some cases smaller ones depending on local regulations) must be equipped with a device that allows the grid operator to remotely curtail the active power feed-in. This is usually realized via a ripple control receiver (Rundsteuerempfänger) or a communication interface.

Always cross-check critical parameters with the original German if you face a legal dispute with a grid operator.

1. Introduction

VDE-AR-N 4105 is the German Application Rule published by the VDE (Association for Electrical, Electronic & Information Technologies). It defines the technical requirements for connecting and operating power generation systems (such as photovoltaic systems, CHP units, and wind turbines) in parallel with the public low-voltage electricity grid ($U_n \leq 1kV$).
