Integration of decentralized producers into the low voltage system
The installed capacity of decentralized power production units (in particular PV and small CHP systems) has soared in recent years. The VDE standard VDE-AR-N 4105 defines the requirement for integration of power production units into the low voltage system.
The standard VDE-AR-N 4105 is relevant for the German market and is a necessary requirement if you as a manufacturer would like to enter it. With our VDE-AR-N 4105 certification, we ensure you a smooth entry into the German market.
Soon, other standards will be developed which will be required for different countries. We at TÜV SÜD will be also prepared for these upcoming standards to test your devices in our laboratory.
The guidelines and standards applicable to date have not yet given sufficient consideration to the growing relevance of production systems for the low voltage system. To ensure power system stability, the VDE FNN has developed an application guide providing for responses and countermeasures that can be implemented to stabilize the quality of electricity supply in critical phases in the power distribution network. With respect to PV systems, the standard VDE-AR-N 4105 came into effect for all new systems on 1st January 2012; for all other production units it will become binding when these units are first connected to the grid from 1st July 2012 onwards.
Manufacturers of power generation units which feed energy into the low voltage system, e.g.
- Manufacturers of inverters
- Manufacturers of small CHPs
We test and certify your energy production units for conformity with the VDE-AR-N 4105 guide.
