The VDE-AR-N 4105 application guideline in force since 01.01.2012 stipulates that photovoltaic installations larger than 30kVA must be equipped with central grid and network protection at the central meter location. Due to the rapid growth in the number of decentralised power generation plants in Germany, additional measures have to be implemented in order to further ensure the stability of the grid. The VDE-AR-N 4105 application guideline includes the following measures: When the low-voltage grid is subject to impermissible voltage or frequency deviations, generator plants must be disconnected.
