VDE-AR-N 4105 (2018-11) is a German technical application rule defining requirements for generating plants (including photovoltaic, battery storage, CHP) connected to the low-voltage grid (up to 1,000 V AC).
It superseded earlier standards like VDE 0126-1-1 and aligns with DIN VDE V 0124-100 (EEG requirements). vde-ar-n 4105 english pdf
