Overall efficiency of grid connected photovoltaic inverters; German version EN 50530:2010 + A1:2013
Gesamtwirkungsgrad von Photovoltaik-Wechselrichtern; Deutsche Fassung EN 50530:2010 + A1:2013
Overview
This European Standard provides a procedure for the measurement of the efficiency of the maximum power point tracking (MPPT) of inverters, which are used in grid-connected photovoltaic systems. In that case the inverter energizes a low voltage grid with rated AC voltage and rated frequency. Both the static and dynamic MPPT efficiency are considered. Based on the static MPPT efficiency and conversion efficiency the overall inverter efficiency is calculated. The dynamic MPPT efficiency is indicated separately. The responsible committee is DKE/K 373 "Photovoltaische Solarenergie-Systeme" ("Solar photovoltaic energy systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
