Overall efficiency of grid connected photovoltaic inverters; German version EN 50530:2010
Gesamtwirkungsgrad von Photovoltaik-Wechselrichtern; Deutsche Fassung EN 50530:2010
Overview
This European Standard gives a measurement procedure for efficiency of the maximum power point tracking (MPPT) of inverters, which are used in grid-connected photovoltaic systems. In that case, the inverter supplies a low voltage grid with rated AC 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 K 373 "Photovoltaische Solarenergie-Systeme" ("Solar photovoltaic energy systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) of DIN and VDE.
