Overall efficiency of grid connected photovoltaic inverters

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 is considered. Based on the static MPPT efficiency and conversion efficiency the overall inverter efficiency is calculated. The dynamic MPPT efficiency is indicated separately.

Gesamtwirkungsgrad von Photovoltaik-Wechselrichtern

Efficacité globale des onduleurs photovoltaïques raccordés au réseau

La présente Norme Européenne fournit une procédure de mesure de l’efficacité de la conversion optimale d’énergie (MPPT – Maximum Power Point Tracking en anglais) des onduleurs, qui sont utilisés dans des systèmes photovoltaïques raccordés au réseau. Dans ce cas, l'onduleur alimente un réseau basse tension avec une tension alternative assignée et une fréquence assignée. L'efficacité de la MPPT tant statique que dynamique est prise en considération. L'efficacité globale de l'onduleur est calculée en fonction de l'efficacité de la MPPT statique et de l'efficacité de la conversion. L'efficacité de la MPPT dynamique est indiquée séparément.

Celovita učinkovitost fotonapetostnih razsmernikov

Ta evropski standard zagotavlja postopek za merjenje učinkovitosti sledenja maksimalni moči (MPPT) razsmernikov, ki se uporabljajo v omrežju povezanih fotonapetostnih sistemov. V tem primeru razsmernik napaja nizkonapetostno omrežje z nazivno izmenično napetostjo in nazivno frekvenco. Upoštevani sta statična in dinamična učinkovitost MPPT. Na osnovi statične učinkovitosti MPPT in učinkovitosti pretvorbe se izračuna celovita učinkovitost razsmernika. Dinamična učinkovitost MPPT je prikazana ločeno.

This European Standard was approved by CENELEC on 2010-04-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.
