Data sheet and name plate for photovoltaic inverters

This European Standard describes data sheet and name plate information for photovoltaic inverters in grid parallel operation. The intent of this document is to provide minimum information required to configure a safe and optimal system with photovoltaic inverters. In this context, data sheet information is a technical description separate from the photovoltaic inverter. The name plate is a sign of durable construction at or in the photovoltaic inverter. The name plate may be inside the photovoltaic inverter only if the name plate is visible once a door is opened in normal use.

Datenblatt- und Typschildangaben von Photovoltaik-Wechselrichtern

Diese Europäische Norm beschreibt die Datenblatt- und Typschild-Angaben für Photovoltaik-Wechselrichter zum Netzparallelbetrieb. Sie stellt ein Minimum an Informationen unter der Maßgabe bereit, ein sicheres und optimales System mit Photovoltaik-Wechselrichtern zu ermöglichen. Dabei ist unter dem Datenblatt eine vom Photovoltaik-Wech¬selrichter getrennte technische Beschreibung zu verstehen. Das Typschild darf sich innerhalb des Photo¬voltaik-Wechselrichter befinden, sofern es sichtbar ist wenn eine Tür im normalen Betrieb geöffnet wird.

Fiche technique et plaque d’identification pour les onduleurs photovoltaïques

La présente Norme Européenne décrit les informations contenues dans la fiche technique et sur la plaque d’identification des onduleurs photovoltaïques fonctionnant parallèlement au réseau. L’objet de ce document est de fournir les informations minimales requises pour configurer un système sûr et optimal avec des onduleurs photovoltaïques. Dans ce contexte, les informations des fiches techniques correspondent à une description technique distincte de l’onduleur photovoltaïque. La plaque d’identification est un signe d’une construction durable, sur ou dans l’onduleur photovoltaïque. La plaque d’identification ne peut se trouver dans l’onduleur photovoltaïque que si celle-ci est visible lorsqu’une porte est ouverte en utilisation normale.

Predstavitev tehničnih podatkov in napisne ploščice za fotonapetostne razsmernike

Ta evropski standard opisuje tehnične podatke in napisne ploščice za fotonapetostne razsmernike pri vzporednem omrežnem obratovanju. Namen tega dokumenta je podati minimalne informacije, ki so potrebne za konfiguracijo varnega in optimalnega sistema s fotonapetostnimi razsmerniki. V tem okviru predstavljajo tehnični podatki tehnični opis, ločen od fotonapetostnih razsmernikov. Napisna ploščica je znak trpežne konstrukcije, ki se nahaja na ali v fotonapetostnem razsmerniku. Napisna ploščica je lahko v fotonapetostnem razsmerniku le, če se vidi takoj po odpiranju vrat pri običajni uporabi.

1 Scope
This European Standard describes data sheet and name plate information for photovoltaic inverters in
grid parallel operation.
The intent of this document is to provide minimum information required to configure a safe and optimal
system with photovoltaic inverters.
In this context, data sheet information is a technical description separate from the photovoltaic
inverter. The name plate is a sign of durable construction at or in the photovoltaic inverter. The name
plate may be inside the photovoltaic inverter only if the name plate is visible once a door is opened in
normal use.
