  • the present invention further relates to a removable communication unit, in particular for use in such a modular system.
  • the measuring systems conventionally used in photovoltaic plants for measuring at least a current are based on either sensors measuring voltage drop across shunts or hall-effect sensors.

  • the solutions available in the market nowadays provide, depending to the type of unit, configuration settings by dip-switches or using a communication port and suitable software.
  • Such conventional control solutions have a plurality of disadvantages.
  • Shunts and sensors require space on the electronic boards in the string box or combiner box of a respective system. Therein, shunts and sensors have to be mounted or soldered individually on the PCB.

Abstract

Le module électronique (1) comporte des connecteurs (8, 10) permettant une connexion à d'autres modules électroniques (identiques ou similaires). Le module électronique (1) forme, individuellement ainsi qu'en association avec une pluralité de modules électroniques (1) interconnectés, une barre omnibus parallèle. Le corps principal (2) du module électronique (1) est constitué d'un matériau conducteur, tel que le cuivre. Des trous (4, 5) dans les connecteurs (8, 10) permettent de fixer les connexions à l'aide de vis. Le courant peut circuler à partir de chaînes photovoltaïques par l'intermédiaire de pôles d'entrée (11) respectifs vers la barre omnibus. Chaque pôle d'entrée (11) est pourvu d'un shunt (12). En vue de déterminer un courant, la chute de tension à travers chaque shunt (12) est mesurée.
