Title
(EN) SYSTEM AND METHOD FOR ENHANCED WATCH DOG IN SOLAR PANEL INSTALLATIONS
(FR) SYSTÈME ET PROCÉDÉ DESTINÉ À UNE HORLOGE DE SURVEILLANCE AMÉLIORÉE DANS DES INSTALLATIONS DE PANNEAUX SOLAIRES
Abstract
(EN)
A system and method for automated shutdown, disconnect, or power reduction of solar panels. A system of solar panels includes one or more master management units (MMUs) and one or more local management units (LMUs). The MMUs are in communication with the LMUs with the MMUs and LMUs "handshaking" when the system is in operation. The MMUs are connected to one or more controllers which in turn are connected to emergency detection sensors. Upon a sensor detection of an emergency, the associated MMU is notified which in turn instructs associated LMUs to take appropriate action. In the event that communication with the MMUs has been cut off, the LMUs take the initiative to shutdown, disconnect, or reduce the output of associated string(s) of solar panels.

La présente invention a trait à un système et à un procédé permettant d'obtenir une fermeture, une déconnexion ou une réduction de puissance automatique de panneaux solaires. Le système de panneaux solaires selon la présente invention inclut une ou plusieurs unités de gestion globale (MMU) et une ou plusieurs unités de gestion locale (LMU). Les MMU sont en communication avec les LMU, lesdites MMU et lesdites LMU « établissant une liaison » lorsque le système est en fonctionnement. Les MMU sont connectées à un ou plusieurs organes de commande qui à leur tour sont connectés à des capteurs de détection d'urgence. En cas de détection par un capteur d'une situation d'urgence, la MMU associée est notifiée et à son tour cette dernière instruit les LMU associées de prendre les actions appropriées. Si la communication avec les MMU a été coupée, les LMU prennent l'initiative de fermer, de déconnecter ou de réduire la sortie de la ou des chaînes associées de panneaux solaires.
