A processor according to an aspect: during monitoring of operation situations, determines that switching to a safety mode is needed; on the basis of the number of all devices connected to photovoltaic (PV) modules and a predefined safety voltage, identifies a target voltage of each of all the devices; and provides a shutdown signal to each of all the devices so that an output voltage of each of all the devices is controlled to the target voltage. Un processeur selon un aspect de l'invention effectue les opérations suivantes : pendant la surveillance de situations de fonctionnement, détermine qu'une commutation vers un mode de sécurité est nécessaire ; sur la base du nombre de tous les dispositifs connectés à des modules photovoltaïques (PV) et d'une tension de sécurité prédéfinie, identifie une tension cible de chacun de tous les dispositifs ; et fournit un signal d'arrêt à chacun de tous les dispositifs de telle sorte qu'une tension de sortie de chacun de tous les dispositifs est commandée à la tension cible. 일 측면에 따른 프로세서는, 운전 상황의 모니터링 중에 안전 모드로의 전환의 필요성을 판단하고, PV(Photovoltaic) 모듈들에 연결된 전체 디바이스들의 개수 및 기 정의된 안전 전압에 기초하여 상기 전체 디바이스들 각각의 타겟 전압을 식별하고, 상기 전체 디바이스들 각각의 출력 전압이 상기 타겟 전압으로 제어되도록 상기 전체 디바이스들 각각에 셧 다운(shut down) 신호를 제공한다.
