Shutoff device and photovoltaic system

Abstract

A shutoff device, including a shutoff device control chip, where the shutoff device control chip includes a voltage output port, and a configuration module configured to adjust an output voltage of the voltage output port. Since the shutoff device control chip is provided in the shutoff device, and a voltage output port and a configuration module configured to adjust the output voltage of the voltage output port are provided in the shutoff device control chip, the shutoff device output can output different voltage values by configuring the configuration module. In this case, when a connection structure between the shutoff device and the photovoltaic module in the photovoltaic system changes, it is only necessary to reconfigure the configuration module to achieve the purpose of adjusting the output voltage of shutoff device.
