Classification: CPC H | IPC H

Claim 0:
1. A module shutdown device, comprising:
a switch transistor, wherein the switch transistor comprises: a first terminal connected to a positive input terminal of the module shutdown device; and a second terminal connected to a negative input terminal of the module shutdown device, wherein the positive input terminal and the negative input terminal of the module shutdown device are configured to connect with a photovoltaic module;
a driving module connected to a control terminal of the switch transistor; and
a power supply module connected to the driving module and an output terminal of the module shutdown device, wherein the output terminal of the module shutdown device is configured to connect to a controller; the controller is configured to send, in order to control the photovoltaic module to output a voltage normally, a first control signal to control the switch transistor to be switched off, and send, in order to stop the photovoltaic module outputting a voltage, a second control signal to control the switch transistor to be switched on; and the power supply module is configured to convert the control signal sent by the controller to supply power to the driving module.
