The invention provides a turn-off system, device and method of a photovoltaic assembly and a readable storage medium. The turn-off system of the photovoltaic assembly comprises a turn-off controller and a turn-off device connected with the turn-off controller. The turn-off controller comprises an AC power supply unit, a power supply switching unit, a charging and discharging unit, a central control unit and a turn-off unit. The input end of the AC power supply unit is connected with a power grid; the first DC output end of the AC power supply unit is connected with the first input end of the power supply switching unit; the second DC output end of the AC power supply unit is connected with the input end of the charging and discharging unit; the output end of the charging and discharging unit is connected with the second input end of the power supply switching unit; the output end of the power supply switching unit is connected with the input end of the central control unit; the outputend of the central control unit is connected with the input end of the turn-off unit; and the output end of the turn-off unit is connected with the turn-off device, so that the turn-off device can turn off a power generation loop of the photovoltaic assembly to prevent the photovoltaic assembly from having fault, and loss is reduced.
Description
technical field [0001] The present invention relates to the technical field of photovoltaic modules, and in particular, to a photovoltaic module shutdown system, device, method and readable storage medium. Background technique [0002] In photovoltaic power plants, more and more shutdown systems are used to shut off the power generation circuit of the components. That is, in the event of an emergency, since the power supply method of the shutdown system is AC power supply from the grid, when the voltage of the grid drops, the power generation circuit is turned off. The shutdown system will immediately shut down, and the shutdown system cannot control the circuit breakers to disconnect the power generation circuit of the components, resulting in serious failures such as component fires and large losses. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a photovoltaic module shutdown system, device, method and readable storage medium, ...
