Abstract

The invention discloses an automatic turn-off shingle photovoltaic module, which comprises a parallel unit. The parallel unit supplies an external network circuit through an output end. The parallel unit comprises a plurality of battery strings connected in parallel. The output end of each parallel unit is provided with a normally closed switch to control the connection / disconnection state of the parallel unit and the external network circuit. The normally closed switch is normally turned on. When the parallel unit has a fault or receives an external disconnect signal, the normally closed switch is turned off to disconnect the energized line of the parallel unit, thereby protecting the entire circuit system, maintaining the stability of the system voltage, and providing convenience for workers to overhaul the parallel unit.

Description

technical field [0001] The invention relates to an automatic shut-off shingled photovoltaic module, which belongs to the technical field of solar cells. Background technique [0002] Solar energy, as a low-carbon renewable energy, is not only rich in resources, non-polluting to the environment, but also an energy that humans can use freely. Each string of cells in a shingled photovoltaic module is formed by stacking multiple cells. As a conventional module with a large light-receiving area and high voltage, it has become the main development direction today. However, in the shingled photovoltaic module, the series voltage of each battery string is relatively high. In the event of an accident, if the circuit cannot be disconnected in time, the system voltage will cause injury to rescuers. With the continuous expansion of the photovoltaic industry, the probability of accidents is also increasing. Therefore, in order to improve the safety of the photovoltaic system, American c...
