Abstract

The invention is suitable for the technical field of solar photovoltaic power generation, and provides a double-hot-spot protection method and device and terminal device.The double-hot-spot protection method comprises the steps that when a hot spot phenomenon occurs, the position where the hot spot is generated and the breakdown condition of a first Schottky diode are obtained; and performing hot spot protection based on the position where the hot spot is generated and the breakdown condition of the first Schottky diode. According to the invention, dual hot spot protection of the photovoltaic module can be realized simply, conveniently and quickly.

Description

technical field [0001] The present application belongs to the technical field of solar photovoltaic power generation, and in particular relates to a dual hot spot protection method, device and terminal equipment. Background technique [0002] Photovoltaic modules are applied in various environments. It is inevitable that trees, clouds or buildings will partially block photovoltaic modules. At this time, hot spots will occur, and the blocked modules will heat up. In severe cases, the modules will be burned. To avoid the damage to components caused by hot spots, bypass diodes are generally designed. However, in the application environment with severe shading, the bypass diode is used as a hot spot protection component, and the frequency of use increases, and the bypass diode is prone to burn out and breakdown. [0003] The purpose of the present invention is to provide a double hot spot protection means for photovoltaic modules in an environment where shadows often occur. Whe...
