Problems solved by technology

[0006] However, such a wire connection method has installation inconvenience and reliability problems.
Because usually after the solar cell components and the inverter are fixed separately, the wires of the inverter are connected to the junction box of the solar cell component, which is inconvenient to install; The environment has a great impact, especially in harsh environments such as humidity and high temperature. The wire itself is easily damaged and causes the entire photovoltaic system to fail to work normally or difficult to maintain. Moreover, for large-scale photovoltaic power plants, the use of many power wires will be increased. Conducive to cost control of raw materials and labor installation

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a photovoltaic system, a junction box and a voltage conversion device thereof. Background technique [0002] As a new energy source, solar energy has inexhaustible advantages compared with traditional fossil fuels. Today, as the international energy situation is becoming increasingly severe, various countries have stepped up efforts to develop the solar energy industry, and the application of solar energy has become more and more extensive, such as satellite solar panels in the aerospace field, solar water heaters in daily life, etc. [0003] At present, there are mainly three ways to utilize solar energy, including photoelectric conversion, photothermal conversion, and photochemical conversion. Among them, the most widely used one is photoelectric conversion, which converts sunlight energy into electrical energy. A solar cell is a typical photoelectric conversion de...
