Inverters and photovoltaic modules together form a power generation system

Inverters occupy a downstream position in the photovoltaic industry chain and together with components form the power generation system. The photovoltaic industry chain can be divided into five links: silicon materials, silicon wafers, photovoltaic cells, photovoltaic modules, and photovoltaic systems. The upstream includes the production of high-purity polycrystalline silicon materials, the manufacturing of monocrystalline silicon and polycrystalline silicon, and the production of silicon wafers. The midstream includes photovoltaic cells, photovoltaic modules (glass, brackets, etc.) and other links. The downstream includes the inverter and photovoltaic power generation system links, and the inverter plays an important role in the entire photovoltaic industry chain.

 

Photovoltaic inverter is the heart of solar photovoltaic system, its main function is to convert the direct current generated by solar cell modules into alternating current, and integrate it into the power grid or supply it to the load. A photovoltaic inverter is a power electronic device that connects solar photovoltaic panels to the grid. Its main function is to convert the direct current generated by solar panels into grid connected alternating current through power modules. It is the "heart" of a solar photovoltaic power generation system.

 

The reliability and safety of photovoltaic inverters are directly related to the overall smooth operation of solar power generation systems. Their conversion efficiency directly affects the power generation efficiency of solar photovoltaic power generation systems, and their service life is directly related to the service life of photovoltaic power generation systems, ultimately affecting the investment return rate of photovoltaic power station projects. Photovoltaic inverters not only have the function of converting DC electricity to AC electricity, but also have the maximum power tracking function (MPPT), as well as maximizing the performance of solar cells and protecting photovoltaic power generation systems.
