Module Level Power Electronics (MLPE, Module Level Power Electronics) is a PV module level electronic device. 

This device involves a number of cutting-edge technologies such as power electronics, semiconductor device, communication, cloud computing and high-reliability manufacturing. It can perform refined control of one or several modules in the PV system to achieve inversion, monitoring, power optimization, shutdown and other functions. 

At present, it mainly includes microinverter, optimizer and rapid shutdown device, which not only improve the power generation efficiency, but also enhance the reliability and safety of the system.
