2. The Hoymiles Microinverter System
The DTU is the key component in Hoymiles microinverter system. It works as the gateway,
which is the transfer station of monitoring information in the system. The DTU communicates
with microinverters wirelessly via 2.4G RF, collecting the operating data of the system.
Meanwhile, it sends control commands to microinverters for adjusting the operating state. In
addition, the DTU connects with the Internet to realize the mutual communication of
Hoymiles cloud monitoring platform. The operating data from microinverters and the control
commands from the cloud-monitoring server will be sent through the DTU to the other end.
The remote operation and maintenance are achieved.
The following diagram shows the DTU in the system.
