2.The monitoring system of Hoymiles
The DTU is the key component in Hoymiles monitoring system. It is the relay station of
the monitoring system, which operates between the Hoymiles microinverters and the
Hoymiles Monitoring Server. The DTU communicates with the microinverters in the system
via 2.4G RF wireless to collect the data and status of the microinverters in the system. At the
same time, DTU connects to the Internet through WIFI,which realizes the information
exchange with the Hoymiles cloud monitoring service platform and sends all the running
data of microinverters and status of the system to the Hoymiles cloud monitoring server. It
receives the control commands from the cloud monitoring server and sends the data to the
microinverters in the system to achieve remote operation and maintenance.

Other Elements in the Hoymiles Microinverter System
The Microinverter: It converts the DC output of solar modules into grid-compliant AC power.
It sends the output electrical information of PV panels and the operation data of the
microinverters to the DTU, which is the hardware basis of the panel-level monitoring. With
efficiency up to 96.7% and MPPT efficiency up to 99.9%, Hoymiles microinverters rank in the
first level around the world in 2015.
The Hoymiles Monitoring Server: It collects the operation data and status of the
microinverters in the system, and provides the panel-level monitoring for the users and
maintenance staffs t o achieve remote operation and maintenance, which can improve
operational and maintenance efficiency.
