Hoymiles Microinverter System
Microinverter
It converts the DC output of solar modules into grid-compliant AC power. It
sends the output 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 conversion efficiency up to 96.7% and MPPT efficiency up to 99.9%,
Hoymiles microinverters rank in the first class of the world’s Microinverter
industry.
DTU
The DTU is the key component in Hoymiles microinverter system. It works as the
communication gateway, which operates between the Hoymiles microinverters and
the Hoymiles Monitoring Server. The DTU communicates with the microinverter
wirelessly via 2.4G RF, collecting the operation data of the system.
Meanwhile, the DTU connects to the Internet via router and communicates with
Hoymiles Monitoring Server. The microinverter system operation data will be
uploaded to Hoymiles Monitoring Server via DTU.
Homilies Monitoring Server
It collects the operation data and status of the microinverters in the system
and provides panel-level monitoring for the users and maintenance staff.
The following diagram shows the Hoymiles Microinverter system.
