2. About Hoymiles Microinverter System
2.1 The Microinverter:
It converts the DC output of solar modules into grid-compliant AC power. It
sends the output information details 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 into the first class of the world’s Microinverter industry.
2.2 The 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
or GPRS and communicate with Hoymiles Monitoring Server. The microinverter system operation
data will be uploaded to Hoymiles Monitoring Server via DTU.
2.3 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.
