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 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 2.4 G 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.

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 staff.
