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.

DTU Installation

System Capacity
The DTU-Pro is capable of monitoring up to 99 panels.
Note: Max. monitoring quantity is for open space, installation condition meets the requirement from both DTU and Microinverter manual, and the distance between  Microinverter and DTU needs to be within the required range.

Basic Conditions Required
Before installing the DTU, ensure that the site meets the following requirements:

• Standard 220 VAC power outlet.
• Stable broadband internet connection.
• Router with Ethernet port.

The environmental requirements for DTU installation:
