DTU-MI Important Safety Information Read this First This manual includes important instructions for installing and maintaining the Hoymiles data transfer unit(DTU-MI). Safety Instructions Note that only professionals can install or replace DTU. Don't try to repair DTU because it contains parts that are not available to users. If DTU is damaged, please send the DTU back to our dealer for repair.
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.
DTU-MI Basic DTU Operation LCD Screen Display at Start Up When the DTU starts up, it goes through the initial boot sequence. During this sequence, the DTU LCD screen displays start-up progress as shown: BOOT SYS setup 10:26:30 System setup…...
DTU-MI Normal Operation When the DTU completes the start up process and obtains the IP address, normal operation begins. During the normal operation, the LCD screen displays the basic operation status of the system, and the two screens shown as below alternate all the time.(screens 1 and 2 will appear when you configure the Internet access).
DTU-MI DTU Local Interface The DTU has an embedded web server, which enables you to view the operation data and status of the system, manage the devices and clear fault locally via a browser. You need to get your computer connected to the same network with DTU to open the DTU local interface in your browser by entering the IP address shown on the LCD screen.
DTU-MI View Project Click “ View ”, appear three options. (1) ViewDTU Information, access to the DTU basic information interface, which contains the following information: www.hoymiles.com...

Client Set item include server address, server IP, server port. Server address: data4.hoymiles.com, Factory settings Server IP: 119.3.25.186, Factory settings Dest Port: 10017, Factory settings (2) ViewSystem Inventory, check the software and hardware version number of the microinverter in the system.
DTU-MI Ground Fault Reset Click “ConfigurationGFDI Fault” to open ground fault manage interface. You can check whether the microinverters have a ground fault or not. If the faults exist, click “Clear Fault”. If the problem persists, please contact our technical support.
DTU-MI Device ID Management During the first-time installation or maintenance of DTU, you need to add or delete the microinverters’ IDs to realize the monitoring of whole system. (1) Manual Config Click “Device IDManual Config”to open manual ID manage interface.
Page 12
DTU-MI You need add the IDs into the blank box shown below manually, and then click “Add ID”. After inputting all of the microinverters’ IDs, you need to click “Reg ID” to finish registration. Then you can see the detailed operating information of system in the Home interface.
DTU-MI (2) Auto Scan Click ”Device IDAuto Scan” to open the auto ID management interface. Click “Scan ID” to start automatic search for microinverters. When the DTU detects all the microinverters’ IDs, you need to click “Reg ID” to finish registration. If the DTU cannot detect all the microinverters in the system over 30 minutes, please use manual mode instead.
Install the PV modules and the microinverters as directed by the installation manuals. 2. Locate the DTU The communication distance of Hoymiles DTU is 200m in the open space. But in the real installation, the environment may be more complex. It may have some obstacles like walls or roofs, which will reduce the communication distance.
