About Hoymiles Microinverter System

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 in the first class of the world’s Microinverter industry.

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 2.4GHz Proprietary RF (Nordic), 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.

The 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 is capable of monitoring up to 99 pieces of a single unit or 49 pieces of two in one unit or 24 pieces of four in one unit. If the communication between the DTU and microinverter is caused by the installation conditions, the number of PV modules that the DTU can monitor may be reduced.

Basic Conditions Required

Before installing the DTU, ensure the site meets the following requirements:

• Install close to the router.
• Stable Internet reception.
• The straight distance between DTU and Microinverter shall be less than 5 meters.
• The location should be one meter above the ground, 0.8 meters away from the corner.

The environmental requirements for DTU installation:

• Away from dust, liquid, acidic, or corrosive gas.
• Temperature is between -20ºC and 55ºC

Local Install Assistant

Local Install Assistant is a new function integrated with DTU-W100 3rd Gen, please download the Installer App (for installer/distributor use only) first.

http://m.hoymiles.com/download_installer.html

DTU-W100 has improved from the previous generation of DTU products, and developed with this a new function that allows installer:
A. One step to complete the WiFi configuration;
B. Station overall Inverters status indication allows the installer to see how many MI under this
DTU is working properly (and the details for each MI) and how many are abnormal (and the details for each MI) with one glance of the eyes;
C. Add the Connection status, which will display the signal strength between each MI with connected DTU, so that installer can adjust the DTU installation location accordingly. This function will simplify the DTU installation, and avoid the second visit for the installer due to the poor connection between DTU and certain MI.
Note: Please refer to “Hoymiles Local Install Assistant Technical Note” for more details.

System Installation Sequence

The DTU is capable of monitoring up to 99 pieces of a single unit or 49 pieces of two in one unit or 24 pieces of four in one unit.

DTU Installation Procedure

1. Install the PV Modules and microinverters
   Please refer to the Microinverter’s Manual or Quick Installation Guide for the detailed installation steps.

2. Locate the DTU
   The maximum communication distance of Hoymiles DTU is 150m in open space. The walls, roofs, or other obstacles in between will affect the signal and reduce the communication distance in the real installation.
   The range of signal reduction for possible obstacles at the site has been shown below: Material| Relative signal range reductions
   ---|---
   Wood/Glass| 0-10%
   Stone/Pressed cardboard| 10%-40%
   Reinforced concrete (reduction increases with the amount of reinforcement)| 10%-90%
   Metal| Up to 100%

Therefore, the DTU shall be placed as close to the microinverters as possible at the site to ensure good communication between DTU and microinverters.

3. DTU Installation
   a. Connect the DTU to the adapter and plug it into the wall socket. (Figure 1)
   b. If using Power Strip, please make sure it is placed at least 1 meter above the ground and try to install the DTU 90 degrees vertical to the ground as much as possible (figure 2).
   Note： Please do not install the DTU direct above the metal or concrete to prevent the signal dilution.

4. Start Procedure
   Once the DTU is powered on, the red, green, and blue lights will flash every one second in turns for 30 seconds.

5. WiFi Configuration
   Use the smartphone/tablet open the Installer App and log in. Approach “Me” at the bottom of the page and then “Network Configuration”. And input the house router’s Network name and password, click “Send to DTU” to complete the WiFi configuration.
