General about Microinverter System

The Microinverter
It converts the DC output of solar panels into grid-compliant AC power. It sends the output information of solar panels and the operation data of the microinverters to the WiFi Stick (DTU), which is the hardware basis of panel- level monitoring.

The WiFi Stick (DTU)
The DTU is a key component in the microinverter system. It works as the communication gateway between the Hoymiles microinverters and the S-Miles Cloud (Hoymiles Monitoring Platform). The DTU communicates wirelessly with the microinverters via 2.4 GHz Proprietary RF (Nordic), and collects the operation data of the system. Meanwhile, the DTU connects to the Internet via the router and communicates with the S-Miles Cloud (Hoymiles Monitoring Platform). The microinverter system operation data will be uploaded to the S-Miles Cloud (Hoymiles Monitoring Platform) via DTU.

The S-Miles Cloud (Hoymiles Monitoring Platform)
It collects the operation data and status of the microinverters in the system and provides panel-level monitoring for users.

Installation

System Capacity
The DTU can monitor up to two micro-inverters with a maximum of four solar modules. If the communication between the DTU and the microinverters suffers interference caused by installation conditions, the number of solar panels that the DTU can monitor may be reduced.

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

• Install the DTU close to the router.
• Stable Internet connection.
• The straight distance between the DTU and the microinverter must be less than 10 meters.
• The location should be 1.0 meters above the ground and 0.8 meters away from corners.
• Environmental requirements for DTU installation:
• Away from dust, liquid, acids, or corrosive gas.
• The temperature should be between -20ºC and 55ºC.

Installation procedure

Preparation

1. Solar panels and Microinverter should be already installed and connected to the house grid.
2. Find the best location for DTU.
   The maximum communication distance between DTU and the microinverter is 150 m, maximum communication distance between DTU and the router is 10m in open space. The walls, roofs, or other obstacles in between will affect the signal and reduce the communication distance in actual installations.
   The range of signal reduction for possible obstacles at the site is shown below:

10%-90%
Metal| Up to 100%

• Therefore, the DTU must be placed as close to the microinverter as possible at the site to ensure good communication between the DTU and the microinverter.

• Connect the DTU to the adapter and plug it into the wall socket, like below.

• If using a power strip, make sure that it is placed at least 1 meter above the ground, and try to install the DTU at a 90-degree angle perpendicular to the ground, like below.

• Once the DTU powers on, the red, green, and blue lights will flash in sequence for one second each for 30 seconds.
