Read This First

Dear customer, thank you for choosing TSUN products. We hope you will find our products meet your needs for renewable energy. Meantime, we appreciate your feedback regarding our products.

A DTU is a communication device for the TSUN microinverter system. DTU and microinverters are all connected to the same WIFI network. DTU will collect the AC power grid parameter by CT.
If any power is exported to the power grid, DTU will send it to each microinverter and control the output of the system.

This manual contains important instructions for Talent-MG3-MS DTU and must be read in its entirety before installing or commissioning the equipment.
For safety, only qualified technicians, who have received training or have demonstrated skills can install and maintain this DTU under the guide of this document.

Important Safety Information

During installation, testing, and inspection, adherence to all the handling and safety instructions is mandatory. Failure to do so may result in injury or loss of life and damage to the equipment.

Product Label

The symbols on the products are listed below and illustrated in detail.

Symbol	Description
	This device fulfills the requirements of the Radio Equipment Directive.

System Introduction

The Talent-MG3-MS DTU is used in grid-tied applications which not allow electricity to be transmitted to the public power grid, is comprised of three key elements:

TSUN Microinverter.

Talent monitoring system.
Talent-MG3-MS DTU.

The microinverter converts the DC electricity generated by solar panels into AC electricity which is in accordance with the requirements of the public grid and sends the AC into the grid, reducing the load pressure of the grid.
The microinverter is integrated with the Wi-Fi module and connects to the home Wi-Fi router directly. Users can monitor the power generation of the system by Talent monitoring App.
The Talent-MG3-MS/MT DTU will detect the power to the public power grid. If there is an export to the public power grid, DTU will communicate with the microinverter locally and reduce the outpower of microinverters.

- Avoid electromagnetic interference that can compromise the correct operation of electronic equipment.
- Use a mobile phone to check the Wi-Fi signal strength at the installation position. If the Wi-Fi signal is bad, try to install the DTU in another position or move the Wi-Fi router.

Installation Steps

DANGER
- Only qualified personnel should install, troubleshoot, or replace DTU and accessories.
- Before installation, check the unit to ensure the absence of any transport or handling damages.
- Unauthorized removal of necessary protections, improper use, incorrect installation, and operation may lead to serious safety and shock hazards or equipment damage.
- Be aware that installation of this equipment includes the risk of electric shock.

Step 1. Install the DTU.

Fix the DTU onto the rails of AC distribution box. Connect the L and N cable to port 11 and port 14. Then connect CT cable to port 4 and port 5.

Step 2. Connect CT

Install the CT into the L cable. The direction on the CT should be pointed to the microinveter side.

Step 3. Connect the Wi-Fi antenna

Connect the Wi-Fi antenna cable to the DTU. Put the antenna out of the distribution box to get a good Wi-Fi signal.

Step 4. Add the DTU to Talent Home

Open Talent Home App.

Scan the SN label of DTU and add it to the device list.

Step 5. Set the power limit function

Click the setting button and enter the meter setting page.

Switch on the export limit button . Enter the limit power and choose the microinverter that need to control.
Press “Confirm” button. Then the status and relationship will be shown on the device list.
