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.

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.

Installation
Pre-installation Check
Check the Package
Although TSUN’s products have surpassed stringent testing and are checked before they leave the
factory, it is uncertain that the products may suffer damage during transportation. Please check the
package for any obvious signs of damage, and if such evidence is present, do not open the package and
contact your dealer as soon as possible.
Meter * 1 Antenna * 1 CT * 1 SN Label * 1
Check the Installation Environment and Position
When choosing the position of installation, comply with the following conditions:
Install the DTU near or in the home distribution box.
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.
