TSOL-MG3-MP
System Introduction
The TSOL-MG3-MP DTU is used in grid-tied applications which is comprised of three key elements:
TSUN RS485 Microinverter. TSOL-MG3-MP DTU. Monitoring System: TSUN Portal Website and TSUN Smart APP . 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.
DTU and microinverters are all connected by RS485 cables. DTU can collect the operating data of microinverters and send control command to each microinverter. DTU has an Ethernet port and an integrated WiFi module. DTU can communicate with the network switch or router by Ethernet cable or WiFi. Users can monitor the power generation of the system by TSUN Smart App and TSUN Portal Website.
DTU can also connect to electricity meter devices, collect power grid information, and control the output power of the photovoltaic system to achieve zero-export function.

DTU also has an external communication interface, which can receive external dispatch commands and regulate output power of the system.

Maintenance Guide
Routine Maintenance
Only authorized personnel are allowed to carry out the maintenance operations and are responsible for reporting any anomalies.
Always use the personal protective equipment provided by the employer when carrying out maintenance.
During normal operation, check that the environmental and logistic conditions are appropriate. Make sure that the conditions have not changed over time and that the equipment is not exposed to adverse weather conditions and has not been covered with foreign bodies.
DO NOT use the equipment if any problems are found and restore the normal conditions after the fault has been corrected.
The firmware version can be checked by using the monitoring system. Do not attempt to dismantle the DTU or make any internal repairs! To preserve the integrity of
safety and insulation, the DTU is not designed to allow internal repairs! Avoid temporary repairs. All repairs should be carried out using only genuine spare parts.
Storage and Dismantling
If the equipment is not used immediately or is stored for long periods, check whether it is correctly packed. The equipment must be stored in well- ventilated indoor areas that do not have characteristics that might damage the components of the equipment.
Take a complete inspection when restarting after a long time or prolonged stop. Please dispose of the equipment properly after scrapping, as component parts are potentially
harmful to the environment, following the regulations in force in the country of installation.
