How does the TSUN DTU improve system monitoring?

The DTU connects to all microinverters, collecting real-time data on energy production and system performance. Users can remotely monitor and manage their solar system via an app, ensuring efficient energy use and detecting any issues quickly.

What is the benefit of the DTU’s zero-export control?

The DTU prevents excess energy from being fed back to the grid by regulating the system output and aligning power generation with consumption, which maximizes self-consumption and reduces wastage.

Can the DTU be used for larger solar setups?

Yes, the DTU supports up to 64 microinverters, making it suitable for both residential and commercial solar systems, ensuring scalability and effective management across various installations.

DTU

Built-in Wi-Fi & RS485 & RJ45

DTU is a power control device for RS485 microinverters. DTU can collect the AC

grid data from the RS485 power meter. At the same time, DTU communicates

with microinverters and controls the output power of the entire microinverter system.

Data Collection

DTU can be used with RS485 microinverters to monitor the operating status of the microinverters.

Zero export

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.

Remote dispatch

DTU also has an external communication interface, which can receive external dispatch commands and regulate output

power of the system.
