DTU Hoymiles data transfer units

Data transfer units (DTU)

Use open data to power your solar ecosystem

A high-performance solar system is more than just a source of energy. It's your source of valuable information, performance data and the insights you need to live sustainably.
Our Data Transfer Units (DTUs) connect your solar ecosystem to your wider life, linking useful data for easier management, faster troubleshooting and proactive support.

Get robust, real-time data with stable communication

Designed for stability, our DTUs take working information and energy production data from each of your individual microinverters. As a result, you can see the performance of each microinverter and solar panel, identify potential problems earlier and analyze your entire solar system in one place.

In-depth information, available everywhere

DTUs also bridge the gap between your solar system and the S-Miles Cloud monitoring platform. With this connection in place, you can go beyond fault and performance monitoring to adjust settings and control your system from anywhere in the world. So you can continually optimize performance and maximize your solar harvest.

Painless installation and maintenance

Connectivity at its most compact, your DTU is easy to install, even with limited space. Once in place, you'll get regular online updates, remote maintenance options and the means to adjust parameters online. Our DTUs even support power export limitation, helping you to maximize your production.

Connect the way you want to

For industry-leading resilience and communication, Hoymiles DTUs offer a wide range of connectivity options. For microinverters, use 2.4G wireless as standard, or Sub-1G for increased stability and range. And connect to our monitoring platform in a way that suits you, from Ethernet to Wi-Fi and 4G.
