Data Transfer Units (DTUs)

Use open data to power your solar ecosystem

A successful solar system is more than a source of energy. It's your source of valuable insights, performance data, and the insights you need to live sustainably.
Our Data Transfer Units (DTUs) connect your solar ecosystem to your wider life, connecting 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 power generation 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 continuously 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 ways to adjust settings online. Our DTUs even support limiting power exports and help you maximize your production.

Connect as you see fit

For industry-leading resiliency 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 works for you, from Ethernet to Wi-Fi and 4G
