Use open data to power
your solar ecosystem

Data transfer units (DTUs)

A high-performing solar system is more than a source of energy. It’s your source of valuable insights, performance data, and the information you need to live sustainably.

Our data transfer units (DTUs) connect your solar ecosystem with your wider life, bridging useful data together for easier management, faster troubleshooting, and proactive support.

Get robust, real-time data with stable communication

Built for stability, our DTUs take working information and power production data from each of your individual microinverters. As a result, you can see how each microinverter and solar panel is performing, identify potential issues sooner, and analyze your entire solar system in one place.

Deep insights, 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 monitoring faults and performance to adjusting settings and controlling 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 it’s in place, you’ll get regular online updates, options for remote maintenance, and ways to adjust parameters online. Our DTUs even support power export limiting and help you maximize your production.

Connect however you need 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 makes sense for you, from Ethernet to Wi-Fi and 4G.

Choosing your ideal DTU

2.4G or Sub-1G?

2.4G is the most widely used wireless standard, ideal for maximizing compatibility. But Sub-1G boasts unbeatable stability and penetration – ideal if your environment is larger.

Connecting to S-Miles Cloud monitoring

Our DTUs come with a wide range of communication ports. Use Wi-Fi in your home, Ethernet where available for better stability, or 4G if internet access is limited.

DTU and microinverter compatibility

Choose the right DTU for your microinverter series:
●HMS, HMT: DTU-Pro-S or DTU-Lite-S
●MI, HM: DTU-WLite, DTU-Pro, or DTU-W100/G100

Three years’ warranty as standard

For peace of mind throughout the life of your DTU, we provide an extensive 36-month
warranty on all DTUs shipped from January 1st 2022.
