The Hoymiles Gateway DTU-Pro is a data transmission unit that collects information and data from PV micro inverters via a 2.4 GHz radio solution and sends it to the S-Miles Cloud, the Hoymiles monitoring platform, via various communication options such as Ethernet or WLAN.

Features

• Stable communication with HM series micro inverters
• Supports RS485, Ethernet port for communication with peripheral devices
• Monitoring and data storage at module level
• Local configuration with S-Miles Toolkit
• Support for remote O&M, including remote upgrade and parameter setting
• Intelligent zero export control and power export limitation
• Monitoring of PV generation and load consumption

How it works

The DTU-Pro data transmission unit has a monitoring capacity for up to 99 solar modules. This means that the system is also suitable for more complex PV systems. Users can read the data and alarms quickly and easily at module level. Remote operation and maintenance of the PV system can be carried out conveniently at any time and from any location via the Hoymiles S-Miles Cloud.

S-Miles account creation

The S-Miles account can only be created via the DTU dealer. We need some information from you to create your account. You can access our online account creation form here. When the account is created, you will automatically receive both user and installer access. The data can only be transmitted and the account created as soon as you have the Micro-Inverter and the corresponding DTU and you can read the serial numbers on the devices.
