Hoymiles DTU-Pro-S WiFi data transmission unit for HMT / HMS

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

Features

• Stable communication with HMS and HMT 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 makes the system suitable for more complex PV systems. Users can read the data and alarms quickly and easily at the module level. Remote operation and maintenance of the PV system can be conveniently carried out at any time and from any location via the Hoymiles S-Miles Cloud.
