Hoymiles DTU-Pro-S (WIFI)

The Hoymiles DTU-Pro-S (Wi-Fi) is a data transfer unit designed for Hoymiles PV microinverter systems, providing reliable communication between microinverters and the S-Miles Cloud monitoring platform. Using Sub-1G wireless communication, the DTU collects module-level operating data and system information from compatible Hoymiles microinverters, while Wi-Fi or Ethernet connectivity enables the collected data to be transferred to the cloud platform. The DTU-Pro-S (Wi-Fi) supports monitoring data from up to 99 solar panels and provides a maximum communication distance of up to 400 meters in open space, making it suitable for residential and small to medium-sized PV installations. It also provides an RJ45 Ethernet interface and RS485 communication interface, with support for Modbus-TCP and Modbus-RTU communication. The device supports local system configuration as well as remote O&M functions such as firmware upgrading and parameter setting. Additional functions include smart zero-export control, power export limiting, PV generation monitoring and load consumption monitoring, helping installers and system operators improve the visibility and management of compatible Hoymiles PV systems.
