Hoymiles DTU-Pro-S — Monitoring Gateway for HMS Microinverters

The Hoymiles DTU-Pro-S is the required monitoring gateway for all Hoymiles HMS microinverter installations. It communicates wirelessly with each HMS unit on the roof, collects real-time production data panel by panel, and uploads it to the Hoymiles S-Miles Cloud for remote access via web or mobile app.

The DTU-Pro-S supports up to 99 microinverters (up to 396 solar panels) on a single gateway — making it suitable for everything from a small residential system to a large commercial array. Setup takes minutes: mount it, connect to Wi-Fi, and your system is online.
