Hoymiles DTU Gateways
The Data Transfer Unit connects your microinverters to S-Miles Cloud and sets the grid profile.
Hoymiles DTU-PRO-S gateway
The gateways we carry
The DTU collects each microinverter’s data over Hoymiles’ Sub-1G wireless link and forwards it to S-Miles Cloud. It’s also how an installer sets or changes the grid profile.
| Model | For | Connectivity | Warranty |
|---|---|---|---|
| DTU-Pro (WIFI) | HM series | Wi-Fi | 3 years |
| DTU-Pro (4G) — 3-yr data plan | HM series | 4G | 3 years |
| DTU-Pro (4G) — 5-yr data plan | HM series | 4G | 3 years |
| DTU-PRO-S-WIFI | HMS series | Wi-Fi | 3 years |
| DTU-PRO-S-4G — 5-yr data plan | HMS series | 4G | 3 years |
Use DTU-Pro with HM microinverters and DTU-PRO-S with HMS. Confirm capacity and compatibility on the official datasheet.
Good to know: the microinverter runs without a DTU, but you need one to monitor the system and to change the grid profile (e.g., CA Rule 21 → IEEE 1547).
See the DTU & Gateway Guide for setup.
