Hoymiles DTU-WLite-S – Gateway for PV monitoring with WLAN
The Hoymiles DTU-WLite-S is a compact data transmission unit for monitoring PV systems with Hoymiles HMS and HMT microinverters. It collects operating data wirelessly and transmits it to the S-Miles Cloud via WLAN.
Ideal for private photovoltaic systems, the device enables module-level monitoring as well as remote access to performance data and system status.
⭐ Highlights / Benefits
- ⭐ Module-level monitoring of up to 4 PV modules
- ⭐ WLAN connection to the S-Miles Cloud for remote access
- ⭐ Plug & Play installation with compact design
- ⭐ Sub-1G radio technology for stable communication
- ⭐ Real-time data and alarm notifications via app
Application area & target group
The Hoymiles DTU-WLite-S is suitable for small PV systems in the private sector as well as for balcony power plants. It is ideal for:
- Private customers with microinverter systems
- Plumbing, heating, and electrical contractors
- New construction and retrofitting of existing PV systems
Everyday benefits
With the DTU-WLite-S, you always keep an eye on your PV system. The data is automatically transferred to the S-Miles Cloud, so you can conveniently monitor performance, yield, and status via app or web browser.
Module-level analysis allows errors to be detected early and maintenance measures to be planned efficiently.
Technology & equipment
The DTU-WLite-S acts as the central interface between microinverters and the monitoring platform. Communication occurs:
- wirelessly via Sub-1G radio to the microinverters
- via WLAN (802.11 b/g/n) for cloud connection
Installation is carried out directly via plug connection with an external power supply. A mobile app supports commissioning and system configuration.
Efficiency & Environment
Through continuous data collection and analysis, the DTU enables optimal use of your PV system. Errors or performance losses can be quickly detected and remedied.
Power consumption is only typically 1.0 W, keeping self-consumption to a minimum.
Compatibility & System Integration
The Hoymiles DTU-WLite-S is compatible with:
- Hoymiles HMS microinverters
- Hoymiles HMT microinverters
It is part of the Hoymiles system consisting of microinverters, DTU, and S-Miles Cloud for complete system monitoring.
