Hoymiles DTU-WLite-S data transmission unit for HMS microinverters

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 wirelessly collects operating data and transmits it via WLAN to the S-Miles Cloud.

Ideal for private photovoltaic systems, the device enables module-specific monitoring as well as remote access to performance data and system status.

⭐ Highlights/Advantages

• ⭐ Module-specific monitoring of up to 4 PV modules
• ⭐ Wi-Fi 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

Area of ​​application & Target audience

The Hoymiles DTU-WLite-S is suitable for small photovoltaic systems in private areas 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 have a clear overview of your PV system. The data is automatically transferred to the S-Miles Cloud, allowing you to conveniently monitor performance, yield, and status via app or web browser.

Module-level analysis allows for early detection of errors and efficient planning of maintenance measures.

Technology & equipment

The DTU-WLite-S acts as a central interface between microinverters and the monitoring platform. Communication takes place as follows:

• wirelessly via sub-1G radio to the micro-inverters
• via WLAN (802.11 b/g/n) for cloud connection

Installation is done directly via a plug connection with an external power supply. A mobile app supports setup 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 rectified.

The energy consumption is typically only 1.0 W, which keeps the power consumption minimal.{index=0}.

compatibility & System integration

The Hoymiles DTU-WLite-S is compatible with:

• Hoymiles HMS microinverters
• Hoymiles HMT microinverters

It is part of the Hoymiles system of microinverters, DTU and S-Miles Cloud for complete plant monitoring.
