Hoymiles DTU-Pro-S Gateway: Professional Module-Level Solar Monitoring & Control

The Hoymiles DTU-Pro-S is the essential communication bridge for your solar array, engineered specifically for the HMS and HMT series of microinverters. Unlike standard Wi-Fi bridges, the Pro-S utilizes Sub-1G wireless technology, providing superior signal penetration through walls and roofs to ensure your solar data remains uninterrupted, even in complex residential environments.

With the DTU-Pro-S, you gain access to the S-Miles Cloud platform, where you can view real-time, panel-level production data from your smartphone or desktop. This gateway is more than a logger; it is a vital tool for remote troubleshooting, allowing you to identify a single underperforming panel or shaded module without ever stepping onto a ladder.

Key Features & Performance Benefits:

• Sub-1G Wireless Communication: Provides industry-leading stability and range, ensuring the gateway maintains a lock on your microinverters across large properties.
• Module-Level Data: Track the exact kWh production of every individual solar panel, helping you maximize your ROI and spot shading issues instantly.
• Remote Maintenance: Perform firmware updates and system configurations remotely via the S-Miles toolkit, reducing the need for on-site service calls.
• Grid Export Control: Essential for net-metering compliance; the Pro-S allows you to set zero-export limits or power export management.
• Flexible Connectivity: Supports local Wi-Fi, hardwired Ethernet, or 4G cellular (optional) for constant cloud synchronization.
• Multi-Inverter Support: A single DTU-Pro-S can monitor up to 99 solar modules, making it ideal for both residential and light commercial projects.

Technical Tip: For the most stable connection, place the DTU-Pro-S within 50 feet of your solar array and avoid placing it near thick metal obstructions. Use the hardwired Ethernet port whenever possible to ensure 24/7 uptime for your net-metering reporting.
