SMA Solar SMA Data Manager MEDMM-20-DS

For solar farm operators and commercial building managers, the SMA Data Manager EDMM-20-DS serves as the central intelligence for energy monitoring and control. Installed in a technical room or equipment cabinet, it continuously collects data from up to 50 SMA devices—inverters, battery inverters, and energy meters—and streams it to the Sunny Portal for real-time visualization and reporting.

Key specifications

• Manages up to 50 SMA devices via Ethernet (2x RJ45) and RS485 (2x terminal block)
• Integrated data logger with remote firmware updates through Sunny Portal
• Supports Modbus TCP (SunSpec), Modbus RTU, and SMA Speedwire protocols
• Enables active/reactive power control and grid management functions like zero export and dynamic power limitation
• 24 V DC power supply (external PSU not included), typical consumption under 10 W
• Wall or DIN rail mounting, IP20 enclosure, operating temperature -25 °C to +60 °C
• Web-based user interface for configuration and monitoring
• Certified to CE and RCM standards

Why choose it

The EDMM-20-DS streamlines PV system oversight, reducing the need for on-site visits. Its support for open protocols ensures seamless integration with existing SCADA or building management systems, while advanced grid functions help comply with utility requirements and maximize self-consumption.

Ideal use cases

• Commercial rooftop PV arrays requiring dynamic feed-in management
• Utility-scale solar plants needing centralized data logging and remote monitoring
• Energy storage projects where battery inverters must be coordinated with PV generation
• Facilities aiming for zero export or demand charge reduction

Good to know

The device is designed for professional installation; a 24 V DC power supply unit must be sourced separately. It operates reliably in a wide temperature range, making it suitable for unconditioned technical rooms. For commissioning, a web browser is all that's needed—no proprietary software required.
