SMA Data Manager M EDMM-20 | Smart PV System Controller for Export Limitation

SMA Data Manager M — EDMM-20

The SMA Data Manager M (EDMM-20) is a professional system controller and data logger for commercial PV and hybrid systems. It centralises monitoring, secure grid-compliant control and remote parameterisation for up to 50 devices, integrating PV inverters, battery inverters, meters, sensors, I/O systems and EV charging. Designed for reliability and future-proof scalability, it works seamlessly with Sunny Portal powered by ennexOS for portfolio-level insight and reporting.

• Scalable control: Supports up to 50 devices; 2.5 MVA closed-loop control or 7.5 MVA open-loop/monitoring.
• UK grid compliance: Export limitation compliant with EREC G100/2; works with G99-type-tested SMA inverters.
• Fast commissioning: Built-in Wi-Fi access point and guided assistants; remote updates and parameter sync.
• Secure by design: Speedwire encrypted communication and Trusted Platform Module (TPM) for hardened security.
• Rich I/O on board: 10 digital inputs + fast stop, 5 relay outputs, 4 analogue in, 4 analogue out, 2× PT100 temperature.
• Open protocols: Modbus TCP/RTU with SunSpec support; integrates third-party meters and SCADA.
• Insight & reporting: Sunny Portal analytics, alerts, automated reports and long-term set-point logging.

Key applications

• Zero-export and dynamic export limitation at the point of interconnection.
• Active/reactive power control (P, Q, cos φ, P(f), Q(U), Q(P)).
• Battery optimisation (time-of-use, self-consumption, peak-shaving) and EV charging visibility.
• Clustered sites using superordinate/subordinate Data Manager topology.

Technical highlights

• Interfaces: 2× RS-485 (Modbus RTU), 3× Ethernet (10/100 Mbit/s; 2× switched system LAN + 1× WAN), Wi-Fi 2.4 GHz AP.
• I/O: 10× digital IN + 1× fast stop; 5× multifunction relay (30 V DC, 1 A); 4× analogue IN (0–20 mA); 4× analogue OUT (0–20 mA); 2× PT100 temperature IN.
• Power: 10–30 V DC supply, typical 8 W (external PSU).
• Environment: –20 °C to +60 °C; 5–95% RH (non-condensing); up to 3,000–3,500 m a.s.l.; IP20; indoor, DIN rail or wall mount.
• Device capacity: Up to 50 inverters/meters/sensors/EV points; Speedwire device updates via SMA Update Portal.
• Data & updates: Local set-point storage (long-term), hourly/daily FTP push, OTA self-update and Speedwire device updates.

Compatibility

• SMA Sunny Tripower, Sunny Tripower CORE/CORE2, Sunny Tripower X, Sunny Tripower Storage X, Sunny Island, Sunny Boy Storage and more.
• SunSpec-compatible third-party meters and devices via Modbus TCP/RTU.
• Sunny Portal powered by ennexOS, SMA 360° App, SMA Energy App (supported features may vary by device).
