Data Manager

Supported devices: SMA Data Manager M (EDMM-10), M Lite (EDMM-10.A), L (EDML-10)

The SMA Data Manager aggregates the inverters of a plant behind a single connection. Our EMS reads the plant's combined production and applies plant-level active-power curtailment through the Data Manager instead of addressing each inverter individually.

Supported devices

  • SMA Data Manager M (EDMM-10)
  • SMA Data Manager M Lite (EDMM-10.A)
  • SMA Data Manager L (EDML-10)

EMS functionality

  • Monitoring of aggregated PV production across all connected inverters
  • Plant-level active-power curtailment where supported (negative-price capping, fixed injection limit, zero injection)
  • Integration of PV production into broader energy-management strategies

Configuration

  1. Connect your computer to the same LAN as the SMA Data Manager and open its IP address in a browser.
  2. Log in as Installer.
  3. Enable the Modbus TCP server (port 502) so the EMS can read the plant and send setpoints.
  4. Make sure Modbus and grid-management mode are enabled on the aggregated inverters as well, otherwise curtailment cannot take effect.

The Data Manager reports the combined production and forwards the EMS's active-power limit to its inverters. For inverters connected directly, without a Data Manager, see Sunny Boy / Sunny Tripower.

Enter the plant's installed PV capacity when adding the device. The Data Manager applies the EMS limit as a percentage of that capacity, so an incorrect value leads to incorrect curtailment. The same capacity has to be entered on the Data Manager itself, see Reactive power control (Data Manager).

For reactive power, which is configured separately and has its own pitfalls, see Reactive power control (Data Manager).
