SMA Data Manager M powered by ennexOS - Now with simplified commissioning and O&M support

Get the most out of energy

In combination with the new Sunny Portal powered by ennexOS, the Data Manager M optimizes communication, monitoring and control of PV systems with up to 50 SMA devices. Based on the new IoT platform for energy management, ennexOS from SMA, the Data Manager M not only replaces the SMA Cluster Controller, but its expandability also means that it is already well-equipped to handle the new business models of the energy market of the future. For example, it is the ideal professional system interface for electric utility companies, service technicians and PV system operators.

Particularly impressive is its innovative and highly efficient user interface, which has been standardized for both Data Manager M and the new Sunny Portal powered by ennexOS. A range of intuitive assistance functions for the Data Manager M, inverters and Sunny Portal powered by ennexOS significantly reduce the amount of time involved in commissioning and parameterization.

The basic scope of functions and interfaces offered by the new Data Manager M is coordinated with the associated functions in Sunny Portal powered by ennexOS and adapts to future requirements incrementally. Thanks to its modular design and systematic support of industrial standards such as Modbus/TCP, systems can be expanded to include additional components such as I/O systems or energy meters, from either SMA or other suppliers.

  4. FTP push
    System data is sent once a day via FTP push. The format is identical to the SMA Cluster Controller; configuration takes place in the Data Manager or remotely in the Sunny Portal

New functions for managing systems and devices

  1. Even more flexibility in incorporating external energy meters:
    SMA offers I/O systems from Moxa and Wago as accessories. The Elkor WattsOn Mark II has been added to the list of the energy meters preset in the system. In addition, we have maximum flexibility because any Modbus/TCP energy meter can be integrated. SMA Energy Meter and Janitza Power Analyser UMG 604 have been available since the release of ennexOS.
  2. Deleting devices in the EDMM
    Devices can now be deleted on the Data Manager under Configuration > Device management. Devices are then deactivated in the portal and are no longer displayed in lists or visualizations. The data of the deactivated devices can still be viewed in the Sunny Portal powered by ennexOS on the Analysis Pro page.
  3. Data migration from Cluster Controller systems
    If an SMA Cluster Controller is replaced with a Data Manager, the portal can transfer the energy and performance data of the devices and overall system from Sunny Portal in the system setup assistant.
    Transferring data from systems with other SMA loggers (e.g., Sunny WebBox or Sunny Home Manager) will be supported in future releases.

Expandable thanks to modular design - additional functions will be available since August 2018

* Current planning status. Changes possible!

Check in the settings of the router whether DHCP is enabled. If DHCP cannot be enabled, a static IP address must be assigned to the Data Manager. To do this, connect the Data Manager to a DHCP-capable router outside the PV system and carry out the commissioning. Assign a correct static IP address to the Data Manager (ask your grid administrator). Then connect the Data Manager to the router in the PV system. Now the Data Manager can be reached via the static IP address. Follow the installation assistant steps and make the settings appropriate for your system.

Depending on the web browser, the entry may be interpreted as a search entry. Enter "https://" before the access address of the Data Manager in the address bar of the web browser.

In order to save the self-signed certificate of the Data Manager in the web browser, it must initially be accepted as trustworthy in the web browser. After the Data Manager has been reset to the default settings, the web browser interprets this certificate as outdated or invalid. Delete the old certificate in the security settings of your web browser. Reconnect to the Data Manager and accept the newly offered certificate.

It is possible that the IP address of the I/O system cannot be determined. Check in the router's settings whether DHCP is enabled and, if necessary, enable DHCP. Ensure that the I/O system is set to DHCP. For this, all DIP switches on the I/O system must be set to ON (see the manufacturer's manual).

In order to use the I/O system with the Data Manager, the I/O system with its IP address must be disclosed in the Data Manager. To determine the IP address of the I/O system, proceed as follows:

1. Open the command line interpreter on a suitable end device and enter the command "arp-a".

  • A list of all interfaces with IP address, physical address and type is displayed.

2. The physical address indicates the associated IP address.

  • I/O systems by WAGO use physical addresses in the range 00-30-de.
  • I/O systems by Moxa use physical addresses in the range 00-90-E8.


The buffer capacitor of the Data Manager's real-time clock might have discharged due to being without voltage supply for a longer time period. Make sure that the Data Manager has access to a time server on the internet to obtain a current time.

No. Assign the user name and password and then stop the installation assistant. The original PV system data are still there and are adopted automatically.

This is not possible. However, system sections can be created and visualized in Sunny Portal powered by ennexOS.

Yes. To adjust the data transfer rate of the SMA Energy Meter, you have to log on to the user interface of the SMA Energy Meter with the user group Installer (see the SMA Energy Meter manual). The remote configuration of the SMA Energy Meter is not possible for safety reasons.

A few RS485 devices are currently not yet supported by the Data Manager:

  • SolTrk (control for PV tracking systems)
  • Windy Boy (wind power inverter)
  • Hydro Boy (fuel cell inverter)
  • Sunny SensorBox
  • Schoolmeterbox

This is possible in Sunny Portal powered by ennexOS. System sections and system groups can be created and visualized there.

Both the SMA Cluster Controller and Data Manager are data loggers. Parallel operation of both products is not advisable.

ClearType might be disabled. Activate Clear Type in your web browser.

Some Modbus devices may have been restarted due to a voltage drop. In the process, the Modbus devices received new, modified IP addresses from the DHCP router. This can happen if a MAC address has not been assigned in the DHCP router. The Modbus devices do not necessarily receive the same IP address.

Set up the MAC address connection in your DHCP router or extend the lease time.

If the IP address of a Modbus device had been changed, it must be recorded in the Installation Assistant of the Data Manager.

Ensure that the I/O system is set to DHCP or a valid IP address (see manual from manufacturer).

The I/O system must be configured as follows (from left to right):

  • 750-352: Fieldbus coupler/controller
  • 750-602: DC power supply (24 V)
  • 750-1414: 8 Digital inputs (24 V)
  • 750-1515: 8 Digital outputs (24 V)
  • 750-464: 2/4 Resistance inputs (2 x Pt100)
  • 750-455: 4 Analog inputs (4 to 20 mA)
  • 750-559: 4 Analog outputs (0 to 10 V)
  • 750-600: End clamp

The WAGO-I/O-SYSTEM 750 is suitable for connecting Pt100 temperature sensors with two, three or four wires. SMA recommends connecting Pt100 temperature sensors with two wires since the corresponding bus terminal 750-464 is preset to 2-channel measuring technology.

Ensure that for both I/O systems DHCP has been set or a valid IP address. Ensure that the mode of the analog inputs is adjusted for the ioLogik E1242 (see manufacturer manual).

IP address:

The IP addresses of the I/O systems from Moxa can be adjusted via the user interface or via the ioSearch program from Moxa.

Analog inputs ioLogik E1242:

The analog inputs of the ioLogik E1242 from Moxa are preset to 0 V to 10 V.

To be able to use the analog inputs of the ioLogik E1242 with the Data Manager, the analog inputs of the ioLogik E1242 must be set to 4 mA to 20 mA (see manufacturer manual).

The ioLogik E1260 from Moxa is suitable for the connection of Pt100 temperature sensors with two or three wires.
