The Data Manager M is the perfect monitoring and control solution for decentralized large-scale PV power plants up to 2.5 MVA with up to 50 devices. Thanks to the RS485 and Ethernet interfaces as well as analog and digital input and output systems, users benefit from particularly versatile connection options. The Data Manager M is the professional system interface for electric utility companies, direct sellers, service technicians and PV system operators.
The Data Manager M and the new Sunny Portal powered by ennexOS are perfectly coordinated with each other. This not only makes it easier to monitor, analyze, parameterize and manage PV systems, but also helps save time and money.
Whether for an entire portfolio, system groups, systems, PV system sections or individual devices, you will find the relevant information for the various user roles on the dashboards in a clearly structured format—at every level
Standard pages for monitoring, analysis and parameterization allow you to work efficiently and help you save time managing your systems.
The preconfigured MOXA and Wago I/O systems available from SMA are perfectly coordinated with the new IoT energy management platform ennexOS and can be easily integrated into a system. Thanks to its high level of flexibility, the system can meet changing customer requirements at any time, for example, if there are any changes in legal or normative requirements.
The Data Manager M Lite monitors, controls and regulates up to five devices in one application with up to 30 kVA. It therefore meets all current requirements of grid operators for active and reactive power control. We are continuously developing software expansion options tailored to customer needs. Automatic firmware updates keep the device up to date with the latest safety and performance standards.
With intelligent charging technology from SMA, e-mobility makes sense both environmentally and economically. The Data Manager M Lite ensures that charging electric vehicles takes priority when the PV system is producing enough solar energy or the grid current is particularly favorable.
Combined with an EEBUS-compatible charging station, the SMA Data Manager M Lite automatically schedules the charging process for electric vehicles according to the individual requirements of its users. With the Energy App and the Sunny Portal for system monitoring, you can keep constant track of your energy budget and uncover additional energy saving potential.

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.
For this, establish a direct connection to the Data Manager via WLAN and perform commissioning (see product manual). Assign a correct static IP address to the Data Manager (ask your grid administrator).
Connect the Data Manager to a DHCP-capable router outside the 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".
2. The physical address indicates the associated IP address.
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:
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.
Assign only static IP addresses for Modbus devices if possible.
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):
The WAGO-I/O-SYSTEM 750 is suitable for connecting Pt100 temperature sensors with two, three or four wires. SMA only supports the connection of Pt100 temperature sensors with two wires since the corresponding bus terminal 750-464 is preset to 2-channel measuring technology (see Figure 1). Inputs that are not used must be shorted (see Figure 2).
For shorted measuring channels, the value -200 °C is shown in the user interface of the Data Manager. No values are shown when sensors are defective or cables broken.
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).
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.
When connecting Pt100 temperature sensors with three wires, the measurements are more accurate, especially for long conductor lengths.
When connecting 2-wire Pt100 temperature sensors, SMA recommends connecting a 3-core shielded cable to the Moxa ioLogik E1260. Lead the third conductor close to the Pt100 temperature sensors and connect it to one of the two Pt100 connectors. Connect the cable shield on one side to the grounding conductor on the Moxa ioLogik E1260. The Moxa ioLogik E1260 itself does not have a connection for a grounding conductor. That is why the grounding conductor of the switch cabinet should be used (there should be a grounding conductor on the DIN rail or the enclosure of the switch cabinet).
In case of inaccurate measured values, the inputs of the ioLogik E1260 from Moxa can be individually calibrated via the user interface (see manufacturer manual).
You can use the power supply unit of the Sunny WebBox, SMA Cluster Controller, SMA Com Gateway or the SMA Inverter Manager. You can also use all power supply units that meet the specifications of the datasheet and the Data Manager manual.
No. To be able to detect new devices, the installation assistant of the Data Manager must be started. Devices with different passwords can also be detected in the installation assistant.
No. Only the master data is currently transmitted. For release 2018, it is also planned to allow for transmission of slave data.
For technical reasons, only in-house certificates will be used. Certificates that could be replaced by an intercepting proxy server cannot be verified. Please contact your network administrator to specify the exceptions for the firewall.
You can connect temperature sensors, solar irradiation sensors, and anemometers to a suitable I/O system. The measured data are displayed in real time as a list view in the Data Manager. Furthermore, the data can be displayed with a delay in wave form in the Sunny Portal powered by ennexOS.
The linearization of the temperature sensors' data takes place in the I/O system. In the case of solar irradiation sensors and anemometers, however, the sensor itself must be designed for a linearization of the data.
The following table shows the connection possibilities of the sensors to the I/O systems:
|Temperature||Ambient temperature in °C
Cell temperature in °C
|1 sensor (2 conductors)
1 sensor (2 conductors)
|1 sensor (2 or 3 conductors)
1 sensor (2 or 3 conductors)
|Irradiation||Solar irradiation in W/m²||4 mA to 20 mA||1 sensor||1 sensor||-|
|Wind||Wind speed in m/s||4 mA to 20 mA||1 sensor||1 sensor||-|
You can connect suitable energy meters with the Data Manager using the local network. Furthermore, all energy meters can be connected that have a Modbus TCP interface. The measured data are displayed in real time as a list view in the Data Manager. Furthermore, the data can be displayed with a delay in wave form in the Sunny Portal powered by ennexOS.

In order to add new devices to the Data Manager, the devices have to be in operation and located in the local network. Make the following settings on the user interface of the Data Manager:
For this, several Data Managers M must be installed in the system. The Data Manager M supports up to 50 devices.
In order to manage 70 devices, for example, 2 Data Managers M must be installed in the system. Make sure the designation of the devices is unique. This can be helpful by making later assignment of the devices easier. For the commissioning of the first Data Manager M, 50 of the 70 recorded devices in total must be selected. For the commissioning of the second Data Manager M, the remaining 20 devices must be selected.
In order to be able to manage all 70 devices in one system, the devices can be compiled into one system group in the Sunny Portal powered by ennexOS.
To set up zero export, there must be an appropriate energy meter installed at the grid-connection point. Make the following settings on the user interface of the Data Manager:
1. Select the menu item Grid management service in the menu Configuration.
2. Select Active power.
3. Confirm every step with [Continue]
4. Select the operating mode Closed-loop control.
5. Select the signal source Manual control.
6. Enter the value 0 in the field Active power setpoint
7. Enter the value 1 in the field Time interval.
8. Enter the value 100 in the field Active power gradient.
9. In the field Total system power, enter the desired value.
10. Select [Save].
No further settings are necessary. Now you can find a new widget for active power limitation on the system’s dashboard.
