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 S, 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, direct marketers, 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 step by step. 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.
Quick and easy
Reliable and convenient
Future-proof and flexible
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.

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.
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.
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.
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.
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.
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.
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.
The following table shows the connection possibilities of the energy meter:

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.
Compact system MOXA E1200 series for price-sensitive applications
Modular WAGO I/O system 750 series for more flexibility
Additional devices and protocols will be integrated on an ongoing basis via Modbus/TCP (e.g., Janitza Power Analyser UMG 604).
