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.

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.

System sections can be implemented by using higher-level and lower-level system managers. In this process, all Data Managers (higher-level and lower-level) are displayed as one system in the Sunny Portal powered by ennexOS. In the Sunny Portal powered by ennexOS the system can be divided into system sections.

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 grid administrator to specify the exceptions for the firewall. When doing this, follow the information on the ports in these FAQs.

The buffer capacitor of the Data Manager's realtime 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. You can also assign the current time of a connected web browser to the Data Manager. In this case, the time is not synchronized cyclically with a time server. Over time, this causes inaccuracies (a few seconds per day).

To do this, several Data Managers M must be installed in the system. Each Data Manager M supports up to 50 devices At least one Data Manager M must be configured as the higher-level system manager. The other Data Managers M must be configured as lower-level system managers.

In Sunny Portal powered by ennexOS, each Data Manager M must be registered separately in the system. All Data Managers M are displayed together in the system. The device overview can show which of the Data Managers M each device is assigned to.

The system with the excess devices will be kept for the time being. If the system is extended or devices are replaced, the limitation of the number of devices becomes effective. In such cases, we recommend extending the system with a lower-level Data Manager. The total power of the system may not exceed 2.5 MVA (7.5 MVA for monitoring and open-loop control).

For this, establish a direct connection to the Data Manager via Wi-Fi and perform commissioning (see product manual). 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.

When the DHCP validity period expires, a new DHCP request is performed. In the process, it is possible that the Data Manager and connected devices are assigned a new IP address. We recommend using a dynamic host configuration protocol. This always assigns the same IP address to devices with a known MAC address.

Each Data Manager is initially assigned the static IP address 192.168.12.3. This address cannot be changed. This may cause conflicts in the network when the network class of the 192.168.12.xxx range is used. Avoid this network range.

In Sunny Portal powered by ennexOS, under Configuration > System properties > External access > Data communication, the frequency and amount of data to be transmitted can be specified in 3 levels (default is "high").

If the data transfer rate is below that of the standard LTE connection (e.g., due to used up data volume), all Data Manager services can no longer be guaranteed. This can affect the following services: FTP-Push, communication to Sunny Portal, updates, diagnostic data, SMA SPOT.

Every five minutes, the Data Manager L / SMA Power Plant Manager transmits the system data to the Sunny Portal powered by ennexOS. The expected data volume of 60 inverters is up to approx. 500 MB/month. The estimated data volume for 9 inverters is up to approx. 200 MB/month.

For Modbus devices, either static DHCP or static IP addresses are recommended so that the IP addresses do not change during operation. The static DHCP can be set in the router (the MAC address always receives the same DHCP address). A static IP address can be specified in the respective device (must not be in the router's DHCP address range).

You can connect suitable energy meters / power analyzers to the Data Manager by using the local grid. Furthermore, all energy meters / power analyzers that have a Modbus TCP interface can be connected (for a list of supported devices, refer to the Data Manager manual and the manufacturer declaration at www.SMA-Solar.com). The measured data are displayed in real time as a list view in the Data Manager. The data can be displayed with a delay as curves in the Sunny Portal powered by ennexOS.

No, that's currently not possible. Each device used can represent only one system device. Modbus TCP data concentrators that map, for example, several energy meters to different Modbus register ranges or unit IDs can only be used for a single system device.

Data concentrators that are connected via Modbus RTU and map multiple devices via different unit IDs could be used for this function. Currently, there are no known data concentrators that operate in this mode.

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. Make sure 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 or the "WAGO-I/O-SYSTEM 750 with SMA DATA MANAGER M" manual at www.SMA-Solar.com).

When the DHCP validity period expires, a new DHCP request is performed. In the process, it is possible a new IP address is assigned. For Modbus devices, either static DHCP or static IP addresses are recommended so that the IP addresses do not change during operation.

The WAGO I/O SYSTEM 750 is suitable for connecting Pt100 temperature sensors with 2, 3 or 4 con-ductors. SMA only supports connecting Pt100 temperature sensors with 2 conductors since the corresponding 750-464 bus terminal is preset to 2-channel measuring (see Fig. 1). Inputs that are not used must be bypassed (see Fig. 2).

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 connection has not been assigned in the DHCP router. So the Modbus devices do not necessarily receive the same IP address.

When a system is deleted in Sunny Portal powered by ennexOS, the associated Data Manager and any existing lower-level Data Managers must also be reset to default settings. Otherwise, these Data Managers cannot be registered in other systems.

The Data Manager typically requires static signals on the internal inputs (I/O system from Wago or Moxa). To be able to use pulse signals, preprocessing is necessary (e.g., by an additional mini control system). For more information, see the technical information "Conversion of Power Specifications via Pulse Signals" at www.SMA-Solar.com.

If the grid operator specifies an active power specification at the point of interconnection, this always refers to the measurement at the point of interconnection. Therefore, for pure feed-in systems, the operating mode "open-loop control" (without feedback of the actual value) is sufficient. For systems with self-consumption, the operating mode "closed-loop control" (with feedback of the actual value) should be used, since this converts excess PV energy into self-consumption and the power value at the point of interconnection still meets the grid operator's specification.

In pure feed-in systems and also in systems with self-consumption, the operating mode "closed-loop control" (with feedback of the measured values from the point of interconnection) should be selected. This way, the Data Manager accounts for and controls the influences of the line and, if applicable, of the transformer.

In systems with high self-consumption and a high reactive power demand (e.g., operation of electrical machines in commercial and industrial plants without an additional compensation system), the PV inverters might not be able to control the setpoints at the point of interconnection (reactive power value, cos phi value). For example, this can be operation of electrical machines in commercial and industrial plants without additional compensation equipment. In such systems, the PV inverters will generate almost only reactive power and hardly any active power. In such cases, the "open-loop control" operating mode is recommended.
