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).

(Data Manager M Lite, Data Manager M)

You can use the power supply unit of the Sunny WebBox, SMA Cluster Controller, SMA Com Gateway or the SMA Inverter Manager for the Data Manager M and Data Manager M Lite. You can generally use all power supply units that meet the specifications of the datasheet and the Data Manager manual for all Data Manager devices.

(Data Manager M Lite, Data Manager M, Data Manager L)

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

(Data Manager M Lite, Data Manager M, Data Manager L)

To do this, several Data Managers M units 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 units 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 units are displayed together in the system. The device overview shows which Data Manager M each device is assigned to.

Information:

• The energy meter at the point of interconnection must be assigned to the higher-level Data Manager M.

• Only a Data Manager M configured as a higher-level system manager can perform controlling. The Data Managers M that function as higher-level system managers are used in open-loop control mode.

• I/O systems that are used to make control settings must be registered with the higher-level Data Manager M.

• On lower-level Data Managers M, the Modbus interfaces must be activated.

• On the higher-level Data Manager M, the lower-level Data Managers M must be integrated as Modbus devices.

• The device assignment must be unambiguous, otherwise the balance, power and yield values will not be display correctly.

• The total power of the system must not exceed 2.5 MVA. For larger systems, a Data Manager L must be used as the higher-level system manager.

• If the Data Manager M is used only for monitoring and open-loop control (without grid man-agement services), the nominal system power can be up to 7.5 MVA.

During commissioning, the Sunny Portal powered by ennexOS undergoes internal setup processes, which can cause a slight delay in loading the home page. This only occurs once during the initial setup. 

(Data Manager M Lite, Data Manager M)

The following devices are supported and defined as a device:

• PV inverter
• Battery inverter
• Energy meter / power analyzer
• External I/O system
• External, directly communicating sensor
• Weather station
• Charging station for electric vehicles
• Lower-level Data Manager
• SMA Hybrid Controller (only Data Manager L)

(Data Manager M Lite, Data Manager M, Data Manager L)

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).

In the settings of the router, check whether DHCP is enabled. If no DHCP can be enabled, a static IP address must be assigned to the Data Manager.

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).

or

Connect the Data Manager to a DHCP-capable router outside the system and perform 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.

(Data Manager M Lite, Data Manager M, Data Manager L)

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.

(Data Manager M Lite, Data Manager M, Data Manager L)

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 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.

All compatible RS485 devices connected to an SMA Com Gateway can be used with the Data Manager. When you do this, observe the restrictions listed in the FAQ section "Grid management services".

(Data Manager M Lite, Data Manager M)

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").

The following table shows the required data volume of two example systems (with the exception of updates, Webconnect, FTP-Push, 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.

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.

(Data Manager L)

If Field Data Management is activated, a higher data volume of approximately 200-600 MB/day can be expected. Very detailed information is transmitted using a high data rate. An Internet flat rate with an upload rate of at least 1 Mbit/s is recommended. If a firmware update is downloaded via the Remote Service, this is approximately 150 MB per update file.

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.

Data Manager M Lite, Data Manager M, Data Manager L

Exactly one energy meter is supported at the point of interconnection. This is used both for monitoring and energy balance and for open-loop control / closed-loop control at the point of interconnection.

(Data Manager M Lite, Data Manager M, Data Manager L)

The energy meter / power analyzer is connected to the grid operator at the point of interconnection:

• For low voltage (residential) installations install at the point of interconnection.

• For medium-voltage (commercial) installation on the medium-voltage installations install at the point of interconnection.

(Data Manager M Lite, Data Manager M, Data Manager L)

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.

(Data Manager M Lite, Data Manager M, Data Manager L)

SMA Data Manager M supports weather station devices via Modbus RTU (PVMet 200).

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 as curves 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.

For sensor connection options, see the technical information "SMA DATA MANAGER / SUNNY PORTAL powered by ennexOS - Functions" at www.SMA-Solar.de.

(Data Manager M Lite, Data Manager M, Data Manager L)

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.

Set up the MAC address connection in your DHCP router or, if possible, extend the validity period of the DHCP to infinite.

If the IP address of a Modbus device has been changed, it must be entered in the installation assistant of the Data Manager.

Assign only static IP addresses for Modbus devices if possible.

A distinction must be made here between active and reactive power:

Active power

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.

Reactive power

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. Contact your local grid operator.

(Data Manager M Lite, Data Manager M, Data Manager L)

No, this is currently not possible. Active and reactive power measurement values are required for a complete closed-loop control and open-loop control. These are only provided by a power meter if it is possible to measure both the voltage and the current. 

(Data Manager M Lite, Data Manager M)

No, this is not possible. The Data Manager supports only one measuring device for the point of interconnection.

(Data Manager M Lite, Data Manager M)

This should be avoided, as this causes the active and reactive power values to not match the actual values. When this happens, both the transformer losses and its phase shift lead to a faulty measurement.

(Data Manager M Lite, Data Manager M)

First configure the lower-level Data Managers. Then configure the higher-level Data Managers. Set up the system in Sunny Portal powered by ennexOS only after all Data Managers have been configured.

(Data Manager M Lite, Data Manager M, Data Manager L)

A lower-level Data Manager can only be used in open-loop control. The higher-level Data Manager is responsible for the closed-loop control.

(Data Manager M Lite, Data Manager M, Data Manager L)

This communication is monitored with a fixed timeout of 10 seconds. If the communication fails, the device is displayed as being disrupted. If closed-loop control is active at the point of interconnection, the operating mode is switched to open-loop control. This means that the setpoints are transmitted to the inverters (without closed-loop control). As a result, an inverter will not recognize this disturbance as such, and its own fallback behavior will not be activated if there is a communication failure. The inverter continues to receive the specifications from the Data Manager.

(Data Manager M Lite, Data Manager M, Data Manager L)

Inverters connected via RS485 communicate via the SMA-specific protocol SMA Data1. It is also possible to transfer power specifications to the inverters. However, there are restrictions that affect systems that have such devices (regardless of whether these devices are connected directly to the Data Manager M via an SMA COM Gateway):

• Due to stability reasons, if there are SMA Data1 devices in the system, controlled operation (closed-loop control) is not possible. Only controlled operation (open-loop control) is possible. As a result, any possible self-consumption is not taken into account in the event of power reduction specified externally or at a constant level.
• However, if this is desired, the RS485 devices concerned must be replaced by devices that can communicate directly via Ethernet (SMA Speedwire or Modbus SunSpec).

If a reactive power setpoint is required in addition, there are also restrictions in this case:

• Not all SMA inverters are reactive power-capable (this applies in particular to SMA inverters launched on the market before 2007).
• If these inverters are reactive power-capable and a setpoint should be specified, the inverters must be connected directly to the Data Manager M. If the inverters are connected via an SMA COM Gateway, it cannot be ensured that the function is given for all reactive power-capable inverters.
• Here, too, only controlled (open-loop control) operation is possible.

We recommend resetting the feed-in power limitations set in the inverter so that the parameters "P-Limit" and "P-Max" are set identically to the maximum power of the respective inverter.

(Data Manager M Lite, Data Manager M)

Run the installation wizard for the grid management services. When doing this, check the values for the AC nominal system power and fallback values. Adjust the values to the AC nominal system power that may have changed.
