SMA Data Manager M

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).

or

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".

• 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.

Assign only static IP addresses for Modbus devices if possible.

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.

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:

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:

1. Select a system in the Sunny Portal powered by ennexOS.
2. Select the Analysis Pro menu item in the Analysis menu.
3. Select desired data points and time periods.
4. Select the Details button.
5. Select the Download button.
6. Select the save location and confirm.
   • The data are downloaded as a CSV file.

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.
