Expansion of the Modbus functions

  • Output of further battery values via Modbus
    The following battery values can now be output via Modbus:
    • Average state of charge of several battery inverters in [%]
    • Current total charging power of all battery inverters in [W]
    • Current total discharging power of all battery inverters in [W]
    • Total charging power of all battery inverters in [W]
    • Total discharging power of all battery inverters in [W]
  • Permanent implementation of other Modbus profiles
    The following devices have been added to the list of Modbus profiles that have already been permanently integrated:
    • Siemens PAC 2200 (Modbus/TCP meter with MID certification)
    This allows users to integrate the device into the PV system more easily as the Modbus profiles that have already been saved ensure that the required measured values will be queried reliably.
  • Import and export of Modbus profiles
    Thanks to Modbus, a wide variety of devices, such as inverters, energy meters or sensors, can be easily connected to the SMA Data Manager M. The firmware release 1.8 now makes it possible to export and import the generated Modbus profiles on the SMA Data Manager M. This leads to a reduction in the time required for commissioning devices of the same type.

Implementation of various communication profiles

  • To allow for an optimum overview of the PV system, data are regularly transmitted from the SMA Data Manager M to the Sunny Portal. When connected via a mobile network, the amount of data can exceed the selected data tariff rates.
    For greater flexibility, there will be three different communication profiles to choose from. These profiles ca be activated in the Sunny Portal.

Expanding the grid management services

  • Output of cos (phi) via Modbus
    Values for cos (phi) can now be output via Modbus. This includes both the obtained default values and the currently measured cos (phi) value at the point of interconnection. For this, a meter at the point of interconnection is imperative.
  • Active power setpoints via external digital inputs
    Default active power values can now also be processed via external digital inputs for example, via the Wago 750 Bundle or Moxa ioLogic.

Update February 2020

Extended support of connected devices

  • Threshold based toggle of digital outputs
    From now on it is possible to toggle digital outputs based on active and reactive power level of the pv plant. If there is an energy excess a digital signal can be sent to an electric load to switch on for example a heating rod or a heat pump. Hereby irreversibilities by external power curtailment setpoints can be reduced and the produced energy can be used more efficient.
    Following setpoints or values can be used to toggle the digital outputs:
    • Alarm in case of warning or error
    • Alarm in case of error
    • System active power
    • System reactive power
    • System active power at grid-connection point
    • System reactive power at grid-connection point
    • Setpoint of active power limitation
    • Reactive power setpoint
  • Extended possibility to connect sensors
    To be able to connect sensor devices like weather stations more easy the range of connectable devices was extended by the device type „Sensor Device“. Hereby manually created modbus profiles can be added to connect for example the weather station PVMet 200 from Rainwise. The measuring data is availble locally on the Data Manager M as life data and in the Sunny Portal powered by ennexOS as data in the Analizing Tool Pro for further analyzing. Also connection of sensors to display a filling level (level in percent value) is possible by using the new Modbus device type. This measured data is currently only available locally on the Data Manager M.
  • Connection of Danfoss TLX and FLX pv inverters
    By implementing EtherLynx and protocol it is now possible to connect Danfoss TLX and FLX inverters to the SMA Data Manager M via Ethernet wiring. Measured Data can be sent to the Sunny Portal powered by ennesOS via the SMA Data Manager M. The other way round open loop and close loop control of the inverters is also possible now.
  • Fix implementation of further Modbus profiles
    The list of already fix intefgrated Modbus profiles was extended by following devices:
    • PQ-Plus UMD-705 ( 3-phase grid analyzer)
    • Rainwise PVMet 200 (weather station)
    Hereby the named devices can be connected to the SMA Data Manager M more easy. The fix added Modbus profiles guarantee a reliable promt of the requested measurement data.

Extension of grid management services

  • Support of reactive power setpoints via external digital inputs
    Now reactive power setpoints via external digital inputs (e.g. Wago 750 Bundle or MOXA ioLogik E1242) can be handled. Hereby it is possible to fullfill the requirements of the grid operstors more flexible. A separated installation of the SMA Data Manager M from the external I/O devices is also more easy now.

Update November 2019

Advanced support for connected devices

  • Expansion of the Inverter Manager integration
    • In addition to the already supported STPS 60, this release allows SMA inverter types STP 60 and SHP 75 to be connected to the SMA Data Manager M and the Sunny Portal powered by ennexOS. The devices connected to the Inverter Manager are aggregated and displayed as one device.
  • Central update of connected SMA inverters
    • Connected SMA inverters previously had to download available firmware updates individually. Now, the SMA Data Manager M simply downloads updates once centrally and distributes these throughout the PV system. This reduces the required data volume for systems that are connected via the mobile network to the Sunny Portal powered by ennexOS.

Advanced support for connected devices

  • Connection of inverters from other manufacturers
    • Implementing the Modbus Sunspec interface means that inverters from other manufacturers can now be monitored and managed using the EDMM and visualized in Sunny Portal. To support the different functions, more than 15 Sunspec data models have been integrated into the SMA Data Manager M. A connection can be established either via Modbus/TCP or Modbus/RTU.
  • Support for affordable Modbus/RTU energy meters
    • To expand the scope of supported devices here as well, Modbus/RTU energy meters can - in addition to the already supported Modbus/TCP energy meters - be connected to the SMA Data Manager M. The use of the generally more cost-effective Modbus/RTU energy meters is another way to optimize costs.
      The following devices are directly supported:
      • Measurlogic DTS-307
      • WattNode WNC-3Y XXX-MB
    • For the connection of additional energy meters, individual Modbus profiles can be created directly in the SMA Data Manager M.

Enhanced system security

  • Speedwire Encrypted Communication (SEC)
    • To enhance the security of our devices and, in turn, the entire PV system, secure encryption of the local SMA system network is now possible. The SMA Data Manager M automatically supports the activation of SEC in new systems.

Update May 2019

Grid management services

  • Supports digital inputs as well as analog inputs and outputs (through MOXA & WAGO I/O systems available from SMA) for the implementation of specifications regarding cos (φ), active and reactive power and the response from control values.
  • Reactive power: Open- and closed-loop control of cos (φ) already possible through constant setpoints. Specifications via Modbus and/or via analog inputs now also possible.
  • Active power: Specifications via Modbus and/or via analog inputs now also possible.
  • New MOXA I/O (ioLogik 1241) with four analog outputs. Soon also available directly from SMA.
    (SMA order number: eIO-E1241)
  • New Wago 750 I/O Bundle with four analog outputs (output signal 0–20 mA).
    (SMA order number: 115214-00.01)
  • Master/slave functionality: For the closed-loop control of large systems / systems with multiple devices, a master EDMM can control multiple subordinate slave EDMMs. Up to 50 devices or a maximum system size of 2.5 MW are supported (as before).

General

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.

System sections can be implemented with a master/slave system. In this process, all Data Managers M (mas-ters and slaves) 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.

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. This way you will receive the same system (installer) password.

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.

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.

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.

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

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 master. The other Data Managers M must be configured as slaves.

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.

Information:

  • The energy meter at the point of interconnection must be assigned to the Data Manager M in master mode.
  • Only a Data Manager M in master mode can perform controlling. The Data Managers M in slave mode are used in open-loop control mode.
  • I/O systems that are used to make control settings must be registered with the Data Manager M in master mode.
  • The Modbus interfaces must be activated on the Data Manager M in slave mode.
  • On the Data Manager M in master mode, the Data Managers M in slave mode must be integrated as Modbus devices.
  • The device assignment must be unambiguous, otherwise the balance, power and yield values will not be displayed correctly.
  • The total power of the system may not exceed 2.5 MVA. For larger systems, a Data Manager L must be used in master mode.

Due to internal setup processes, the start of the user interface takes a little longer once during commissioning.

The following devices are supported and defined as a device:

  • PV inverter
  • Battery inverter
  • Energy meter
  • External I/O system
  • External sensor
  • Weather station
  • Charging station for electric vehicles

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 Data Manager in slave mode. The total power of the system may not exceed 2.5 MVA.

Communication

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.

Depending on the web browser, the entry may be interpreted as a search entry. In the address bar of the web browser, Enter "https://" before the access address of the Data Manager.

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. At the moment, the SMA Meteo Station can only be used with restrictions.

The following table shows the required data volume of two example systems:

System Profile Firmware-Version < 1.10.6.R

Since VPN connections often cause display errors and functional restrictions, contact your administrator.

If you use an Apache server, enable the option button AllowEncodedSlashes (see the information at httpd.apache.org/docs/2.4/en/mod/core.html.

Energy Meter

Yes. To adjust the data transfer rate of the SMA Energy Meter, you have to log in to the user interface of the SMA Energy Meter with the user group Installer (see the SMA Energy Meter manual). For safety reasons, remote configuration of the SMA Energy Meter is not possible.

In order to add new devices to the Data Manager, the devices have to be in operation and located in the local grid. Make the following settings on the user interface of the Data Manager:

  1. Select the menu item Device administration in the Configuration menu.
  2. Select the [+] button.
  3. Select Modbus devices and confirm with [Next].
  4. Enter the device data and confirm with [Next].
  5. Select the device and select [Save].
  6. Select the menu item Meter configuration in the Configuration menu.
  7. Select the new device as the grid feed-in meter and grid-supply meter.
  8. Select [Save].

You can connect suitable energy meters to the Data Manager by using the local grid. Furthermore, all energy meters that have a Modbus TCP interface can be connected. 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 following table shows the connection options of the energy meter:

Energy meter Configuration Interface SMA Energy Meter Janitza
Power Analyser UMG 604-PRO
Elkor
WattsOn-Mark II Precisi-on Energy Meter
Grid feed-in meter and grid-supply meter Power input in W Ethernet Speedwire Modbus TCP Modbus TCP
Power input in W Ethernet Speedwire Modbus TCP Modbus TCP

Current in A Ethernet Speedwire Modbus TCP Modbus TCP
Feed-in meter in Wh Ethernet Speedwire* Modbus TCP* Modbus TCP*
Grid-supply meter in Wh Ethernet Speedwire* Modbus TCP* Modbus TCP*

* Meter values at maximum since the commissioning date

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.

The SMA Energy Meter is connected to the grid operator at the point of transfer:

  • for low-voltage installations (e.g., according to VDE AR-N 4105), at the low-voltage point of common coupling
  • for medium-voltage installations (e.g., according to VDE AR-N 4110), on the medium-voltage side of the transformer (current and voltage converters must be connected on the medium-voltage side with the same wiring diagram)

Ext. I/O Systems

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).

In order to use the I/O system with the Data Manager, the I/O system must be registered with its IP address 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".
    1. A list of all interfaces with the IP address, physical address and type is displayed.
  2. The physical address indicates the associated IP address.
    1. I/O systems by WAGO use physical addresses in the range 00-30-de.
    2. I/O systems by Moxa use physical addresses in the range 00-90-E8.

Make sure that the I/O system is set to DHCP or a valid IP address (see the manufacturer's manual or the manual at www.SMA-Solar.de).

The I/O system must be configured as follows (from left to right):

  • 750-352: Fieldbus coupler/controller
  • 750-602: DC power supply (24 V)
  • 750-1414: 8 digital inputs (24 V)
  • 750-1515: 8 digital outputs (24 V)
  • 750-464: 2/4 resistance inputs (2 x Pt100)
  • 750-455: 4 analog inputs (4 to 20 mA)
  • 750-559: 4 analog outputs (0 to 10 V)
  • 750-600: End clamp
WAGO-I/O-SYSTEM 750

The WAGO I/O SYSTEM 750 is suitable for connecting Pt100 temperature sensors with 2, 3 or 4 conductors. 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).

WAGO-I/O-SYSTEM 750

For bypassed 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 (see the manufacturer's manual or the manual at www.SMA-Solar.de).

Make sure that DHCP or a valid IP address has been set for both I/O systems. Make sure that the mode of the analog inputs is adjusted for the ioLogik E1242 (see the manufacturer's manual).

IP address:

The IP addresses of the I/O systems from Moxa can be adjusted via the user interface or via the ioSearch program from Moxa.

ioLogik E1242

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 the manufacturer's manual).

Moxa ioLogik E1260

Sensors

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.

The ioLogik E1260 from Moxa is suitable for the connection of Pt100 temperature sensors with 2 or 3 conductors.

3-conductor connection:

Moxa 3-conductor connection

When connecting Pt100 temperature sensors with 3 conductors, the measurements are more accurate, especially for long conductor lengths.

2-conductor connection:

Moxa 2-conductor connection

When connecting Pt100 temperature sensors with 2 conductors, SMA recommends connecting a 3-core shiel-ded cable to the ioLogik E1260 from Moxa. Lead the third conductor close to the Pt100 temperature sensors and connect it to one of the two Pt100 connections. Connect the cable shield on one side to the grounding conductor on the ioLogik E1260 from Moxa. 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 Moxa ioLogik E1260 can be individually calibrated via the user interface (see the manufacturer's manual).

Modbus Client

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 extend the lease time.

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.

The bytes in the product are set as follows and may need to be adjusted in the RS485 device:

  • 8-bit transmission, no parity
  • Baud rate: 1200, 9600 or 19200
  • Stop bits: 1

Modbus Server

Because the values in the sensor configuration are not assigned as system values.

Sunny Portal powered by ennexOS

  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 desired save location and confirm.
    1. The data are downloaded as a CSV file.

This is possible in Sunny Portal powered by ennexOS. System sections and system groups can be created and visualized there.

Only systems with a Sunny WebBox or an SMA Cluster Controller can be carried from the classic Sunny Portal over to Sunny Portal powered by ennexOS.

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

Grid Management Services

To set up zero export, there must be a suitable energy meter installed at the point of interconnection. Make the following settings on the user interface of the Data Manager:

  1. Select the menu item Grid management service in the Configuration menu.
  2. Select Active power.
    1. The installation assistant will open.
  3. Confirm every step with [Next].
  4. Select the operating mode Closed loop control.
  5. Select the signal source Manual control.
  6. In the field Active power setpoint, enter the value 0. To make sure that absolutely nothing is fed in, you can also enter a negative value here. If there is a negative value, however, this means that energy is always being drawn. In this case, the negative value should be at the height of the base consumption.
  7. In the field Time interval, enter the value 1.
  8. In the field Active power gradient, enter the value 100.
  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.

No, the Data Manager requires static signals on the internal digital inputs as well as on the external inputs (I/O system from Wago or Moxa). To be able to use pulse signals, preprocessing is necessary (e.g., by an additional Mini-PLC). For more information, see the technical information "Conversion of Power Specifications via Pulse Signals" at www.SMA-Solar.com.

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 opera-ting 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.

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.

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.

No, in such a case you can use a "virtual" utility grid meter in the Data Manager. This lets you specify an external cos phi setpoint. The specified setpoint will be different from the value that is set at the point of interconnection. An external closed-loop control by the grid operator is required.

Make the following settings on the user interface of the Data Manager:

  1. Enable the Modbus server.
  2. Configure a Modbus profile of the device type bidirectional meter with one power channel.
    1. For the channel designation Meter count of the grid-supply meter, select the register address 30513 and the scaling factor 0.
    2. For the channel designation Meter count of the feed-in meter, select the register address 30513 and the scaling factor 1.

First configure the Data Manager in slave mode. Then configure the Data Managers in master mode. Set up the system in Sunny Portal powered by ennexOS only after all Data Managers have been configured.

A Data Manager in slave mode can only be used in open-loop control. The master is responsible for the closed-loop control.

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.

SMA Speedwire Encrypted Communication (SEC)

When data communication between the Data Managers and inverters is encrypted, cyber security attacks on PV systems are much more difficult.

  • Inverters with SMA Speedwire from a production date > 2010 that are not connected via an SMA Com Gateway

  1. Use Sunny Explorer to reverse the system encryption.
  2. Remove the old device from the system.
  3. Include the new device in the system.
  4. Enable system encryption with a new password.
