SMA Data Manager M
powered by ennexOS

Function update June 2020
for EDMM-10 & EDMM-US-10

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).
