Change in SMA Device Communication: WLAN and Ethernet to Replace Bluetooth

From on April 7, 2017 in Category Technology with 8 Comments

In the future, SMA will equip all devices with WLAN and Ethernet communication–so called IP communication–by replacing the previous Bluetooth communication. Thus PV systems are extremely easy to integrate into existing home networks with an internet connection. Below we have provided information for you, including how you benefit.

 

1. What are the benefits of WLAN and Ethernet communication?

  • Easy PV system monitoring thanks to integrated Webconnect function
    The integrated Speedwire/Webconnect interface in all SMA inverters up to 12 kW is able to establish a link with Sunny Portal and Sunny Places via the PV system operator’s router. The PV system can thus go online without any additional costs for a data logger.
  • Use of standard components
    Optimization of PV system communication will make it possible to use standard components from electronics retail outlets (e.g., WLAN repeaters, WLAN/DLAN access points, WLAN wireless sockets, etc.). Not only will this help PV system operators save on system costs, but they can also extend their home network with components, such as a repeater.
  • Flexible use thanks to Modbus as a third-party interface
    With the factory-installed open Modbus TCP interface, data loggers from other providers can also be flexibly integrated. This allows operators to save even more money because an additional communication interface (e.g., RS485) is no longer necessary to connect to SMA systems.

 

2. What has to be considered when planning a PV system?

System setup without data logger for PV systems with SMA inverters up to 12 kW

  • The Sunny Boy 1.5/2.5 and 3.0/5.0 inverters are connected to the router using the integrated Webconnect interface via WLAN or Ethernet cable, which means that they are integrated into PV system monitoring.
  • In the future, the Sunny Boy 3.0/5.0TL-21 and Sunny Tripower XY-20 models will have an Ethernet interface only and must therefore be connected to the router with wires.

System setup with the Sunny Home Manager 2.0 for PV systems with intelligent energy management

The Sunny Home Manager 2.0 is connected to the router via the Ethernet cable. Compatible loads and WLAN SMA radio-controlled sockets can be integrated into the system using the router. Further information on Sunny Home Manager 2.0 can be found here.

 

3. How can I identify SMA inverters with Ethernet communication?

The Sunny Boy TL-21 and Sunny Tripower TL-20 inverters will no longer have Bluetooth communication capability. However, they will still be fitted with Ethernet communication.

These devices are easily identifiable by the “ETHERNET ONLY” written on both the inverter and box, and by the yellow label on the inverters, which ensures rapid identification and smooth processes.

    Hi,
    Is there a http command to read the actual power or max power.
    For example, so I can switch devices
    Kind regards
    Ludo

      Hello Ludo,
      it depends on the inverter. Most of the current inverters from SMA can be read up via ModBus.

      You can get more information on our website http://www.SMA.de

      Kind regards, Jennifer

        Hello Jennifer,
        I have SMA 3600 21 TL.
        I want to use the http commands for my domotica system Loxone.
        It can be programmed with a “virtual http command”. Like: http://Ipadres:port/cgi-bin/image.jpg?size=1280×800?quality=90/
        That is what I looking for.
        Do you any manual.
        Kind regards.

    Are all of these changes effective immediately with purchase orders directly placed through SMA offices? I plan to buy inverters soon. The sunny design web still recommends older products and connection configurations.

    Is there a way of converting older Sunnyboy inverters that use Bluetooth to WiFi?

      Hi Peter,
      I am afraid there is no way of converting older inverter that use Bluetooth to WiFi.
      Kind regards, Annika
