Reduxi with Sonnen Battery

Updated

Connect Reduxi with sonnen battery via Web API

 

1. Video tutorials

 

 

2. Connect sonnen battery local network

For effective communication, it is essential to establish a connection to the local network. Within this network, the Reduxi controller must also be connected. Connect the sonnen battery via LAN communication and enter the DNS of the battery: https://find-my.sonnen-batterie.com/

Note: Please follow the instructions on the link:

3. Web API and Token of sonnen battery 

Once the LAN connection is established and the IP of the Sonnen battery is obtained, addressing to Web API can be executed

The picture below displays how to obtain the API address and Token of the sonnen battery:

Please set the operating mode to Manual so that the Reduxi controller can take over control, as shown in the image below:

 

 

 

4. Connect Reduxi Controller to the sonnen battery

Once the internet connection between the battery and the Reduxi Controller is established, and communication to API is enabled, the user can begin adding the device to the Reduxi Controller.

 

4.1 Adding a device

Log in locally to the Reduxi configurator application on the controller and press the Add device button.

4.2 Select the device you would like to add

In the first step (basic settings), select the basic parameters of the device you want to add:

  • Device type: Hybrid inverter,
  • Type: Sonnen 
  • Name: Specify the name of the device.

4.3 Communication channel

The communication channel setup is designed to define connection parameters between the Reduxi Controller and the sonnen battery.

Insert API IP and token obtained from point 3. Web API and Token of Sonnen battery

4.5 Advanced Settings

The advanced setting is arbitrary and depends on the specific needs of the location where the Reduxi controller is installed. After finishing all the advanced settings, press the "Done" button on the lower right side.

5. Last measurements

After successfully establishing communication with the newly added device, its values ​can be checked under Devices/Sonnen battery in the Reduxi configurator as an additional test.

For advanced battery control, integrate the device into the strategy of the Reduxi system. Under Devices/Sonnen battery in the Reduxi configurator, the control type must be set to AUTO so commands for strategy will affect the battery.

To achieve maximal flexibility and energy cost reduction with respect to dynamic price and dynamic tariffs please follow the instructions on how to define strategy at this link: Strategies for Reduxi controller.

After successfully adding the device, it can be monitored and controlled also via the Reduxi application.
