Release Notes

On this page you will find an overview of the software updates released by sonnen for sonnenBatteries from generation eco 8.0/hybrid 8.1. We are constantly developing the sonnenBatterie and regularly provide improvements and new features free of charge to you.

Important Note:

Please note that your new sonnenBatterie software downloads and installs are automated if you have an internet connection. No further action is required on your part. 

Also note that the eclipse is not illuminated during the software update and your system will not be available via the app or the web portal. To ensure that the update can be successfully installed, the storage system must not be switched off, restarted or disconnected from the internet during the update. We therefore ask you to wait at least 15 minutes before restarting your storage system or contacting our customer service if the eclipse is not illuminated.

If your system is offline for more than 8 weeks, please connect it to the internet, so that your system can download and install any available updates. If you only want to download and install mandatory updates, please contact your installer for technical support.

Software version: 1.15.6

Release date: November 4th, 2024
Installation mandatory: Yes

Changes:

• [sonnenCore+, sonnenEvo] The new inverter firmware v1.16 is available as a mandatory update in the Commissioning Assistant for split phase systems with all USA and Puerto Rico grid codes. This firmware version prevents the system from shut down in offgrid mode if high inrush currents are present in the backup case. In case of overload the system stops the backup operation and disconnects itself from the backup loads. The system initiates a sequence of maximum 3 retries to reconnect and recover from this state if the cause of overload is removed.
• [sonnenBatterie 10 and sonnenBatterie 10 performance(+) without sonnenProtect] With this software, a new ‘Automatic Standby’ mode is introduced to increase the system efficiency. While the system is not able to provide any energy to the household, the system will go to Automatic Standby mode to reduce the self-consumption of the storage system. During Automatic Standby the eclipse will reduce its brightness to 20%. Due to technical requirements this feature is not available for systems in VPP or installed with a sonnenProtect.

Software version: 1.14.5

Release date: August 19th, 2024
Installation mandatory: Yes

Changes:

• [All Products] With this software, we introduce a new feature called ‘Surplus Fullcharge’. When this feature is activated, and if the battery needs a full charge for battery care reasons, it will only charge from the PV generation to further optimise PV self-consumption. The battery will not draw any energy from the grid to cater the full charge. Be aware that the full charge will not be suspended until 100% State of Charge is reached. For the battery behaviour this means that the full charge can take significantly longer when this feature is enabled compared to full charge from grid. This feature can be enabled by the user from the Dashboard as shown below (disabled by default).
• [All Products] In some rare cases the sonnenBatterie was interfering with the detection of other connected devices in the local network. This issue is now fixed.
• [All Products] All systems are showing the correct local time zone in the Dashboard now.
• More information on battery maintenance can be found in our blog article: https://sonnengroup.com/battery-maintenance/

Changes: 

• If the feed-in limit is set to 100%, the "Weather forecast" function is no longer displayed on the dashboard. For systems that do not have a feed-in limit, the intelligent charging management function and therefore also the weather forecast is not required.
• If you operate several sonnenBatteries in a cascade, the devices are now no longer referred to as "Master" and "Slave,” but are called "Primary" and "Secondary".

Software version: 1.6.10

Available from: 28.09.2021
Installation mandatory: Yes

Restriction: for sonnenBatterie 10 performance, these changes will only come with version 1.6.18

Changes:

• For systems with sonnenModule 3: If the battery has not been fully charged for 15 consecutive days, a full charge from the grid is carried out for battery maintenance. Previously, this was only triggered after 30 days, but for longevity reasons and in preparation for the next winter, this has now been adjusted. Furthermore, it has been improved so that the full charges for battery maintenance are reliably carried out regularly.
• After an internet connection or a general power failure, the Eclipse of the sonnenBatterie would pulsate Orange for a longer period. This has been improved with the new version.
• The issue revolving around incorrect values being displayed in the portal during emergency power operation has now been resolved.
• No software update can take place during emergency power operations. This prevents the sonnenBatterie from switching off after the update.

Available from: 27.04.2021
Installation mandatory: Yes

Changes: 

• sonnenBatteries with a display received an update of the display software. See "Display Version: 3" below. Furthermore, the textual instructions for the necessary calibration of the display after the update have been improved.

Software version: 1.5.7

Available from: 27.04.2021
Installation obligatory: No

Changes: 

• The control of the internal fan of the sonnenBatterie 10 performance has been optimised. It now switches on less frequently.
