Release Notes for Partners

This website contains an overview of all software updates published by sonnen for all sonnenBatteries for generation 8 or higher. This page is only designed for our partners, installers, and service partners. If you intend to share release notes with your customers please refer to this page here.

Note:

Please note that the sonnenBatterie will automatically download and install any new software updates if you are connected to the Internet. No further action is necessary on your part. sonnen may delay the download and update of specific software releases up to 14 days.

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 the system is offline for more than 8 weeks, please establish a connection to the Internet so that your system can download and install available updates. If you only want to download and install mandatory updates, please contact our customer service.

Software version: 1.14.5

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

Features:

[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).
More information on battery maintenance can be found in our blog article: https://sonnengroup.com/battery-maintenance/

BUGFIX: sonnenModule 3: Solved an issue that the serial number of the sonnenModule 3 was not shown in the Dashboard.
BUGFIX: sonnenBatterie hybrid: Previously, some systems could incorrectly limit the maximum charging power to 1200W in certain operating conditions.
BUGFIX: Time of Use: UTC (Universal Time Coordinated) was previously used as the internal system time for this function. This led to problems in the Time of Use function because UTC does not support daylight saving time (DST). Therefore, activating and deactivating battery charging was previously shifted by one hour during DST season.
BUGFIX: sonnenBatterie 10 performance did not show the correct eclipse color after a startup of the sB10p without internet connection. We now show the correct eclipse state, based on a faster detection of missing internet connection.
BUGFIX: sonnenProtect 4000 & 8000: In some cases, the LED which indicates overload conditions in offgrid mode remains on after pushing the protect button and bringing the sonnenProtect back in service. We now show the correct indication of overload condition by sonnenProtect-LED.
BUGFIX: sonnenModule 3 and sonnenModule 4: There were a few systems that did not perform the mandatory full charge every 30 days. This has now been fixed.
BUGFIX: Commissioning Assistant: Login problems in the commissioning assistant solved, as now the Commissioning Assistant will only be available, once the API is ready. 
BUGFIX: Commissioning Assistant: More than 6 measurement channels led to wrong measurement data transmission. Therefore, the max. amount of measurement channels which can be activated has been limited to 6 channels. (=max. 3 power meters)
BUGFIX: sonnenBatterie 8 or higher:  We have fixed sending internally incomplete data measurements by an improved system performance. Systems are running now more stable.
