In case you missed it, the latest version of the SFK Venus OS driver is out and it supports virtual batteries in both series and parallel configurations. We have discovered that there are some phyton changes in Venus OS firmware 3.41 that can cause some parts of the driver not to function, so we are uploading 2 versions of the Beta driver: Venus OS 3.41 & Venus OS 3.30 and lower. Be sure to download the version that matches your firmware! To learn more, hop onto the driver download page: https://www.sunfunkits.com/content/3081/victron-cerbo-gx-driver
