Hey everybody!
I finally was able to produce the first part of my Balcony Solar Series on YouTube.
If you are interested in this topic, feel free to have a look and ask your questions. One of the upcoming parts will be about a self made zero injection function for the whole house. If you are interested in that too, subscribe and you dont miss it 
As always, video is in german voice but with many subtitles which was much work to do for you guys. Hope you enjoy!
Erik
