Hello, if you are a beginner in the field of solar energy, watch the video, you can benefit from it

hello everyone
A friend of mine contacted me about the installation of the work from the beginning so this video was posted.
In this video, we explain very important things
How to program the Voltronic inverter if it is three phase or Parallel
How to connect 48v batteries correctly even if the number is more than 20 batteries.
How is a three-phase or single-phase electric dashboard in general, with all protection systems?
I will upload a full video with details and explanation after completing the work also. Greetings to all of you and sorry for the length of the video, but the explanation is long and some friends need to know the details well......
