Quick run down how i have my inverter connected to the grid
Unfortunately i dont have any video of doing it but i made this video that quickly explains how its done in Sweden.
So basically what you need in Sweden to get it approved is:
2 stickers on the main cabinet
1 disconect switch that can be locked in some way.
Actually they dont even bother about how your inverter is tied to it nor if its all designed properly.
Though my system was approved by the electrician mounting the stickers as well just to make sure all was fine.
