@packrat I have purchased Visio from Microsoft Visio 2021 Professional: Lifetime License for Windows | New Atlas at a price well worth it if you have a Windows setup. Keep an eye out for these deals.
I use proficad.
Its free for home use.
@janneman where do you get those component pictures into draw.io?
is there a URL that we could import from?
@janneman Would you mind sharing the drawio file for your setup.
My setup is nearly identical (including the 10m overspanning, the 3phase SolarEdge on AC side, the net attached meter etc) with very few exceptions (3 bateries instead of 2, no DC solar)
Would be great to have a clear diagram of it that I can hang in the meterkast
Not there any more
