Keep It up, Your are excellent at explaining the individual critical components of the entire Solar System. Well Done. Please keep making more videos

How do I hookup my 2 series strings to those switches? Do I ignore the 3rd pole?

[@Atgul-z6o]

Good video, still unsure if I need to have my neutral switched at the AC disconnect coming out of my inverter. It can’t hurt if I do but that’s a more expensive switch.

Lot of the solar coding requires on a DC setup side to have the neutral (negative)wire hooked up to the switch now. You can't wire nut it or buss bar it

HOWdy E-UME, Thanks COOP ...

Thanks very much, Drew. But at 5:06 you are shown holding a solar DC disconnect box but unless I missed it, you never discuss that box in this video. Is it that perhaps due to editing it's covered in another?

He begins that discussion at 4:35.

@@k311ydcart3r indeed he may, but I don't see that addressing what I'd raised. Can you help us by offering why you do?
