I have solar panels on the roof (ungrounded) and an ATS to switch between solar (ungrounded) and grid power. (grounded)

EDIT : Sorry, my question wasn't clear enough, I'm talking about AC. My questions are :

1- can i connect cable number 1 and 2 ? (1 is connected to a ground rod and 2 is the ground wire running in the house)

2 - Can i put copper wires around my solar panels / inverter box and ground them by connecting them to the grid power ground wire too ? (wire number 1)

NEW EDIT : I should add too that I have some appliances connected directly to the grid power too. (And its ground wire 1.) Can they interfere or something ? Aka green wires here are just a cord connected to an outlet from the grid.

    Usually grid power is AC, and solar cells are always DC. I would expect that whatever sort of inverter you're using would deal with the grounding issues. – TimWescott Jun 9 '20 at 19:53

    What do you mean when you say "ground." Your question is kind of vague and because of that you are likely to get answers that are not right. I very strongly suggest that you simply hire an electrician or spend some time studying the electrical code applicable where you live. Grounding is surprisingly complicated. – mkeith Jun 9 '20 at 20:05

    I live in France 220v, what i call no ground is : just 2 wires connected instead of the 3 from the "wire pack". (Yellow not connected to anything) – bob dylan Jun 9 '20 at 20:09

    In the US many especially newer mounting systems for solar panels (rack systems) are designed and approved to electrically bond the panel frames and rack together electrically. But you still need to electrically bond your rack system to the grid green wire ground. You may also need to drive a ground rod depending on local code and inspector bias/point of view. As far as "grounding" the negative or positive wires for your PV string, you need to check the inverter instructions. I believe negative ground is most common but not universal. Like I said it is complicated. – mkeith Jun 9 '20 at 20:10

    @mkeith So... if i connect my solar ground wire to the ground wire of the grid (that is connected to a ground rod), ... something dangerous can happen ? – bob dylan Jun 9 '20 at 20:22
