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.
