Cheap 4-life
My body is 2.63 trillion volts, .07v per cell
Thanks in advance for your assistance.
When I installed my roof mount array (metal roof) I had the understanding that the array should be grounded to its own ground rod. I understand now that might not be correct.
Now I’m planning to add an outdoor pv safety disconnect switch and a dc surge protector. I do not have a ground wire running with the pv wires. The pv wires are in plastic conduit in the attic space.
How do I ground the safety disconnect and the dc surge protector?
I was hoping to mount the dc surge protector directly onto the pv disconnect switch. The combiner for the pv is inside the house. I want to put the pv disconnect after the combiner on the outside of the house.
Do I have to disconnect the array from it’s ground rod and run a ground wire along with the pv wires then into the pv disconnect. I was thinking that I don’t want to bring the dc surge/lightning into the attic on the ground wire. I guess I could mount the dc surge protector in the soffit instead of on the safety disconnect. That way surges are stoped before entering the house..
Thoughts?
Additional info. I am connected to the grid that also has a ground rod for the main panel
