I am trying to help out a engineer who doesen't have a whole lot of experience with photovoltaic systems. He is looking for a detail of how the racks are grounded. From what I understand from article 690, the there is one ground at the inverter, and everything is tied back to that ground, including the racks etc?
Any detail would be great, or a website, thanks for the help.
