I'm not a specialist, so excuse my question.
Let's say the Panels are far from the inverter 100m and at some point (weather, temperature .. i dunno) the electric potential of the ground is far different under the inverter that it is under the panels (even if it's for a small amount of time .. a lightning strike)... if there is only one rod under the inverter.. and the metal parts of the panels are connected to this ground rod. Would that mean that touching the panels would be dangerous cause the potential delta is high ? Dunno if i'm clear ... :D
Or does this simply never happend ..?
