PV Array Grounding/System Grounding
We all know that grounding seems to be a rather difficult area to address and determine proper technique.
Without dealing with every minute detail, in general, I am looking for opinions regarding the following...
Pole mounted array with negative lead grounded to ground rod next to pole.
Interior system componets (inverter, controller, etc.) bonded to battery negative lead and equipment ground with separete system ground rod at home structure.
Should the array ground rod be electrically connected (with cable lead of same gauge) to the other, system ground rod at house structure?
Should structure rod be eliminated?
Is individual rods ok?
Will two rods increase or decrease chances of lightning strike reaching componets?
My first inclination is that the rods should be connected, but I have read so many articles and "Code Corners" about grounding, i'm somewhat confused. Any ideas/suggestions?
