Hi everyone

I'm currently in the process of going off grid.

I have a few concerns about the earthing and the earth/neutral bond.

My panels are earthed directly to a copper earth rod in the ground.

1) Can I still use Eskom's earthing rod going into my DB as this earth is still the best you will get? If not, what must I do?

Currently all my ac earths are connected to earth rod in main DB.

2)Can I feed a 6mm wire from main DB earth rod to my inverter?

3) Where and how will I do my permanent earth/neutral bond once the prepaid meter is removed and fuses pulled from mini sub?

Oh! Please try and explain in away that a stupid diy guy lime myself can understand.

I almost forgot to ask. What is the standard if you want to route your solar panel wiring through the roof and then out underneath tiles down outside wall to earth rod?

Nothing that Eskom provides is the best. Typically the neutral to earth connection at your supply point should be competent. If you want to have multiple earth rods, I would connect them all.

If your inverter will be your main supply, I would connect earth and neutral inside the inverter. Earth leakage units downstream require this but units upstream will trip.
