Too many questions and too little facts, lots of giba gaba.

We talking TN-S earthing system. All electrical installation in our part of SA are suppose to be TN-S.

The question: is it a good idea to install and earth spike close to the inverter?

If you feel there should be an earth spike, then why not install it at the meter box and install a 16/25 mm earth wire?

We all understand that there is a huge issue with cable theft, which results in all sorts of dangerous situations, would it not be better to scrap the old TN-S method?

What are the consequences of the council converting your TN-S system into a TN-C or TN-C-S system?
