I have a caravan, that is completely off grid.
I am trying to understand how to safely earth my inverter, which has a ground terminal that the manual says needs to be grounded.
After the inverter I have a consumer unit, which has an earth bar.
I've seen other posts such as the following, that state the ground should be connected to the caravan chassis:
But my understanding is that the caravan chassis is insulated due to the tyres, doesn't this mean the caravan chassis is not a suitable grounding point?
Would I therefore need to buy an earth rod and connect the grounds to the earth rod instead?
