Hello,
Im setting up my off grid solar system and Im in the process of connecting the inverter to the main and existing fuse box of the house.
The AC is connected to earth. The AC neutral buss-bar is connected to the ground inside the main fuse box. The battery negative, solar panels, charge controller and inverter are all unearthed currently. My question is how do I connect these to ground? Do I connect all of those together and then take a cable into the AC fuse box buss bar? Or do I first disconnect AC neutral and ground before doing that to make it so called "floating"? Or do I connect to a separate grounding rod? What is a ground fault protector GFP and do I need it? is it the same as an earth leakage circuit breaker ELCB? I intend on using an ELCB for the AC.
