I wired the light bulb between neutral and ground. I also added a 5A fuse in the line. When wired this way, the voltage from neutral to ground goes to about 50 mV. The voltage from Line to Neutral is 120V, as expected. The light bulb does not come on and the 5A fuse does not blow.
I do have continuity from the AC output ground to the grounding lug on the case of the inverter. There no internal connection (infinity ohms) from the AC output neutral to the AC output ground and the case grounding lug (when inverter is not powered).
Based on “Grounding Made Simpler” - I think this means I can wire up the Line, Ground, and Neutral wires to the breaker box. My breaker box is Neutral/Ground bonded. I also have a grounding lug on the outside case of the inverter. This one should also be connected to the grounding rod (essentially the ground inside the breaker box). Is that correct? My instruction manual says that “the ground terminal must be connected to the ground wire” and that for a fixed location install “connect the grounding terminal to earth”.
Edit: However, If I connect the AC output ground to the grounding bar in the main breaker box, and run a grounding wire from the inverter grounding lug back to ground (either to the grounding bar in the breaker box or to the grounding rod) this will create a ground loop. So, I should just leave the grounding lug disconnected?
Do I need to ground the battery negative? Where does it get grounded? I’m lost.
