I was given a 300W inverter and I’m not entirely certain how to wire it up. The DC side has an earth ground terminal that that is bonded to the chassis of the inverter. The AC side has only 2 terminals, no ground. My plan is to use a GFCI receptacle to charge laptops and camera batteries. Does the ground on the DC side of the inverter need to be bonded to the battery negative? Does the ground wire for the 120V line get used? If I grounded the GFCI to the inverter would that protect both chassis? Both the GFCI and inverter chassis are isolated if I don’t. I didn’t know if bonding them, the GFCI would protect both, but I don’t think so.
