As a non professional armchair electrician- I offer a full refund for this free advice if it’s crap. The xantrex gets a/c in from the panel/breaker, and its a/c out goes to the outlets; this is the pass through when on shore/gennie. When inverting from battery, it’s sending a/c directly out to those outlets- it’s not sending back to the panel. Because the fridge does not benefit from inverting, it must be ‘upstream’ from the inverter. I’m not sure how that wiring is accomplished, maybe someone here knows.
