Contrary to what we were told, we actually have a 120 VAC residential refrigerator. I was under the impression that this refrigerator would be powered by the solar panel on the roof when we were going down the road. Now that I know I have a 120 VAC refrigerator, I ought to have an inverter somewhere, right? There is, indeed, a little panel above the two fuse/breaker panels with an LED. It says, "LED on = inverter on. LED off = inverter off." Since the light is on, that ought to mean that the inverter is powering an outlet, right?

So where might this inverter be hidden? I'd also like to know if the inverter has a pass-thru function, so that when we're plugged into shore power the inverter outlet(s) are powered automatically without going through the inverter.
