Inverter on or off

I am new to this residential refrigerator thing. Our new sandpiper has a residential refrigerator and an inverter to run it when I am not on shore power. I understand how it works, my question is when I am plugged in at home ,(we let it run the fridge so we don't have to haul stuff in and out between trips) or at the campground should I be turning the inverter off? My PDI person told me that it was okay to just let it run. I have little faith in him as I knew he was wrong on some other items. It is a WFCO 1000 watt model if that matters.
Thanks for the help

I turn mine off, but was told the inverter “knows” when hooked To shore power and just passes through.

My fan stays on when I leave it on even with shore power. Kinda was driving me nuts so I shut it off. I would guess leaving it on is “wearing” it out as well.

I've checked mine out and the simplest answer would be: It depends on what you are comfortable with.

On our Sprinter, the inverter and shore power both feed into what would appear to be a "normal seeking" transfer unit. The "normal" on mine is shore power while the "alternate" is the battery powered inverter. Once shore power is applied to the transfer unit, it breaks the alternate feed and makes the normal feed. It does not turn the inverter off but the inverter is not powering anything either. If shore power is lost, the transfer unit supplies the refrigerator from the alternate source (inverter) until shore power is restored. IMHO, we will continue to leave the inverter turned on while onboard rather than risk losing the groceries while we are out on a day trip.

That is actually what I was hoping for. I feel the same about not losing groceries while we are gone. I just didnít want it to always run in the investor even when plugged in.
Thanks again.
