Magic Chef Residential Refrigerators

Depends somewhat on what inverter/charger you have.

If you have one with a built in transfer switch, just "do it". Yes, it would be slightly better electrically to switch with no load, but with the low amp draw of a residential refrigerator (which may or may not be running at the time of switching) I don't thing it is worth the effort.

Shore power is exactly what the refrigerator was designed to run on, so see zero issues.

I agree with Brett but as a recent install do you have a transfer switch? When I installed mine I left the two power sources from my NoCold (shore plus MSW inverter) and added a PSW inverter. When traveling I plug it into the PSW which has a transfer switch and when Snowbirding I plug it into the shore power. The MSW is for an emergency if my PSW has a problem. I should have mounted these outlets easier to get at.
My transfer reacts so fast that the compressor does not stop running... not so for some of the electronics.

The person who recently installed it should know.

Oldman he didn't know that's why I'm checking with you smart people

Shore power, nothing special
Do you have an auto transfer switch in the circuit ?

Yes? The only thing you have to be aware of is battery condition
As long as the batteries get kept st a proper level of charge you Ares good to go

N no transfer switch
Manual mode switching ? Moving the plug?
Then turn off fridge before swapping the plug
This is to protect the plug and the sockets from arcing
Which pits them and causes damage heat and burning

Someone with hands on does not know but we might??? Good Luck

Yes I have an automatic transfer switch

Actually, the issues is whether you have TWO transfer switches:

Shore power vs generator

Inverter output so it defers to shore power when available and switches to inverter for some circuits including the refrigerator. Again, many inverter/chargers have this ATS built in. WHAT INVERTER/CHARGER DO YOU HAVE?

Do you have a dedicated inverter used just for the fridge? It sounds like that's what you are saying. If so then shore power or generator power would make no difference at all and you would not need to do anything to the fridge when changing power sources.

Have a 1220 Kisae Pure Sine inverter with 4 deep cycle Golf Batteries from Sam's Club. I want to learn as much as I can about about this residential refrigerator. It is a Magic Chef 10.cu ft and so far have been very happy with it. You hear positive and negative about these things and just don't want to learn the hard way.
My biggest concern is when you disconnect off of shore power and want to use the generator for ac power do you have to completely unplug the fridge until the generator is stabilized.
