Refrigerator question

I've seen a lot of people use the MagicChef 9.9 cu ft refrigerators from Home Depot in RVs and bus conversions, also BJs has a sale on a 7.5 cu ft Igloo coming up...I would love to grab one as they're cheap and sufficient but the manufacturers state they aren't designed to be used with an inverter...can anyone explain why? From what I read in the MagicChef reviews, people also mentioned they should be unplugged while driving, is that limited to regular RVs? Would a solar setup change that?

If it works on a domestic circuit, it will work with a pure sine-wave inverter. The manufacturer might be concerned about warranty claims if people try to run it from a modified sine-wave.

I can't say anything about the specific brands you mentioned. I ran cheap WalMart dorm fridges in a semi for years on a modified sine inverter with no problems. Also had the same thing in a camper before the bus. I've got a Whirlpool in the bus that ran just fine on a modified inverter until I switched to a pure sine wave inverter.
I think you'll find that most of the dorm and low end fridges have basically the same Chinese guts.

After 3 years of bus duty our 4.5cf Vissani **** the bed.

Just installed a new Igloo, same size.

PSW inverter.

Things I've learned;
Operating in interior temps below 50f is hard on compressors. The oil gets thick and stresses it. I've run it lots while sitting in the DW in cold wx.

The new Igloo uses .8a when running, old Vissani used 1.5a.

The Xantrex 2000 uses .9a.

Made my post while there was an unknown to me site outage. I guess that's why the double post.

Just for the record, there are now some really outstanding 12 volt fridge/freezers on the market. I am looking at one by Whynter that a bunch of local blue water sailors use and are in love with. These are not the funky cold plate rigs but new technology compressors. One guy told me he gets on board, turns it on and in about thirty minutes, everything he put in the freezer side is frozen solid and he has never had an issue. Sounds good to me. They are all chest type and I am working out my tiny kitchen area to accommodate one.
