Most refrigerators require a pure sine wave inverter to work properly with the high torque motor. Most RV's with residential refrigerators use 4 golf cart batteries, some have 4 of the 8D battery at 120 pounds each, or the energy storage of 8 golf cart batteries.
I would also recommend a pair of 120 watt solar panels as a minimum, but probably a 400 watt system if you do any dry camping.
SunElec.comInverter size should be around 1,000 watts, and then it should not overheat.
I have heard that Samsung refrigerators are more likely to be happy with a inverter.
Some refrigerators have the condensor welded to the inside of the metal jacket around the refrigerator, so when running the heat is disapated by warming the outside steel shell of the refrigerator. this is not very efficient, and should be avoided. One with a steel coil and fan under the refrigerator is more efficient, and less likely to warm the sides, and heat the interior of the refrigerator. Also being built into a cabinet, and refrigerator with a shell style condenser, it will heat up the sidewalls of the refrigerator, normally in a home this is OK they are all exposed to air in the room, but not when mounted in a RV cabinet.
