Residential Refrigerator Installation

I brought my 23.5 cu. ft. Samsung in through the entrance door with doors on the refer removed. It was actually narrower than the 12 cu. ft. norcold that went out the same door. The samsung was also lighter and will run on a MSW inverter as a Samsung tech. told me that the input voltage is converted to DC voltage and the entire refer runs on DC. I installed a 1000 watt PSW inverter before finding this out. I had 2 control panels go bad and thought it was the MSW inverter causing it, but after installing the inverter the second service tech said no it was a bad panel design which has been upgraded and no more problems for 4 yrs. I leave the refer on 24-7-365. I have 4 trojan 6 volt house batteries and after a day of driving then watching tv a couple of hours a few lights on and a cpap machine all night my battery voltage will be about 12.4 in the morning, so this 23.5 cu. ft. side by side is very efficient.
PM me if you have any questions.
