How long can a DC Freezer Wholesaler refrigerator run on a 12-volt battery?
A typical ENERGY STAR refrigerator consumes less than 300 kilowatt-hours per year and can run for 30 – 35 hours on a fully charged 12 volt 100 ampere hour battery. This varies with the ambient temperature around the refrigerator and the efficiency of the DC to AC power inverter being used.
Find out the power consumption level of the refrigerator:
Power consumption is a measure of the amount of power used by the refrigerator over time. The refrigerator contains a cooling compressor. However, they do not run continuously, but cycle on and off, so the refrigerator consumes significantly less power than the nameplate wattage or amperage over a period of time. The amperage or wattage on the nameplate will specify the amount of electricity consumed when the compressor is started. For example; if the compressor only runs for 30% of the time when the refrigerator is energized, the total power consumption will only be 30% of the operating (nameplate) amperage.
The power consumption will vary with the ambient temperature or the insulation value, which will cause the compressor to run more or less. Many traditional household refrigerators are rated as efficient by Energy Star, but most commercial and pharmacy refrigerators generally do not meet the standards that Energy Star uses to endorse products.
