Determining the power consumption of a DC freezer's solar freezer and refrigerator
Your freezer nameplate will most likely show details on power consumption. You can check the body of the refrigerator for this label, which mentions the voltage and current requirements of the appliance. Multiply these two values together to get the desired wattage.
For example, if your refrigerator mentions 4.5 amps and 120 volts, your requirement (in watts) for a solar device will be 540.
battery size for solar refrigerator freezer
About 1400 watt-hours of power can be stored in a medium-sized battery. Since it is recommended that you keep the battery at least half charged at all times, you have about 720 watt-hours available.
Make sure you choose a high-capacity battery, as the sun may not shine every day.
NOTE: If you want the solar freezer to run for 4 days and the unit consumes 840 watts per day, you will need to generate and store at least approximately 3400 watts.
