Energy guide

[SIZE=2]I bought a small freezer for a solar cabin. It says it’s estimated yearly usage is 212 kwh per year. I divided this by 365 which equaled 581w per day, I’m assuming that’s with the freezer set half on the thermostat and maybe 3/4 filled.[/SIZE]

[FONT=Arial][SIZE=2]Freezer says it uses 1.3 amps at 115 volts which equals 150w per hour.
I have been testing the freezer on low to see how long and often it runs without opening it, and it runs approximately 20 minutes an hour or approximately 8 hours per day, at 150w per hour, equalling 1200w per day or 438 kwh per year. Over twice as much as the energy guide says even on low. [/SIZE][/FONT]

[FONT=Arial][SIZE=2]My question is, what am I missing? When the freezer is running, is it not always using the 1.3 amps because the compressor cycles, or something like that? Can anyone explain this? Thank you
