Once it's down to temperature you can just run it while the sun is out (so the battery is not needed), to keep it cold enough that your meat doesn't spoil
There are designs online to Run freezer off an inverter and battery. Normally the freezer will draw more than can be provided by solar and inverter.
The design used a electrical thermo switch that turns on the inverter when the temp goes up, and a huge tub filled with frozen water to act as a thermal battery. So it stays frozen longer then when the temp goes up, the inverter kicks on cools it down again. Then Turns off
Wouldn't you need a huge battery and high wattage solar panel system to run a freezer for a week?
Edit: I asked Grok. Here is it's answer:
Given these considerations, here's what you might look for:
6 x 300W solar panels for generation.
Battery bank capable of storing 8-9 kWh, which might translate to something like 400Ah at 24V or equivalent in a 48V system for better efficiency.
1000-1500W inverter for power conversion.
MPPT charge controller to handle the power from the panels efficiently.
I can't do that in an apartment unfortunately.

Good point. Now to convince myself to spend $$$ on a solar panel kit or just buy some MREs
Sometimes you can find a bargain online somewhere. Look into surplus & etc
