I looked a little online store and class A refrigerators are given for about 170 to 250 kWh per year
which gives at worst 700Wh per 24h.
Which UPS to a fridge 130w
For the power peak at start-up, it would be interesting to test capacities capable of collecting the necessary energy.
When the fridge is running and the primary source of electricity is working, it is important not to go through the batteries which take up and lose too much power.
Moreover, it would be more interesting to add cold blocks in the "frozen" part of the fridge to store cold when the primary source produces, it would be the most efficient solution, by far: an accumulation fridge: - )

See you soon !
Well, I received my new inverter (a PowerBright 1500/3000 pseudo-sine) it works perfectly with the fridge. I did the test by plugging in the computer + the TV + some lamps of my lighting and nothing changed when it started. It's already a good thing.
I controlled what the fridge turns with a consometer. On 12 o'clock from 20 p.m. to 8 a.m. it turned 2 hours. So I estimate in summer and by opening and closing its door, that it should turn 6 hours a day by calculating wide. When it starts, it spins between 24 minutes and 15 minutes before cutting itself off.

pseudo sinus is really a regretable term: it means square signals just well chosen to be approximately equivalent to a sinusoid: it is very bad for asynchronous motors: it makes them heat much more than in true sinusoids: damage to the fridges that already heat up a lot in normal sinusoid
there are some real sine wave inverters not too expensive: you should take those preferably
pseudo sine is for troubleshooting, for emergency power supply during power outages: for real autonomy you need real sine
