Pregunta Generator/battery
Hi, can someone recommend generator or some kind of large power bank that can be charged when the power is on and later could be used to keep the refrigerator running. I'm not sure if such thing exists

Jackery is popular also. Anker/Solix I don’t hear about as much, but is big in the states. Not familiar with Bluetti.

Anker products are very good, but harder to find on the island. You may be able to ship one. EcoFlow is pretty much the standard on island and will keep your fridge and fan running for a night, then need to recharged the next day.

Any LiFePO4 power station. Look for capacity according to your needs, output ports and charging methods. Yes, you want to be able to charge through the AC wall outlet, but you also want to be able to add solar panels in the future without the need of buying a new power station.
With around 1000W/h it allows aprox. 6hs of refrigerator use, a rechargable fan and some mobile phone devices. Something like a 2000W/h capacity will let you add a freezer too, or double the running time for your refrigerator. Look for at least 500-600W solar entry (with around 40-60V and 15-20A minimun for solar entry, it's hard to find any solar panel with less than those specs for under 800usd here, only the ones with 500-600W will sell for under 400usd).
If possible, look for one that allows reducing charging power to a healthy speed (like 500-800W entry, Ecoflow is great with this). And always check the subreddits that discuss issues with certain brands and types of devices. You need to learn how to take care of your power station to not lose your investment in 6 months!

Right now depending on how much time of electricity they can access daily, solar panels are a must, to fully recharge the batteries.

People in Cuba have had Ecoflow batteries, probably shipped from their relatives in the USA.

Which mode would be enough to run the refrigerator for few hours?

EcoFlow Delta 2 should give you 5 hours of machine operation, which is more than 5 hours of total time because the machine cycles between start - stop.
EcoFlow now has the newer Delta 3 Classic for pretty much the same price which, on paper, has the same specification but it has worst electronics inside.

Por primera vez entro en una conversación Redit y me encontre con esta conversación.... me gustaría preguntar a cudadanos (hermanos) cubanos si es verdad que ustedes desean ser colonia de EEUU...es verdad que la situación es insoportable? y que su Gobierno es dictatorial e injusto?.... soy Mexicana y siento un enorme cariño por el pueblo Cubano...en mi niñez tuve vecinos cubanos -era una familia de atletas- que se convirtieron en mi familia por algunos años.... nunca he tenido oportunidad de viajar y conocer pero me parece inquietante todo lo que se dice.... es verdad que es horrible su situación? es verdad que su Gobierno es injusto e incompetente? abrazo de corazón

Fridges take a lot of power, anything that would run it for a while would probably cost a lot.
I think you'd be better off trying to maximize how long things stay cold: when the power is on, wait until everything is properly cold, then put a bucket of water in the freezer (wide and shallow will probably be faster). Don't do it before stuff is cold, or the power might go out while the fridge is still struggling to both re-cool your food and freeze the water. Then once you have a good block of ice, treat the freezer like an ice box - don't open the door more than you need to.
If your fridge has coils on the back or bottom, you can insulate the freezer with blankets, but leave the coils open, as the fridge works by giving off heat. If you have cardboard or styrofoam, you can increase insulation, like shown in this post here: https://www.reddit.com/r/ZeroWaste/comments/o1a3vi/a_more_efficient_refrigerator_covered_it_in_2/
