cheap 220v system for AirCon & Ref

Hello, I live in the Philippines and experience a lot of power outages.
When the power goes out its out for 1 - 12 hours, this happens about once a week, ya its that bad.
I really need to get a basic system up and running so my food doesnt go bad and I can stay cool too.
Right now I keep ice in the freezer & when its out I will take all the ice put it in the refrigerator.
I would like to build a cheap 220v system for running my refrigerator and a window Air Con (600 watts)
I dont know what the power is of the ref, since I will be getting a new one soon, 10 Cu Ft
Needless to say, being in the Philippines, I dont have a lot of money to be able to get a really nice setup & will likely have to start with lead batteries for now & upgrade to better ones later.

So, all that said, is there a video that Will has done that has info on a cheap system that can power said devices?

I don't know if he's done a video, but he does have a "blueprint" page: https://www.mobile-solarpower.com/ultra-sized-systems-run-an-air-conditioner.html

It presumes life in a van in North America, so your arithmetic would be different.

There are Aussies on this forum who might have something useful to contribute. Maybe keep an eye out for them.

How much is your buget?

Batteries and inverter to handle 700watts, with surge to start compressors I would get an inverter/charger first, start with one SLA 100Ah battery then add them as funds build.
The 1500watt LF samilex can handle 4500watts for 20 seconds of startup.. and keep your battery charged. Adding in a second battery then a third will extend your runtime...

If you have power most of the time what you need is a basically an oversized ups backup - a battery, a charger and an inverter.

Also consider that you can get a generator for under 1 kw load for around 150 us dollars (at least in thailand). sure, it uses gasoline but the initial cost is a lot less. for having off grid power enough to run an air conditioner that is the cheapest initial cost you can get - it's way cheaper than buying deep cycle batteries that could run your air conditioner just for 1-2 hours - and even if you buy the batteries it's still worth it for charging them if theres a longer outage.

Harbor freight has an inverter generator for around $700 that is real quiet. Honda clone they say

I didn't get my refrigerator done last summer, so no photos
BUT
I do know of a guy who did it and my system is modeled after his.

THE BOX:
Without drawings, the best way to describe it is; a box in a box.
It's made of concrete, no aggregate. A concrete box about 48" x 24" x 16"H.
2 liter soda pop bottles are filled with 100% saturated brine. These go against
the inside wall of the box. There is another concrete wall that separates the
bottles from the food. After the concrete has cured, the entire box is coated
with epoxy. I can't supply the link for the epoxy on the forum, but there are a
couple of suppliers whom I like. The box is then enclosed with a wood, or
metal box. Between the concrete inner box, and the outer box are multiple
layers of pink board insulation, and aluminum foil. It takes a lot of insulation.

ICE GENERATOR
The ice generator is a small dorm fridge. The condenser and evaporator each
go into a bath to increase the effeciency. The unit is powered by PV panels. I
haven't tested the unit but the designer said it produces "about" 28# ice / hour.
The 2 liter bottles go in the bath, and the brine in the bottles is frozen.

Not the best description, but I hope this helps.
