electricity – Inexpensive way of permanently running a fridge with solar power? – GWC Mag

I have about USD $3,000 that I can use to invest in solar-powered alternatives at my apartment. Since I live in Latin America, my small rooftop receives tons of sunlight 12 hours/day but is not big enough to hold a bunch of panels.

The appliances that consume the most electricity now are the fridge (which is always on), the 18K inverter A/C (which is on about 8-10 hrs/day), and the washer/dryer.

Since the fridge is the only appliance that’s always on, I guess my question is: what’s the most inexpensive way to constantly power this appliance with solar energy?

I saw this Costco ad for a portable power station and thought that maybe something like this would help.

On a related note, a local group that deals with solar power alternatives in the Caribbean posted this battery array alternative. Would this be a possible solution for me?
