Off grid refrigerator

The one thousand dollar is what currency? US or EC dollars? As bad as Jamaica we pay 50 US cents per kwh. if is US currency that is really steep.

Yes I am sure, I can't pay a thousand dollars monthly bill, I don't have a thousand dollar income, thanks for the replay with that formula, I will do this like my brother in-law did, buying everything one thing at a time until all was done, he lives at the very east of the island, by the way I found all the electrical bills since January all say I consumed between 500 and 700 kWhin a 30 day period, I assumed kWh means kilowatts per hour..................thanks AZ

A 1,055.10 monthly bills is to much for a house that is empty from 6AM to 6PM, like I mention in other post is not the electricity price, is the charge of fuel to generate what they say I am consuming, 215.$ is what the meter says I consumed everything else is fuel, thanks for the replay...
Forgot to mention, I am off grid right now, I asked the energy company to remove the meter................AZ

The amount you spend on fuel is high but a solar battery system just to run your refrigerator may have an up front cost that is pretty steep.

Without really knowing how many watt hours that fridge uses we can estimate it at about (115v x 6a ~ 690watts). So lets just use a figure of 12hours a day it is running those 690 watts. That comes to about 8300 watt hours a day.

You would need a 48volt 1000Ah battery system. That is 24 x 2volt 1000Ah batteries at about $400/ea plus shipping.

At least you are located close to the equator so you will have decent amount of sunlight. You will need a minimum of 2000 watts of panels (~$1/watt), a 60A MPPT Charge controller(~$500), a 48volt 1500watt pure sine wave inverter (~$600).

Plus all of the wiring, fusing, panel racking and storage building that is needed. You are probably looking at $15,000 up front costs and will have to replace those batteries in 4 - 5 years if you take real good care of them.

Are you sure you want to go off grid to run that fridge?

Get a Kill-a-watt meter and run the frig for a week or 2 with that on it to get an idea as to how much power it uses.

Hopefully you realize that going off grid will cost you more than staying on the grid. Usually 10 to 20 times more.

Hello to you all, I want to start with the refrigerator, all I could find was Voltage 115V Amps 6.0 Hertz 60, if I want this 24/7 operational how many batteries, solar panels and inverter do I need? Read on web many info but not all clear yet, found a few off grid starter kits some are 100watts per panel some are 20, 60 watts and I ended up not knowing what to look for, my location is the Caribbean Puerto Rico to be specific the West, live away from the city very quite and nearest neighbor is 70 or more feet away............Why the fridge only? Because I can't buy a full off grid for the entire house, and by starting with the most important thing in the house wish is the fridge I can start understanding how this off grid really works,have visited few houses some off grid some tied grid but since it is already assembled I can't visualize the installation, is this was a car or SUV to be converted to turbo or supercharged then I am good at it but it isn't, thanks in advance ..............AZ
