Likewise,Â How many amp hours do I need to run a fridge?

Refrigerator amps are the amount of electrical current it’s compressor uses to cool it’s compartment. Amperage for most household refrigerators, is anywhere from 3 to 5 if the voltage is 120. A 15 to 20 amp dedicated circuit is required because the in-rush amperage is much higher.

### Does a fridge need a 20 amp circuit?

A modern refrigerator requires a dedicated 20-amp, 120/125-volt circuit. You may currently have a smaller refrigerator plugged into a general lighting circuit, but during any major remodeling, a dedicated 120/125-volt circuit for the refrigerator should be installed.

### How big a deep cycle battery do I need?

As a basic rule of thumb, you can remember that a 100Ah AGM deep cycle battery can provide 1 amp for 100 hours, 2 amps for 50 hours, 3 amps for 33 hours,… Keep in mind this is a rough estimate, as the battery capacity will change a little depending on how fast your battery is being drained.

### How long will my battery run my fridge?

A decent fridge around that size under 30 degrees ambient temperature shouldn’t use more than around 30 – 40 amp hours a day. Normal deep cycle batteries have a cycle life of about 1500 times, when you only use 30% of their capacity.

### Do RV refrigerators run on 12 volt?

Getting to Know Common RV Refrigerators And that’s for chilling food that is already cold, let alone food that’s at room temperature. … This means that the refrigerator will run as if it were using electricity even though it is only using 12-volt batteries.

### How much power does an RV Fridge use?

The small RV refrigerator ended up using about 5 kWh of power per day. Our entire battery bank is about 24 kWh. This means that nearly every day about 20% to 25% of all our usable battery power would need to go to powering the refrigerator.
