Quick Answer

Question How long will a 12 Volt RV refrigerator run on battery?

In general, a 12V-50Ah battery can run a 2 cubic feet 12V fridge for 35 to 50 hours before it’s completely depleted. A 10 cubic feet RV refrigerator can run on the same battery for only 10 to 15 hours.

How much power does a 12V compressor fridge use?

Compressor fridges are far more efficient when run on electricity 12v or 240v. A 3 way fridge running on 12v will draw approx 9A plus continuously (+9A per hour). A 12v compressor fridge power requirement can be as low as 0.4A per hour for a 40 litre fridge.

How does a 12 volt refrigerator work in an RV?

A 12 volt RV refrigerator runs primarily on the 12-volt DC power from your rig’s house batteries (or potentially your car or truck’s starter battery). These refrigerators operate solely on electricity, as opposed to absorption or two-way RV refrigerators that can burn propane to power their cooling system.

Do 12 volt RV refrigerators need to be level?

Most recreational refrigerators will work properly as long as they are within 2 degrees of level side to side and 4 degrees of level front to back.

How many amps does a 12 volt RV refrigerator use?

12V Load RV Amp Draw Table

Load Watts Amps @12V
12V Outlet, Socket 120-130 10
12V Outlet, USB 25 2.1
AC/DC RV Fridge 50-180 4-13.5
AC/DC Fridge/Freezer, Portable 8-30 0.7-2.3

How many amps does a 12V fridge draw?

A 12 volt fridge uses between 30 and 55 Ah (amp hours) per day on average.

Can I run a 12V fridge off a solar panel?

Powering a 12-volt fridge through a solar panel is possible, but it’s important to factor in the panel size, its watt usage, the wattage of the fridge, and your overall power consumption. In addition, a deep-cycle battery is a smart investment to extend the run time of your fridge on a solar panel.

What size solar panel do I need to run a 12V fridge?


As a rule of thumb, we recommend slightly less than double the Ah of battery storage in watts of solar. So a 100Ah battery would have approximately 200 watts of solar.

Will a 12V fridge drain my car battery?

There is absolutely no question – a fridge cooler will drain you car battery. On average, fridge coolers will draw 4.5A at 12V. As they are thermostatically regulated, you can expect the compressor to be running about 25% of the time.

Does RV fridge work better on propane?

Many agree that RV refrigerators work better on electricity, as it keeps the food fresh and cold for a longer period. On the other hand, a gas RV fridge will cool faster and stay colder even in high temperatures.

Do RV refrigerators work off propane?

RV refrigerators can run off of either a 120 volt electrical or an LP gas system. An RV propane refrigerator makes it possible to keep your food and beverages cold when there are no electrical hook ups available.

Will RV fridge run on 110?

Unlike your refrigerator at home, RV refrigerators typically require a 12 Volt DC source to run “the brains” and a 110 Volt A/C source or propane to run the “cooling” part.

What happens if RV is not level?

If your RV is not properly level then your tank sensors will not read correctly. Depending on the slope, your sensors may read as more full or more empty than they really are. This can even affect drainage by not allowing all of your tanks to empty.

Should I leave my RV refrigerator on all the time?

Ultimately, it’s possible to keep your RV refrigerator running all the time if you don’t go anywhere. However, if you’re intent on travel, then powering down and disconnecting it from the power supply or propane source, is best.

Will RV fridge run off battery?

An RV refrigerator will run off of the battery if your fridge model is set up for it or if it uses propane too. An absorption fridge will run on batteries only for about 3 hours but if using propane too it will last for weeks. A residential RV fridge will last for about 12 hours on batteries.

How much solar power do you need for an RV Fridge?

In order to power that fridge using solar power, you would need about two to three solar panels. Average solar panels produce approximately 250 to 400 Watts of power. But you are not using an average refrigerator in your RV. Most likely, you need to power a 12V fridge, which is smaller.

How many amps does a Dometic RV refrigerator use?

The fridge takes 5 amps. The panels produce up to 15 amps in total.

How many amps does a Dometic 3 Way fridge draw?

Based on 150W, your fridge will draw a constant 12.5amps
there is no thermostat control on 12v. Unlike new 12v only fridges which use compressors and use as little as 2amps, the 3-way fridges use heater elements – use lots of amps.

Can a refrigerator be on a 15 amp circuit?

Most refrigerators run between 3 to 6 amps, with that said, a refrigerator can spike at peak usage up to 15 amps. It’s best to take into consideration worst case scenarios. You should have refrigerators and freezers installed on a 15-20 amp dedicated 120 volt circuit.

Will a 100W solar panel run a fridge?

As a general rule, 100 watt solar panel can run a refrigerator for a short time only and would also need a battery. 100 watts of solar panels can generate on average 400 watt-hours of energy per day. A refrigerator with combined freezer needs 2000 watt-hours/day.

Can a 100 watt solar panel run a RV refrigerator?

RV fridge consumes about 1000Wh of energy per day. If the 100W solar panel is powering the fridge through a battery, it is possible to run the fridge for 8 to 16 hours per day.

Will a 200W solar panel run a fridge?

Yes, a 200 W Solar panel can run a fridge. However, it cannot run all types of fridges. It depends on the size and the power the fridge consumes. A 200W solar panel would produce anywhere between 0.8 kWh and 1.1 kWh per day.

Can a solar panel run a camping fridge?

The answer is simple, and it goes by the name of solar power. Having small solar panels for camping will ensure that some of the most essential pieces of equipment in your campsite are up and running. That also includes your refrigerator, or could even extend to a solar panel fridge.
