How Many Watts Do You Need To Run A Refrigerator?

The refrigerator is to a delicious meal what a gas station is to a fun road trip. Whether a cold soda on a sunny day or an ice cream for binge-watching movies, it is an essential appliance in any household. But, it requires electricity to preserve food items, which can be a problem for mobile homes or during power cuts.

Therefore, it is essential to understand how many Watts you need to run a refrigerator. This piece will also let you know how to build a suitable power backup for it.

How Many Watts To Run a Refrigerator?

The power consumption of your refrigerator depends on its cooling capacity and storage space. Multi-compartment refrigerators require more electricity than single-story ones, as they require separate spaces as closed systems. If you have a tiny 50 L refrigerator, it can efficiently run on a 300-Watt AC power supply. Larger refrigerators, like those with 240 L or more capacity, require at least 1800 Watts.

The type of refrigerator is also a crucial factor. Many modern refrigerators come with built-in inverters. So, they may look power-hungry with all the bells and whistles. Yet, such refrigerators can be much more power-efficient than their non-inverter counterparts. Variants that have freezers require more energy because of the considerable temperature difference.

You can check the exact power requirements for your refrigerator on the back panel. It is usually present just below the thermal coils. Alternatively, you can browse the specifications in the manual to verify the same.

Will 1500 Watts Run a Refrigerator?

An AC power output of 24V 1500 Watts is enough to run a regular dual-compartment refrigerator. It works even though one compartment is a freezer. Such refrigerators should have a storage capacity of around 300 L. Bigger refrigerators may require more power.

What Wattage Generator Do I Need for a Refrigerator?

If you need to run a household 250-liter refrigerator, you may need a 1500-Watt generator. The Wattage also needs to account for other electronic devices that you may run alongside the fridge. You don’t want the fuses blown when you turn on the TV while enjoying some cold beverage.

Since there are different types of generators, it counts to choose the one that best suits your needs. You may want an inverter-based pure sine wave generator if you need one for a refrigerator. It keeps the output stable, even as you switch on more appliances on the same circuit.

Will a 2000-Watt Inverter Run a Refrigerator?

A 2000-Watt inverter can effectively run a refrigerator with a capacity of 300 liters or less. Still, you need to ensure that the batteries last long enough to keep all articles refrigerated. Such refrigerators require around 1300 Watts. So, if you plan to run the fridge for 6 hours, you need a battery capacity of at least 120 Ah.

It would be great to go way above 120 Ah if you plan to run multiple appliances. The best bet is to go past 500 Ah so that you never drain more than half the battery, even during extended power cuts.

What Size Generator Do I Need to Run a Full-Size Refrigerator?

Full-sized refrigerators require at least 1800 Watts of constant AC power supply. Thus, to stay on the safe side, you should utilize a generator with a minimum supply capacity of 2500 Watts.
