How to power a fridge with a generator

When power outages occur, you need to power your fridge by using a generator. This article will help you along with some other questions you may have;

  • How to power a fridge with a generator?
  • What type of generator do you need to run a fridge?
  • What is the best generator to power a fridge?

Analyze the amount of power you need to run the fridge. When the generator’s motor is running, you can connect your fridge and turn it on. In most cases, a fridge requires 1000-2000 watts of power to operate, so a generator that provides 2000 watts or more should do the job. The best generator to power a fridge can deliver 3000 watts or more.

Steps to run a fridge with a generator 

Facing constant power outages not only disrupts your daily activities, but it can also be a nightmare for your appliances, especially the fridge since there is a high risk for food items to get wasted. The ideal solution is to get a generator, but connecting it to the fridge and turning on the machine won’t work. So, let’s have a look at the proper steps to power your fridge.

1. Inspect the wattage required for the fridge to run

First, you need to check the watt (measurement of power) required to run a fridge, which will be available on the label or manual of your fridge. A standard fridge with a freezer section estimates 6.5 amps at 60 hertz, followed by 110 to 127 volt AC. Generally, the fridge operates at 800 watts with 1,600 as the starting watt. Nevertheless, you can also calculate by multiplying the flowing watt by 1.5 to figure out the required watt for your fridge to start. Finally, the result of the calculation is the wattage needed from the generator to start the unit.

2. Analyze the generator’s wattage 

Identify how many watts the generator can deliver for the smooth running of the unit. A standard generator’s receptacle produces 20 amps,60 hertz at 120 volts, making it idle for running a fridge. For example, a generator rated with 1,500 watts can run a fridge with 1000 watts. Still, if you choose a generator with an output rating of 800 watts, there are high chances of a power trip raising the need to start the fridge over again.

3. Check other accessories running via the same generator 

If you plan to power other equipment/machines with the same generator used for your fridge, double-check that the generator can handle the load. Make your calculations on how many watts will be needed to run the fridge and how many extra watts can be spared to run another machine.

4. Placement of the generator 

Ensure that the generator is placed in an open space as it may lead to carbon monoxide poisoning and other injuries. Maintain a distance of 20 feet from your residence. Also, the direct exhaust of the generator should not release towards your home. Connect it with a 14-gauge extension cord. Please remember to use high-quality extension cords designed explicitly for generators that are 10-30 feet and can support 7500 watts. 

5. Connect the generator to the fridge 

Since your generator is advised to be placed outdoors, the extension cord connecting to the generator needs to run through a window or hallway. You can also try using a transfer switch (an electrical switch) for your connection, as it will monitor and allow your wiring system to run appliances through the generator. It will also separate the generator power from the electric utility, making it convenient.

6. Start the generator 

Run your generator, allowing it to stabilize and plug your fridge into the socket of the extension cord, and press that switch button. Your fridge should be running but do a quick check if everything is operating accurately. 

What kind of generator to choose?

Before getting a generator, you need to identify the wattage requirements of your fridge, i.e., starting and running watts. Once identified, try to get a mid-level generator with above 2000 watts that can support your fridge and other appliances. It is recommended to get a dual fuel generator as it runs on propane, a cheaper gasoline option. Also, consider getting an inverter generator that produces less noise, is 100% safe, and is compatible with any electronics.

What is the ideal generator?
