So, What Size Generator For Food Truck?


The size of the generator for a food truck depends on the power needs of your equipment. A good rule of thumb is to choose a generator with a wattage output that is 20% higher than your equipment’s combined wattage.

A generator with a minimum of 3000 watts or 4000 watts is usually sufficient for most food trucks. However, it’s important to consider factors such as fuel efficiency, noise level, portability, and price when choosing a generator. Consulting with a professional can also help ensure you choose the right generator for your needs.


Factors to Consider When Choosing a Generator


When choosing the right generator for your food truck, there are several factors to consider. These include:

Power Requirements of Your Catering Truck Equipment

The power requirements of your food truck equipment will determine the size of the generator you need. Make sure to consider the starting and running wattage of your appliances to get an accurate estimate of the total power needed.

Fuel Type and Efficiency of the Generator

Generators can run on gasoline, propane, or diesel fuel. Each fuel type has its pros and cons, so it’s important to choose the one that best fits your needs. Consider the efficiency of the generator as well, as this can impact the amount of fuel you will need to carry.

Portability and Noise Level

Food trucks require generators that are easy to move and transport. Consider the weight and size of the generator, as well as its noise level, as you will want to avoid disturbing your customers with excessive noise.

Budget Considerations

Generators can vary in price, so it’s important to consider your budget when choosing the right generator for your food truck. Remember that investing in a high-quality generator can save you money in the long run by avoiding costly breakdowns and repairs.

Availability of Fuel and Maintenance Options

Consider the availability of fuel for your generator, as well as the maintenance options available in your area. Make sure to choose a generator that is easy to maintain and repair, and that you have access to the necessary fuel sources.

By taking these factors into consideration, you can choose the right generator for your food truck that meets your power needs, budget, and logistical requirements.

Calculating Power Requirements for Your Catering Truck


Calculating the power requirements for your food truck is an essential step in choosing the right size generator. By understanding the power consumption of all the electrical equipment in your truck, you can calculate the total wattage needed and choose a generator that can handle your power needs.

List All Electrical Equipment and Their Power Requirements

Start by listing all the electrical equipment in your food truck that requires power, such as refrigerators, freezers, ovens, microwaves, grills, fryers, coffee makers, blenders, POS systems, and lighting. Then, identify the power requirements of each item. You can find this information on the equipment’s label, manual, or online specifications.

Calculate the Total Wattage Needed

Once you have a list of all the electrical equipment and their power requirements, you need to calculate the total wattage needed. To do this, you can use the following formula:

Total Wattage = Power Requirement of Each Item x Quantity of Each Item

For example, if you have two refrigerators that each require 500 watts and one microwave that requires 1000 watts, the total wattage needed would be:

Total Wattage = (500 watts x 2) + 1000 watts = 2000 watts

Using an online wattage calculator to determine the total power needed

Using an online wattage calculator is a convenient way to determine the total power needed for your food truck. These calculators allow you to input the wattage ratings of your appliances and estimate how many will be running at the same time. The calculator will then give you an estimate of the total power needed for your food truck equipment. Be sure to consider the starting and running wattage of your appliances when using a wattage calculator to get an accurate estimate.

Examples of Common Food Truck Equipment and Their Power Consumption

Examples of common Catering truck equipment and their power consumption:

  • Refrigerators: 400-800 watts
  • Freezers: 800-1200 watts
  • Ovens: 1500-3000 watts
  • Microwaves: 1000-1500 watts
  • Grills: 1000-3000 watts
  • Fryers: 2000-5000 watts
  • Coffee makers: 800-1500 watts
  • Blenders: 300-800 watts
  • POS systems: 200-400 watts
  • Lighting: 50-200 watts

It’s important to note that some equipment may have a higher power consumption during startup or peak usage, so make sure to factor in those requirements as well.

By calculating the power requirements of your food truck equipment and determining the total wattage needed, you can choose a generator that can handle your power needs and ensure that all equipment runs smoothly.

Types of Generators Using Catering Trucks?


Food trucks typically use portable generators that can be easily transported and provide enough power to run the necessary equipment. There are three main types of generators that food trucks use:

  1. Gasoline Generators: Gasoline generators are the most commonly used type of generator for food trucks. They are cheap and easy to find, making them a popular choice. However, gasoline generators can be noisy and produce exhaust fumes, which can be a concern for food safety.
  2. Propane Generators: Propane generators are another popular option for food trucks. They are quieter and produce fewer emissions than gasoline generators, making them a good choice for outdoor events. However, propane generators can be more expensive and may require a larger storage tank for the fuel.
  3. Diesel Generators: Diesel generators are a good option for larger food trucks that require more power. They are fuel-efficient and provide reliable power, making them a good choice for food trucks that operate for long periods of time. However, diesel generators can be more expensive than gasoline or propane generators.
  4. Solar Power: Solar power generators are a renewable and environmentally-friendly option for food trucks. They do not produce emissions and can be a good choice for outdoor events. However, they can be expensive and may not provide enough power for all food truck equipment.

When choosing a fuel type, consider the fuel efficiency and cost of each option. Diesel generators are generally more fuel-efficient than gasoline generators, but they may be more expensive to purchase. Propane generators can be more expensive to operate due to the cost of propane, but they are more fuel-efficient than gasoline generators.

Environmental impact is another important consideration. Gasoline and diesel generators produce emissions that can be harmful to the environment and pose a food safety risk. Propane and solar power generators produce fewer emissions and are better for the environment.

Ultimately, the fuel type and efficiency of your generator will depend on your specific needs and preferences. Consider the power requirements of your food truck equipment, the portability and noise level of the generator, and your budget when choosing the right fuel type and efficiency for your food truck generator.


Generator Sizes for Different Types of Food Trucks


The size of your food truck will play a role in determining the appropriate generator size. Here are some general recommendations for generator sizes based on the size, type of your food truck.

Small Food Truck (less than 100 sq. ft.): A small food truck typically requires a generator with a capacity of 2,000 to 3,000 watts. This should be sufficient to power basic equipment such as a refrigerator, freezer, and a few small appliances.

Medium Food Truck (100-200 sq. ft.): A medium-sized food truck will require a generator with a capacity of 4,000 to 5,000 watts. This should be enough to power additional equipment such as a griddle, fryer, and more refrigeration and cooking equipment.

Large Food Truck (more than 200 sq. ft.): A large food truck will require a generator with a capacity of at least 7,000 watts. This will be sufficient to power multiple cooking and refrigeration appliances, along with other equipment such as lighting and sound systems.

It’s important to note that these recommendations are general guidelines, and the specific power requirements of your food truck may vary based on the equipment you use and your specific needs. Be sure to use an online wattage calculator or consult with a professional to determine the appropriate generator size for your food truck.
