What Are the Power Requirements for a Food Truck?

When looking at a generator, you need to consider what specific power requirements you need for your food truck.

Considerations include how many appliances you’ll be running, if you want to run an AC unit for your food truck, and if you need to run items such as lights and themed decor.

According to Apex, a specialty vehicle manufacturer, you need at least 2900 watts of power equipment to run everything in your food truck.

They also point out that there are two different kinds of electric load types, resistive loads and reactive loads.

They state that resistive loads are electronics that take the same amount of power to run as they do to startup, things such as:

• Light bulbs
• Toasters
• Microwave ovens
• Coffee makers.

Reactive loads need more power on the initial startup, but once they begin running, they use less energy. A couple of examples of reactive load electronics are appliances such as:

• Refrigerators
• Blenders
• Air conditioners

Apex includes on their site a handy list of electronics and what their power needs are. Take a look at their list here.

What Features Should You Consider For Food trucks?

Generators have many features. Some fall into the must-have category while others are firmly in the nice to have category but not necessary for operation.

Having features like electric start and dual fuel flexibility can be very helpful especially when you are running a food truck. Having the right generator for food trucks is an absolute necessity.

Generator Types

There are also many different types of generators. According to Food on a Truck, you can choose from a conventional generator or a generator that has an inverter.

1. Conventional generators’ features

• They are your primary generator
• They have a motor and an alternator which are used to produce power
• They need constant RPM, and any fluctuation will affect energy flow to your appliances
• They tend to have a higher amount of power output
• They do run for a more extended amount of time
• You cannot use them and that parallel operation
• These generators are larger and weigh more than inverter generators
• The price tag on conventional generators is also lower

2. Inverter generators’ key features

• They are newer on the market
• They use multiphase power equipment and advanced circuitry
• They are more fuel-efficient
• You can adjust their engine speed based on how much energy your running
• They are generally lighter in weight and is a portable generator.
• They are quieter and with less vibration
• Inverter generators have a decent run time for their size
• The price tag is much higher than conventional generators

Both of these run off either gas, diesel, or propane to produce your energy.

Noise Considerations

Noise level is also a feature to take into consideration. If your generator is too loud, it may be challenging to do business with your customers.

If this is a pressure point for you, you will want to search specifically for generators that run at a low decibel output.

That way, the environment of your food truck is comfortable for both you and your clientele. Some cities are even requiring food trucks to have a specific decibel level.

Make sure you check with yours to see if there are any noise level requirements before you purchase your unit.

Noise level is an important factor you must consider because a loud generator can be a turn-off for your clients.

Energy Efficiency

Energy efficiency is also an essential factor for food trucks. You will want to have a unit that provides you with the most amount of power and will take up the smallest amount of space.

It is space prohibitive to carry extra fuel tanks around, especially when you would rather use your storage space for additional products.

When looking at generators, search for a unit that will give you the max amount of runtime without needing to have backup power/ fuel.

Convenience Features

Dual fuel options are convenient because it gives you the ability to choose between gas and propane depending on your preferences and set up for the day. Propane is a more efficient fuel and is generally less expensive.

If your generator has a carburetor, propane is gentler on the generator’s system. Remote starts are also nice to have for a quick setup. Most electric start generators have a remote option.

Other Factors to Consider

You also need to take into consideration the rules for the state and counties that you plan on operating in. Many states have their own set of rules in regards to generators and what features they need for you to be compliant.

In these areas, if you are not compliant, you can face a hefty fine. On top of a fine, you can also risk getting shut down for the day and not being allowed to operate until you comply.

Before buying your generator, look at its EPA ratings, its CARB ratings, and its emission standards. All of those can be critical factors in your generator choice, especially since many areas have green initiatives in place.

It is best to have all those pieces squared away before you click that buy button.

1. Generator Installation

Another thing to keep into consideration is where you are going to install your generator. If your food truck has a compartment already built-in for storage, you will need to know its exact measurements and ensure that your top pick will fit.

If you do not have a built-in compartment in your truck, you may need to look into modifying space to install your generator

Making sure that your generator is adequately ventilated is also essential not only for the proper functionality of your generator but for the safety of yourself and your customers.

It is wise to make sure that you have your generator installed by a professional.

Professionals can make sure that all of the electrical wirework and mechanics are connected correctly and that the machine will function properly.

Electricians are easy to find, and many have a lot of experience with generator installation. A permit also may be required to install your generator in your food truck. A professional is an excellent resource to lean on to make sure you have all those extra pieces in place too.

An electrician will also be able to give you an idea if the model you are looking at is capable of fulfilling all your requirements in your food truck.

Many will also help you choose the correct model. They will also ensure that you know how to operate it properly and should be able to answer any questions you may have.

2. Generator Maintenance

You will also want to look at if any maintenance needs arise if you need to take your unit to a licensed mechanic who is certified to operate on that particular generator.

It may be prudent to know ahead of time if there are any license dealers in your area to save you on time and additional travel in case any maintenance and service issues arise.

Concession Nation suggests that you make sure you are familiar with the generator’s operating procedures and ensure that everyone who works in your food truck knows how to manage the generator as well correctly.

Improper use can affect the overall performance of the generator and shorten its lifespan. Also, make sure to keep a maintenance schedule and follow the manufacturer’s instructions.

This prolongs the life of your unit and will generally keep your warranty intact. Make sure you thoroughly read and understand a manufacturer’s warranty.

3. Weather Considerations

Remember that your generator is not completely weatherproof. If it is not in a compartment within your food truck, it will need a cover, especially if there is heavy rain.

This way, your vehicle will still function at max power, and you will not have to worry about your unit breaking down on you.

You may want to consider having the unit inside your food truck in a compartment for the weather, safety, and ease of use.

Generators are heavy no matter which model they are and can be challenging to load and unload regularly.

Having a model that you can put into a compartment in your truck and or create a space for may be well worth the price tag.

FAQs

Making a purchase as large and specific as a generator brings a lot of questions. Here are a few FAQ’s

Can The Generator be Fully Enclosed?

Generators need airflow to function correctly. As a general rule, there should be airflow on at least two sides of your generator to prevent overheating and engine failure. This also may void your warranty.

Can I Mount it on My Trailer Tongue?

There are a few different factors to take into consideration. According to Concession Nation, you can secure it to your tongue.

You will need to calculate the added weight to see if you need a heavier-duty support jack.

How Much Oil Will the Generator Need?

Use your dipstick to check your oil levels to give you a better idea of how much oil your model needs.

If your generator does not have a dipstick, there should be a fill like inside the oil tank, which you will see when you take the lid off.

Does the Generator Require a Specific Oil?

According to Concession Nation, you should always consult your user manual for oil specifics.

However, based on operation temperature, they recommend:

• SAE 30 is rated for 40°F and up and is an excellent standard oil
• 10W-30 is better when you have a variable outside temperature, but tends to increase oil consumption
• Synthetic 5W-30 is a decent option for variable temperatures that will not quickly consume oil
• 5W-30 is excellent for use during the winter and comes with a cold start technology as well.

How big of a generator do I need for a food truck?

To run basic equipment like refrigerators, blenders, and microwaves, a food truck requires a least of 3000 watts or 25 amps. If you plan to run numerous appliances, however, a generator with a bit more power, between 4000-7000 watts, is recommended to offer you additional leeway.

How much power does a food truck need?

If a truck has a lot of electrical equipment, it will require a generator with additional power, ranging from 5000 watts to roughly 7000 watts. Getting the correct combination of gas-run and electrical-powered equipment is an excellent way to go about powering a food truck.

Key Takeaways

When choosing your generator for your food truck, make sure you do your homework on what the requirements are for your area.

Also, make a list of all the electronics you need to run to get an exact count of the running watts you will need.

When you get those requirements in place, then you can narrow down your options to those that will make your food truck operation smoother.

Remember that the initial cost of getting a generator for your food truck may seem expensive.

However, it may be far less than the lost revenue you could have if you did not have the proper generator for your food truck, and you had to close up shop.

Always err on the side of caution and choose a model that has more power than you need instead of getting a model that has just enough.
