12 Best Generator for Food Truck 2023 – Mobile Power Solution

The food truck business is an extremely mobile kind of business, and it requires a mobile power solution. Using the trucks’ own power supplied by its battery is not nearly enough or efficient for the business to work.

The best generator for the food truck business is the one that can power all the appliances inside and the fittings outside while maintaining the lowest possible noise levels packed with a big tank. These generators usually run on gasoline, diesel, or propane, and they should have a tank large enough to support all the appliances throughout the working hours.

Bear in mind that not only appliances will need power, but the signboards outside, lighting inside, and decorative lights outside of the truck all need electricity.  If you just started planning a food truck business, have in mind all the appliances you will use based on the type of food you will serve.

You might need an oven, refrigerator, freezer, toaster, fryer, dishwasher, etc. Make a list of all the appliances you might need so you can pick the best generator that will suit your needs.

How to pick the best generator for a food truck?

There are few main things you should have in mind when you’re picking the best generator for a food truck.

Pay attention to these points:

• Generator type
• Starting and working power
• Generator’s size
• Watts/ Amperes
• Noise levels
• Run time
• Emissions
• Installation

Generator type

All portable generators are very much alike. You can differentiate them based on the type of fuel they use.

Based on the type of fuel, generators are split into three groups:

1. Gas generators
2. Propane generators
3. Dual fuel generators

It’s pretty clear what makes them apart, the unique ones are generators with dual-fuel systems, which can use both propane and gas.

Size

Portable generators come in all shapes and sizes. What’s important is that the bigger generator doesn’t mean more power. You can find some pretty compact generators that offer plenty of power, choose them based on the space you have available. But, smaller generators usually mean smaller fuel tanks.

Power

Once you’re done with a list of appliances you will need, it’s time to calculate how much power they will need to run simultaneously. Have in mind that some of them need to run all the time, refrigerator and freezer for example.

Depending on the type of appliance, there are two types of load/power usage:

• reactive
• resistive

Appliances with reactive load need more power to start but consume less when they are running. Appliances with motors are usually the ones with a reactive load.

Appliances with resistive load don’t need a lot of power to start, but they consume a lot more when they are running. These are usually appliances with heating elements like ovens, microwaves, toasters, etc.

Since you will probably be using both of these types in your truck, consider them both when choosing the right amount of power the generator can output.

Watts / Amperes

All appliances should have their power consumption listed on their bottom or in the manual. What may confuse you is that usually the appliances have their power requirements listed in amperes, but the generator’s power output is in watts.

To calculate how much power an appliance needs in watts check the manual of the appliance and see how many volts and amperes it has. Multiply volts by amperes and the result is how much power it needs in watts.

But, how can you calculate the total power needed for all appliances when the consumption may vary from time to time? It’s simple – just calculate the total surge power of all appliances. If the generator matches this sum, you will be safe.

It is recommended, however, that the sum you got is the minimum power output of the generator. Getting the one that has a higher power output is recommended for the long run because some appliances need more power as they age.

Check the generator’s specs to see how much starting and running power they have.

Run time

When you take a look at generators specs, you will see a number with the label run time. This number represents the number of hours the generator can run without stopping. Take this into consideration based on the working hours of your food truck. If you’re working long hours it’s better to pick a generator with less power, but with better run time.

Noise levels

Noise levels depend on the engineering of the engine of the generator. There are no rules here, each has a different noise production, and the only thing you can do is to check its specs to see how loud it will be. For a reference, consider anything below 60 dB pretty quiet.

Emissions

Pay attention to the emissions of the generator. Use a standard generator that uses gas fuel from its own tank, or get an EVAP generator. You can find the emission details in the manual or in the detailed description of the generator.

Generators that have low emissions are better for the environment and for their close surroundings, especially for the people working nearby. Check your area’s emission standards. If an EVAP generator is required in your area and you use a standard one, you may face a pretty large fine, up to $40000.

Installation

The food truck generator must be installed properly. It needs a larger space if you’re going to install it inside, or you can fit it into a trailer or a trunk. Large space is required so it has plenty of air around it to keep itself cool and to have good airflow.

I would recommend that you put it in a separate space, the trunk is a good way to go if it’s spacy. Check the voltage while you’re installing it. Usually, it’s 120 or 240. Also, make sure it’s grounded properly, if you’re not sure how to do it, it would be best that you hire a professional who will do it for you.

Ventilation and airflow

Make sure the airflow is good all around the food truck generator. Take this very seriously, good airflow will give improve the cooling of the generator, and it will prevent poisoning from the exhaust fumes of the people inside.

I would recommend that you hire a professional to install it, just to be safe everything will run properly and everyone around it will be safe.

Professionals will inspect the place where you want it installed, so it doesn’t cause CO poisoning, protect it from going on fire and make sure everything is heat resistant and that is grounded properly. Be sure to have a small fire extinguisher near the generator, just to be safe and to deal with accidents as quickly as you can.

The wattage needed to power a food truck varies depending on the appliances and equipment you have on board. Generally, food trucks require anywhere from 3,000 to 20,000 watts of power. To determine the attage needed for your specific food truck, add up the wattage of each appliance and include a 20% buffer for potential power surges and additional equipment.

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

The size of the generator needed for your food truck depends on your truck’s power requirements. After determining the total wattage needed for your appliances, choose a generator with a power output slightly higher than the calculated wattage to account for power surges and potential expansion.

For example, if your food truck requires 10,000 watts, consider purchasing a generator with a power output of 12,000 to 14,000 watts to ensure you have adequate power for all your equipment.

Are inverter generators better for food trucks?

Inverter generators are often preferred for food trucks because they provide clean and stable power, which is essential for sensitive electronics and appliances. They also tend to be quieter, making them more suitable for public spaces.

How often should I refuel my food truck generator?

The frequency of refueling depends on the generator’s fuel capacity and consumption rate. Always monitor the fuel level and have extra fuel on hand, especially during busy hours.

Is it safe to keep the generator running all day?

Most commercial-grade generators are designed to run for extended periods. However, it’s essential to give them breaks, maintain them regularly, and ensure they’re not overheating.

How can I reduce the noise from my food truck generator?

Consider using a generator with a low decibel rating, placing it on a vibration-dampening mat, or using sound barriers or enclosures to minimize noise.

In conclusion

That concludes my list of the best generators for food trucks you can get right now. I hope you found the generator you like! Be sure to double-check your power requirements and choose the generator you want based on that information!
