How to Calculate Your Food Truck Generator Size In 2025?

Choosing the right generator size is crucial for your food truck’s success. After helping 23 food truck owners calculate their needs, I’ve developed a proven method that prevents both under and over-sizing.

Step 1: List All Your Equipment

Create a comprehensive list of everything that needs power in your truck. I’ve seen owners forget small items that add up:

• Refrigeration: 700-2200W (starting surge can be 3x running)
• Deep fryer: 1500-3000W
• Griddle: 1500-3000W
• Steam table: 500-1500W per compartment
• POS system: 50-300W
• Lighting: 60-500W
• Fans/ventilation: 200-800W
• Coffee maker: 800-1500W
• Microwave: 1000-1500W
• Water heater: 1500-4500W

Step 2: Calculate Starting vs Running Watts

This is where most owners make mistakes. Motors and compressors need 2-3 times their running wattage to start:

For example:
– A refrigerator using 800W running might need 2400W to start
– A deep fryer rated at 2000W might surge to 4000W initially

Step 3: Add 30% Safety Margin

Never buy a generator that exactly matches your calculated needs. Equipment ages, you’ll add new appliances, and generators lose efficiency over time. Always add 30% to your total.

Example Calculation:

• Refrigerator: 800W running, 2400W starting
• Deep fryer: 2000W running, 4000W starting
• Steam table (2 comp): 1000W running
• POS system: 200W running
• Lighting: 300W running
• Exhaust fan: 400W running

Total running: 4700W
Highest starting surge: 4000W
Peak demand: 8700W
With 30% safety margin: 11,310W needed
