How to Choose the Right Generator

Total Power Requirements

  • Add up the wattage or amperage for everything you need to run, including motor starting surges, and translate that into the kW or kVA size you need for a generator rental
  • Undersized generators can trip overloads or fail to start high-inrush equipment like compressors and pumps
  • Include startup surge loads in your total, not just running wattage, to avoid nuisance shutdowns

Run Time & Fuel Type

  • Decide how long you need continuous power and whether your site allows for refueling or requires an extended-run fuel tank
  • Diesel generators offer longer run times and durability for extended jobsite use, while portable gas generators are better suited for shorter-term or lighter-duty needs
  • Plan your fuel strategy around run times and refueling logistics, especially for remote sites or 24/7 operation

Site Conditions & Distribution

  • Confirm the generator can sit on level, stable ground with adequate ventilation and clearance from structures
  • If loads are spread across the site, plan for distribution equipment like cables, power distribution panels and transfer switches to reach every load safely
  • Consider noise ordinances and placement near occupied areas so the generator doesn't disrupt work or nearby residents

How long can I expect a generator to run?

How long a generator can run depends on the fuel type and size of the fuel tank. Our diesel generators can run anywhere from 8 to 72 hours on a full tank, while our portable gas generators can run 6 to 12 hours. Our hybrid generators can run up to 100 hours on one tank of fuel. Siempre que un generador se llene con el combustible necesario, puede funcionar durante días.

How much fuel does a generator use?

How much fuel a generator uses varies depending on the generator size and load. The average 10-kilowatt generator will consume a little under a gallon of fuel an hour at full load, while a heavy-duty 200-kilowatt generator will likely consume up to 15 gallons of fuel per hour. Consult a United Rentals representative at your local Scottsdale branch for more information about your generator rental.

¿Qué tamaño de generador necesito?

To determine what size generator to rent, calculate the total wattage you need. Combine the running wattage from all the appliances you need to power, then add the starting watts from the appliance with the highest starting wattage. For example, an air conditioner may require 1,500 watts to run continuously, but it requires an additional 2,000 watts to start, so the total wattage needed for your generator would be 3,500 watts. Ask a representative at your local Scottsdale branch for help determining which generator you need.
