A towable diesel generator is a portable, fully integrated power system that allows you to use electricity no matter how off the grid you are. It’s extremely useful in construction sites, especially when there are no electrical outlets nearby, residential outbuildings, outdoor events, and other places where there aren’t typically built-in power sources.
When renting a towable generator, keep in mind factors like power output, fuel type, size, and noise level to make sure you pick the right equipment for your job. Power output, whether it’s single or three-phase, is especially important, because it determines how much wattage the generator can deliver to power your appliances. Check out the FAQs below to learn more.

The cost to rent a towable generator depends on factors such as size, location, and duration of the rental. Contact BigRentz to request a quote so we can find a towable generator that meets your needs.
Generator size corresponds to wattage, or the amount of power it can deliver. A simple way to determine how much wattage you need is to add up the total wattage of everything that will be plugged into the generator, factoring in the starting wattage of your tools.
Keep in mind that a generator can’t run at its maximum capacity, also called surge power, for too long, so you may want to add 10% of the wattage calculation to ensure your generator will have enough power. The wattage of a generator is usually written out as kW (kilowatts) / kVA (kilovolts ampere), the capacity the generator has for power and its actual power output (for example, 20 kW / 25 kVA). There are 1000 watts in a kilowatt.
The length that a diesel generator can run for depends on the size of the fuel tank and the load on the generator. Most diesel generators can last for a full workday, if not slightly longer.
Single-phase and three-phase generators both use alternating currents (ACs) and power cycles to provide power, but single-phase generators only produce one AC flow, while three-phase generators produce and cycle three AC flows simultaneously. Three-phase generators are essentially three single-phase generators housed in one unit, giving them a higher capacity to produce power.
Noise can be a factor when using a generator, especially if you’re renting it for an event like a music festival. Generally, the more power a generator can produce, the louder it’s going to be. A 20 kW / 25 kVA generator typically produces sound levels of around 62 dB, while a 56 kW / 70 kVA generator produces sound levels around 65 dB, and a 120 kW / 150 kVA generator produces sound levels around 66 dB.
For reference, 60 dB is about the same level of noise as a conversation or fan running. 70 dB is about the same as a dishwasher or washing machine running.
