What You Need to Know About Towable Generators

Date: December 5th, 2022

Towable generators are increasingly taking a central position in providing temporary or backup energy on industrial sites. You can get mobile generators that are well-configured to match different applications. For example, Kohler mobile generators can produce power ranging from 20kW to 500kW. They are also configured to match up to eight units for maximum versatility.

When shopping for portable generators, Kohler offers a range of power options from 1.8kW to 12. 3kW. Most portable generators run on diesel, propane, or gasoline. Other units have tri-fuel regulators that allow them to run on various fuels. If you are planning on purchasing a towable generator, here is what you need to know.

Common Types of Towable Generators in the Market

Although there are various portable generator fuels, including propane, gasoline, and diesel, the common type of towable generator is the diesel-powered generator. Besides being the most economical, diesel is generally stable and less flammable. It efficiently takes large loads and has a longer run time than gasoline or LPG.


How to Choose Ideal Towable Generator

When purchasing a towable generator for permanent or temporary backup use, there is much to consider. Here are some of the factors to look out for.


Power Requirements

One of the key factors to consider when purchasing a tow-behind mobile generator is your power requirements. Although many brands of efficiently sized mobile generators exist, understanding your power requirements allows you to choose the most suitable size. Purchasing or renting a generator that is too small or too big for your power needs can pose a challenge.

If your work site has one or two power tools that run simultaneously, a small-sized mobile generator of 1000 to 5500 Watts can efficiently supply the power needed. On the other hand, semi-professional units are ideal for medium-sized job sites requiring multiple power tools running. Most semi-professional units use heavy-duty engines with durable components, unlike small generators.

Professional heavy-duty machines (2500 to 15000 watts) are perfect for complex job sites such as construction sites. They are stable, withstand harsh conditions, and provide longer run times.



Beyond the integration of various technologies to produce more adaptable and efficient towable mobile generators, the need for inventing easy-to-operate generators is evident. With a simple start/stop button, users can operate these machines on the first attempt without the need to read the manuals.

Therefore, it is considered a user-friendly mobile generator that does not need special expertise to operate. A generator with remote controls is the best and the easiest to operate.


Modular Capability

Although starting with a single mobile generator is perfectly ok, it is best to consider a unit that can be paralleled with other generators to form a modular power plant. However, not all mobile generators have the modular capability as a standard feature, hence the need to enquire from the manufacturer or supplier before purchase.

Paralleling is vital in case of an increased power requirement in the future. Rather than purchasing a bigger generator, paralleling allows you to set up a power plant that can meet your power needs. The advantage of purchasing a mobile generator with a modular capability is that the equipment’s reliability is enhanced. Additionally, you do not need to switch off the entire operation during maintenance work. You can work on one unit simultaneously as the other generators are still operating.


Physical Size

Mobile generators come in multiple sizes. However, it pays to determine whether the unit you are purchasing needs to be loaded on a truck or towed. Numerous factors determine the size of a generator, including motor starting, power factor, and voltage. Choosing the most appropriate size is prudent. Also, ensure the generator has all the essential features, including forklift slots, lifting eyes, etc.


Fuel Efficiency

Manufacturers are constantly looking for innovative ways to produce energy-efficient generator models. As a result, the latest mobile generators consume less fuel and have a longer run time than the previous models. However, the market has many mobile generator brands with varied fuel efficiency. You will therefore need to enquire from several manufacturers or suppliers about the fuel consumption of various models to make a sound purchase decision.
