But how much does a 20kW diesel generator cost? And what factors affect the price of a 20kW diesel generator?

In this blog post, we will answer these questions, provide you with some useful tips on how to choose the best 20kW diesel generator for your needs and budget, and at the same time recommend some diesel generators you can go for.

Average Price of a 20kW Diesel Generator

Based on some factors that we will further explain below, the average price of a 20kW diesel generator can range from $5,000 to $16,000, excluding installation and maintenance costs.

Additionally, some of these factors affecting the price of a 20 kW diesel generator include the following:

1. Brand 

Different brands of diesel generators have different reputations, quality, features, and warranties. Some of the most popular and trusted brands of diesel generators are Cummins, Perkins, Generac, Kubota, Yanmar, Mitsubishi, and Isuzu. Generally, the more reputable and established the brand, the higher the price of the generator.

2. Type

There are different types of diesel generators, such as stationary, portable, mobile, and marine. Stationary diesel generators are installed permanently on a concrete pad and connected to the main electrical panel. Portable diesel generators are smaller and lighter and can be moved around easily. Mobile diesel generators are mounted on trailers and can be towed to different locations. Marine diesel generators are designed for use on boats and ships and have special cooling and corrosion-resistant features. The type of diesel generator affects the price as well as the installation and maintenance costs.

3. Power Output

The power output of a diesel generator is measured in kilowatts (kW) or kilovolts (kVA). A 20-kW diesel generator can produce 20 kilowatts of electrical power, which is equivalent to 25 kilovolt-amperes. The power output of a diesel generator determines how many appliances and equipment it can run simultaneously. The higher the power output, the higher the price of the generator.

4. Fuel Consumption

The fuel consumption of a diesel generator is measured in liters per hour (L/h) or gallons per hour (GPH). A 20kW diesel generator can consume between 3 and 6 liters of diesel fuel per hour, depending on the load and environmental conditions. The fuel consumption of a diesel generator affects the operating cost and the environmental impact of the generator. The lower the fuel consumption, the lower the operating cost and the environmental impact of the generator.

5. Features

Different diesel generators have different features, such as sound attenuation, an automatic transfer switch, remote monitoring, voltage regulation, and emission control. Sound attenuation reduces the noise level of the generator. An automatic transfer switch automatically switches the power source from the utility to the generator and vice versa. Remote monitoring allows the user to monitor and control the generator from a distance. Voltage regulation ensures a stable and consistent voltage output. Emission control reduces the amount of harmful gases and particles emitted by the generator. The more features a diesel generator has, the higher the price of the generator.
