What Defines the Smallest Diesel Generator?
Understanding Diesel Generator Sizes
Diesel generators come in a variety of sizes and capacities, typically measured in kilowatts (kW). The size of a generator generally correlates with its power output and physical dimensions. For the purpose of this article, “smallest” refers to both the physical size and the power output, specifically focusing on generators that are compact and provide a lower power capacity suitable for portable or small-scale applications.
Key Specifications to Consider
When determining the smallest diesel generator, several key specifications should be considered:
Power Output: Measured in kilowatts (kW) or kilovolt-amperes (kVA).
Physical Dimensions: The actual size and weight of the generator.
Fuel Efficiency: How efficiently the generator uses diesel fuel.
Noise Level: Measured in decibels (dB), important for residential and portable use.
Portability: Features that make the generator easy to transport, such as wheels and handles.
