How to find what power generator you need
The Macfarlane Generators Power Calculator helps you estimate the generator size required for your application by calculating power demand, motor starting loads, and electrical conversions such as kVA, kW, amps, and horsepower. Designed for homeowners, tradies, and industrial operators, it provides practical tools and power consumption guides to help you select the right generator with confidence. Whether you're planning backup power, construction site equipment, or large-scale operations, the calculator simplifies generator sizing and power planning.
