How to determine the power you need for a generator

Choosing the right generator begins with understanding the total power required by the equipment you will run. Identify the place of use and the devices that will operate at the same time, then consider both continuous power and the extra power needed at start-up.

Calculate power requirements accurately

Motor-driven equipment can draw more power when it starts. Instead of simply adding the rating labels, allow for starting current too. If you are unsure, share your use case and equipment list with our headquarters team for guidance.

Fuel and running time matter too

Petrol or inverter models can suit short-term portable use, while diesel options may be better for longer running times and higher power requirements. Compare technical details on product pages to make your decision with confidence.
