Whether you’re out in the middle of nowhere, or powering a demanding construction site, you need a power source you can count on.

Diesel generators are tough, powerful and reliable, delivering prime or backup power no matter your location.

Here, we’ve picked 5 of our best diesel generators and will look at how to decide which one is the perfect fit for your needs.

How To Choose The Best Diesel Generator

From noise level to power output and run time, no two diesel generators are the same.

That’s why it's important to really get to know your requirements before purchasing a diesel generator. 7 key considerations include:

1. How long do I need my generator to run in the event of a blackout?
2. What kVA do I need to power all my equipment?
3. Does my generator need to meet certain noise restrictions?
4. Is easy transportation important?
5. Is fuel efficiency important?
6. Do I need any specific customisations?
7. What warranty and servicing does my supplier provide?
