Portable generators

Portable generators are most often used for emergency power or intermittent uses such as camping and onsite trades work. You’ll want your genset to start up right away, even if it hasn’t been ‘fired up’ for a year or more. And you’ll want it to run safely for as long as needed. Let us supply you with a quality new, reconditioned or rebuild, and schedule you a regular maintenance programme that will see it running smoothly whenever you need it.

Standby generators

Standby generators most often are set up to run on mains failure. They stand by to power critical commercial operations, including a company’s computers, and essential people services such as hospitals. To have them cut out could mean a disaster. However, standby gensets can be subject to the harshest treatment, with months or even years of neglect. But when you need your standby genset, you want it to fire up right away and to run smoothly.

Lister Petter builds gensets with this in mind. Everything is designed and tested for durability. They are the first choice where reliability is paramount. Remember – it’s a false economy to skimp on attention for your genset, such as keeping it topped up with diesel, or not doing regular maintenance. We can handle all that for you.


Home generators

In remote areas that have no electricity, for example Great Barrier Island, or Pacific Island resorts, business and communities, the domestic diesel generator is a workhorse that must be reliable.

We supply new, reconditioned and rebuilt home gensets from approximately 5kva upwards, as well as all technical services including maintenance and trouble shooting.
