FAQs About Power Generation Equipment

Power generation equipment keeps sites running when there's no grid connection, or as backup when there is. Our range spans standby diesel generators, hybrid units that combine battery storage with diesel and solar, and Battery Energy Storage Systems (BESS) that store and deliver power on demand. Choosing the right capacity and power source for your site is key to keeping costs down and avoiding downtime. 

Check out our FAQ section below for guidance, or contact our team directly to discuss your project.

What size generator do I need for my site?

The right size depends on your site's power draw. Our diesel generator range spans standby capacities from 5 kVA to 125 kVA, so let our team know your equipment list and site requirements and we can help match the right capacity to your needs.

What's the difference between a diesel generator and a hybrid generator?

A diesel generator runs on diesel fuel alone. A hybrid generator combines battery storage, inverter technology and diesel generation into a single unit, and can connect to solar platforms, helping reduce fuel use, running noise and generator runtime on site.

What is a Battery Energy Storage System (BESS) and how does it work?

A BESS stores power from the grid, solar or a generator and delivers it when it's needed. Paired with a generator, it can charge while the generator is running, supply power during low-demand periods, and automatically restart the generator when demand increases or energy levels are low.

How much can hybrid power reduce fuel use and noise on site?

Pairing a generator with a BESS can reduce fuel usage by up to 80%, cut emissions by up to 50% compared to diesel-only generators, and reduce noise by up to 90%. Results vary by site and configuration. In an 18-month case study, our hybrid range delivered 75% of one customer's site energy from renewable solar and cut generator runtime by 94%.

Can I hire power equipment for short-term or long-term projects?

Yes. We offer flexible short- and long-term hire, from a single generator for an event through to hybrid and BESS solutions for long-running major projects.

How does delivery work?

We deliver power generation equipment across Australia. Contact our team to confirm availability and delivery timeframes for your site.
