Fast, Reliable Power from 2kVA to 300kVA
Need reliable generator hire Australia-wide, from Sydney to Melbourne, Brisbane and Adelaide? Opt Hire supplies generators for rent across NSW, VIC, SA and QLD, with power solutions from 2kVA to 300kVA across diesel, petrol, solar hybrid and battery systems. Whether you need short-term generator rental or long-term support, we make it easy to get the right setup on site fast.
Power on demand, no matter the job. From small events to major construction sites, our hire fleet of generators keeps you running when it matters most.
Diesel Generator Sizes Available
Choose diesel generator hire when you need dependable, long-running power for construction, industrial work, backup power or sites where grid access is unreliable. Diesel remains the workhorse for heavy-duty output and is often the most cost-effective option over longer operating periods. Opt Hire’s diesel range is ideal for projects where downtime isn’t an option.
Our diesel generator hire fleet covers the most in-demand sizes for temporary power, site builds and commercial applications. We supply everything from 10kVA diesel generators for smaller loads right through to 100kVA diesel generator hire solutions for large-scale projects.
For lighter applications like tools and small equipment, hire of 10kVA, 15kVA and 20kVA diesel generator hire is a common solution. For broader site setups, 25kVA and 30kVA diesel generator rental units suit site sheds, amenities and mid-sized construction loads are the go. Larger jobs often require 40kVA, 45kVA, 50kVA, 60kVA or 80kVA diesel generators for hire, while 100kVA diesel generator hire is typically best suited for civil, mining and events where higher capacity is required.
All Opt Hire generator units are selected for durability and reliability, they’re ready to perform in demanding environments.
Sustainability is central to what we do—and one of the key reasons customers choose Opt Hire when they need to hire a generator without relying solely on traditional diesel options.
We provide sustainable power solutions and low-emission generators across diesel, battery/hybrid, portable power stations, battery energy storage and solar-powered systems. Our hybrid and battery range helps reduce fuel use, noise and site emissions while still delivering reliable performance.
