Generators Range for Hire

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

Diesel Generator Hire

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.

Solar Generator Sizes Available

Solar Hybird Generator Hire

Choose a solar hybrid generator when reducing fuel use and lowering emissions is a priority, especially on longer-duration or environmentally sensitive projects. Hybrid and solar diesel systems combine renewable energy with reliable backup, making them a strong fit for site sheds, offices, construction compounds and remote locations. They help reduce running costs while delivering quieter, cleaner operation.

Petrol Generator Sizes Available

Petrol Generator Hire

Choose petrol generator hire when you need compact, portable power for smaller loads, trade work or short-term jobs where mobility matters. These units are easy to move and ideal for powering tools and temporary setups without overcommitting to a larger unit.

Battery & Hybrid Generator Sizes Available

Battery & Hybrid Power Hire

Choose battery and hybrid power when you need quieter, more efficient power with better control over your site’s energy use.

These systems are ideal where noise, emissions and fuel efficiency matter—without compromising reliability.

Our range includes portable power stations for smaller setups, along with hybrid battery generators and Battery Energy Storage System (BESS) units for more demanding applications.

BESS stores and distributes power as needed, helping reduce generator run time and improve overall efficiency.

These systems are a strong fit for:

  • Temporary site power and events
  • Off-grid and remote projects
  • Peak shaving and load balancing
  • Emergency and backup power

If you’re looking for a flexible, low-emission alternative to traditional generator rental, battery and hybrid options offer a smarter way to power your site.

Portable Power Sizes Available

Our diesel
generator range

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.
