Power Configurations
There are two ways to bring battery power onto your site: an all-in-one hybrid generator, or a BESS power system built from multiple components. Both cut fuel use and noise compared with running diesel alone. The right one depends on your site's size and how much it's likely to grow.
All-in-One Hybrid Generator
A single unit that combines a diesel engine and a battery in one enclosure. It's the simplest way to bring battery power onto a smaller site, with nothing to connect or set up beyond the generator itself.
- Diesel engine and battery combined in a single enclosure, no assembly required
- Standby output up to 44 kVA hybrid package peak, with battery packs ranging from 20.5 kWh to 28.8 kWh LiFePO4, depending on the model
- Battery carries the load during quieter periods, and the diesel engine tops it up
- Accepts solar input on select models, suited to pairing with up to four solar skids (12-18 kVA model) or integrated roof-mounted panels (19-29 kVA model)
- Suits smaller sites, or sites wanting one product rather than separate parts
BESS Power System
A standalone battery that you connect to a diesel generator, solar, or both, rather than a fixed all-in-one unit. Because the battery, generator, and solar skids are separate products, you can size and scale each one to the site, rather than being limited to a single unit's capacity.
- Standalone 60 kVA / 96 kWh battery, sized and connected to suit your site
- Connects to a diesel generator through the 5m BESS Quick Connect Lead
- Generator or solar recharges the battery as it runs
- Battery carries the load on its own in low-demand periods, and restarts the generator automatically when demand rises or charge runs low
- Scales further than the hybrid units, suited to bigger or growing sites

Applications
Power configurations from United Rentals suit a range of sites and project types:
- Construction sites wanting to cut diesel use and generator runtime without losing reliability
- Major infrastructure projects, including tower crane power, needing continuous and reliable backup
- Remote or off-grid sites combining diesel, battery, and solar where grid connection isn't available
- Workshops and events wanting quieter, lower-emission power
- Site offices, amenities, and lunchrooms requiring stable three-phase power
- Servicing windows, where battery backup keeps a site powered while a generator is offline
- Short-term projects and longer major-project deployments alike, with long-term hire rates available
Solar Power for Site Offices and Lunchrooms
A solar platform is a solar panel array that mounts directly onto a shipping container, site office, or lunchroom, or deploys on the ground when a container isn't available. Instead of needing a separate panel array installation, you use the panel system already suited to your site, and it feeds power straight into a BESS or hybrid generator. That cuts down how much diesel or mains power the site needs to run everyday facilities like lighting, air conditioning, and appliances.
Each platform delivers up to 2.8 kW, and up to twelve can connect to a single BESS for up to 33.6 kW of total renewable input, so capacity can grow as a site's power needs do.
Suited for:
- Site offices, lunchrooms, and amenities blocks wanting reduced mains power reliance
- Sites with or without a container available, using ground-deployed or container-mounted panels
- Remote or off-grid sites wanting to cut diesel use
- Major projects scaling up solar capacity as power needs grow
Project Spotlight
Sydney Data Centre Build
Summary
United Rentals partnered with a Tier 1 Australian construction firm to deliver 24/7 power to a large data centre construction site compound in Sydney, running from November 2025 to August 2026. As the project scope grew to include two additional site compounds, United Rentals implemented a hybrid power solution combining traditional diesel generation with Battery Energy Storage Systems (BESS) and Container Mounted Solar Platforms.
Challenge
The site had substantial and complex power demands: a full site office complex with meeting rooms, lunchrooms, toilets, showers and changerooms, plus 35 air-conditioners, ice machines, and 15 hot water units, with peak demand reaching 400kW per day. Relying on diesel-only generation for this scale and duration would have meant high fuel costs, heavier emissions, more frequent servicing, and greater site disruption, especially once the scope expanded to two extra compounds.
Impact
The hybrid approach delivered major operational and environmental gains across the project. Diesel generator runtime was cut by 83%, dropping from 9,096 hours to just 1,523 hours, which translated into approximately $210,000 in fuel cost savings compared with a conventional diesel-only solution. The solution also reduced CO₂ emissions by 159,894kg, while scheduled servicing fell from 19 services to just 3, significantly minimising site logistics and disruption over the course of the build.
Power Solutions FAQs
A BESS stores power from the grid, solar, or a generator and delivers it exactly when it's needed. Paired with a generator, it charges while the generator runs, supplies power during low-demand periods, and restarts the generator automatically when demand increases or energy levels are low.
A hybrid generator combines a smaller diesel engine and battery in one enclosure, up to 44 kVA hybrid package output. A BESS power system uses a standalone 96 kWh battery connected to a diesel generator and up to 12 Solar Platforms, so it scales further and suits bigger or growing sites.
No. It's built to integrate with a BESS or hybrid generator system rather than run independently, so it works best paired with one of those.
Pairing a generator with battery storage or solar can cut fuel use by up to 80%, reduce emissions by up to 50% compared with diesel alone, and cut noise by up to 90%. These are up to figures and will vary by site and configuration.
Yes. It mounts to a standard 20ft container, cabin, or worksite facility, or can be deployed on the ground, so it suits sites with or without a container on hand.
Both. Long-term hire rates are available alongside standard hire terms, and our team can help size the right hire length and configuration for your project.
