Turn your diesel fleet into a hybrid power fleet.
Foxtheon EnergyPack pairs with the gensets you already own — helping rental operators win low-emission projects, reduce generator runtime, support quiet-site demand, and create new rental revenue lines.
Hybrid power for rental fleets, not just battery hire.
EnergyPack works as part of a rental-ready power package: genset + BESS + EMS + FoxCloud remote monitoring + project reporting.
Built for rental economics.
Help clients reduce fuel, runtime and noise — while creating a higher-value rental package around existing generator assets.
Diesel-only rental fleets are being asked to do more.
Your clients increasingly ask for quiet, low-emission and measurable power. A diesel-only fleet cannot always answer that demand — but you do not need to scrap it. You need to upgrade it.
Fuel & runtime pressure
Gensets often run 24/7 at low load, wasting fuel, increasing service intervals and shortening useful asset life.
Noise & emissions requirements
Urban sites, night work, events and ESG-led projects increasingly require quieter, lower-emission power solutions.
Commodity rental margins
Hire rates on plain diesel generators are easy to compare. Hybrid power gives rental operators a more valuable package to sell.
Turn generator hire into a hybrid power service.
EnergyPack is designed to work with the diesel generators already in your fleet. It handles low-load periods, peak demand and fast transient loads, while the generator runs fewer and healthier hours.
Protect existing generator assets
Use BESS to reduce unnecessary runtime and help gensets operate in a healthier load range.
Add new rental revenue lines
Package BESS hire, EMS, remote monitoring and emissions reporting as value-added services.
Give clients measurable outcomes
Support fuel-saving reports, generator runtime data, battery operating logs and project-level energy insights.
Standardise a repeatable hybrid SKU
Start with a pilot configuration, validate the economics, then scale the same package across branches and projects.
A rental-ready hybrid power solution — not just a battery.
Foxtheon helps rental companies move from equipment hire to managed hybrid power services.
Win more jobs
Bid for low-emission, quiet-site and ESG-reported projects that diesel-only fleets may struggle to serve.
Protect your assets
Let EnergyPack handle low load and power peaks, so gensets run fewer, healthier and more productive hours.
Create new margin
Add BESS rental, EMS control, remote monitoring and energy reporting on top of traditional genset hire.
Manage every unit
Use FoxCloud and open API capability to monitor assets across sites, branches and rental customers.
High-value applications for power rental operators.
Hybrid power is most valuable where generator oversizing, low-load operation, noise restrictions or remote refuelling costs make diesel-only power inefficient.
Tower cranes & high-surge loads
Support start-up surges and dynamic load swings while reducing unnecessary generator oversizing.
Recommended: P150 / P300 / P500Site compounds & temporary power
Run site offices, lighting, cabins and small tools with quieter battery operation during low-load periods.
Recommended: P150 / M150 / M300Remote camps & off-grid sites
Reduce generator runtime, refuelling trips and maintenance visits where service distance matters.
Recommended: M300 / M600Events & urban quiet power
Provide near-silent temporary power for night work, events, broadcast zones and noise-sensitive environments.
Recommended: P150 / M150Data-centre temporary power
Support mission-critical bridging, temporary load support and fast response power requirements.
Recommended: M300 Pro / M600Fleet standardisation
Build a repeatable hybrid rental SKU that sales teams can quote, deploy and scale across branches.
Recommended: P150 / M300 ProStart small. Scale across your fleet.
Choose a starter unit for measurable pilots, then standardise the configuration into a repeatable rental package.
EnergyPack P150
A compact, rental-friendly hybrid power unit for single-unit trials, tower cranes, site compounds and quiet temporary power.
EnergyPack M300 Pro
A higher-capacity option for larger sites, remote camps, data-centre temporary power and high-value fleet deployment.
One dashboard for hybrid rental assets.
FoxCloud helps rental operators track every EnergyPack unit across customer sites, branches and regions — with operating data that supports service planning and customer reporting.
A practical path for rental fleet adoption.
Start with measurable pilots, validate the operating data, then turn the configuration into a standard offering your sales team can repeat.
Review load profiles
Identify sites with low-load genset runtime, peak load events, noise restrictions or expensive refuelling.
Select starter units
Define a standard P150 or M300 Pro configuration for the first 3–5 measurable pilot projects.
Package the offer
Bundle genset, BESS, EMS, monitoring, commissioning and reporting into a clear rental package.
Scale the SKU
Use verified performance data to train sales teams, quote faster and roll out across branches.
Proven on demanding temporary and off-grid power projects.
The results below are examples from selected projects. Actual savings depend on load profile, generator setup, operating strategy, fuel price and site conditions.
Hybrid power for remote off-grid accommodation.
A rental partner used hybrid power to reduce generator runtime and support a remote site located far from the nearest service centre.
Lower diesel use for crane-heavy temporary power.
A rental owner deployed hybrid power on a tower-crane site to reduce daily fuel use and downsize generator capacity.

Common questions from rental operators.
Do we have to replace our gensets?
No. EnergyPack is designed to work with your existing gensets. It helps reduce runtime, manage low-load operation and support power peaks. Think upgrade, not replacement.
Will BESS reduce our generator rental revenue?
Hybrid power creates a higher-value package around your existing generator assets. Rental operators can add BESS hire, EMS, remote monitoring and reporting as new line items while extending genset asset life.
Which model should a rental company start with?
For many operators, EnergyPack P150 is a practical starter SKU for single-unit trials, site compounds, quiet power and tower-crane support. For larger projects or higher-capacity applications, M300 Pro can be used as a scale-up option.
How hard is it to deploy and move?
P150 is designed with rental logistics in mind, including compact canopy design, quick connection, a single lifting point and forklift pockets. Final deployment requirements depend on project configuration and local regulations.
Can Foxtheon support fleet monitoring and customer reporting?
Yes. FoxCloud provides remote monitoring for operating status, alarms, SOC, runtime and project-level data. Open API capability can also support integration with existing fleet-management systems.
What data is needed for a rental ROI assessment?
The most useful inputs are load profile, generator size, operating hours, fuel consumption, fuel price, refuelling distance, noise restrictions and project duration. Foxtheon can use this information to support a tailored project assessment.
Is it certified for our market?
EnergyPack configurations can be aligned with regional requirements such as CE, IEC 62619, UN 38.3 and applicable grid-code settings. Specific certification status should be confirmed by market and project configuration.
