A 48V battery can be added to a caravan. An integrated 48V platform must be engineered into it.
Across the Australian caravan industry, 48V electrical systems are becoming increasingly common. Manufacturers and buyers are recognising the advantages of higher-voltage power for running modern appliances and spending more time away from powered sites.
But a 48V label does not tell the complete story.
Two caravans can both advertise 48V power while using fundamentally different approaches. One may accommodate a larger battery and inverter within an existing caravan design. The other may be designed around the complete electrical platform from the beginning.
Harvok belongs to the second category.
Every Harvok is engineered around an integrated 48V electric architecture, bringing battery storage, solar generation, tow-vehicle charging, inversion, power management and onboard appliances together as one coordinated platform.
It is not simply a battery upgrade.
It is part of how the caravan is designed.
48V Is Only Part of the Story
Voltage matters—but integration matters just as much.
A conventional caravan is commonly designed around a 12V electrical system, with larger batteries, solar panels, inverters or additional charging equipment added as optional upgrades.
This can provide additional power, but the original caravan may not have been designed around the complete system.
Battery location, enclosure, cable pathways, charging capacity, ventilation, appliance selection, storage and control interfaces may need to be accommodated after the main layout and structure have already been decided.
Harvok started with a different question:
What would a caravan look like if it were engineered around electric power from the outset?
That question influenced more than the battery.
It shaped how the caravan stores, generates, replenishes, converts, manages and uses energy throughout the day.
Added-on power
A power system fitted within an already established caravan design may require compromises around:
- Battery placement
- Interior storage
- Cable routing
- Component locations
- Charging capacity
- Appliance selection
- Weight distribution
- Monitoring and control
- Exposure and protection
- Future servicing
Platform-first power
A system planned from the beginning allows the manufacturer to consider:
- Where the battery will be installed and protected
- How its weight fits into the complete caravan
- How solar, tow charging and external power work together
- How energy reaches high-demand appliances
- Where inverters, controllers and monitoring equipment are positioned
- How the system will be inspected and serviced
- How the electrical architecture interacts with the body and interior
- How owners monitor and control the caravan
This is the difference between installing electrical components and engineering an electrical platform.
Built Around 48V—Not Converted to It
Harvok did not take a finished 12V caravan and replace its battery with a larger 48V unit.
The complete electrical architecture was developed around 48V from the beginning.
This includes:
- 48V lithium battery storage
- Roof-mounted solar
- High-output tow-vehicle charging
- External mains charging
- Victron 48V inverter technology
- Victron SmartSolar control
- REDARC RedVision and Rogue TVMS
- Centralised system monitoring
- Induction cooking
- Compressor refrigeration
- Compatible air-conditioning use
- Household-style appliances
- Lighting, water pumps and everyday electronics
These elements operate as parts of one coordinated system rather than isolated upgrades.
Protected by Australian Innovation Patent 2021100401, Harvok’s power-system technology was developed specifically for use within its all-electric caravans.
The system has since been refined through years of development, testing and real-world owner travel around Australia.
A Battery Designed Into the Caravan
Battery capacity alone does not determine the quality of an off-grid power system.
Where the battery is positioned, how it is enclosed, how its weight is managed and how it connects to the rest of the system are also important.
Harvok’s battery installation is accommodated within a purpose-designed, protected area of the caravan architecture rather than treated as a visibly exposed afterthought.
During normal use, owners do not need to interact with an exposed battery installation. System information and compatible onboard functions can instead be monitored through the caravan’s control interface.
The installation remains accessible to authorised technicians for inspection and servicing.
This approach is intended to provide:
- Protection from routine external exposure
- Deliberate battery placement
- Consideration of weight within the overall caravan design
- Cleaner integration with the interior and storage
- Planned connections to charging and control equipment
- Suitable service access
- Less visible electrical clutter for the owner
Harvok does not claim that the battery itself acts as a structural member of the monocoque body. The advantage is that its location and protection are considered as part of the caravan’s original engineering—not decided after the caravan has already been built.
Protected by a Fundamentally Different Body
Harvok’s electrical platform is paired with its patent-protected, robotically welded aluminium monocoque construction.
Instead of building separate walls and roof sections around a traditional frame using numerous external body joins, Harvok forms and welds its main aluminium shell as one integrated structural body.
This gives the electrical platform a strong, rigid caravan architecture around it.
The two technologies were developed to complement each other:
- The monocoque body creates the structural foundation.
- The 48V platform supplies and manages onboard power.
- The gas-free design reduces reliance on LPG equipment.
- Solar and tow-vehicle charging help replenish stored energy.
- Centralised monitoring gives owners a clearer view of the caravan’s systems.
- The aerodynamic exterior helps shape the complete towing platform.
That is what Harvok means by integration.
It is not one component working alone. It is the construction, electrical system, appliances and customer experience working together.
Why 48V Works More Efficiently
Electrical power is calculated by multiplying voltage by current.
For the same theoretical 3,000-watt demand:
- At 12V, approximately 250 amps are required.
- At 48V, approximately 62.5 amps are required.
Actual systems experience conversion losses and operating variables, but the underlying principle remains: increasing the voltage allows the same power to be delivered using less electrical current.
For an equivalent power demand, a 48V architecture uses approximately one-quarter of the current required by a 12V architecture.
Lower current can help:
- Reduce resistive electrical losses
- Reduce heat generated through cabling
- Support more efficient cable sizing
- Better accommodate high-demand appliances
- Improve the efficiency of power delivery across the system
This is particularly valuable in an all-electric caravan designed to support appliances such as an induction cooktop, microwave, coffee machine and compatible air-conditioning use.
The benefit is not “more electricity for free.” It is a more appropriate electrical architecture for managing modern power demands.
One Platform. Three Ways to Recharge.
An off-grid electrical system is only as useful as its ability to replenish the energy being used.
Harvok’s platform brings together three charging sources.
1. Roof-mounted solar
Solar panels convert available sunlight into stored energy while the caravan is at camp or travelling.
Solar performance depends on the size of the array, season, weather, temperature, shade, panel condition and campsite orientation.
2. Tow-vehicle charging
Harvok supports high-output charging from a compatible tow vehicle while travelling, with charging of up to 1200W depending on the selected configuration and tow vehicle.
This means travel time between destinations can also contribute to replenishing the caravan’s battery.
3. External power
When mains power is available, it can charge the battery and supply the caravan.
The purpose of integration is not to claim that one energy source will always be sufficient. It is to coordinate several sources so owners have greater flexibility throughout their journey.
Gas-Free Living Changes More Than the Kitchen
Harvok caravans are designed around induction cooking and an all-electric power platform without onboard LPG cooking appliances.
For owners, that means:
- No LPG bottles to refill for cooking
- No open gas flame inside the caravan
- No ongoing gas-appliance servicing for systems that are not fitted
- Induction cooking
- A simpler everyday energy system
- More energy replenished through solar and towing
Removing LPG appliances can also remove the need for certain permanent gas-appliance ventilation openings.
Fewer unnecessary external openings can help reduce uncontrolled air movement and potential dust pathways while supporting the caravan’s insulation and climate-control system.
This does not mean a Harvok has no openings or is completely dustproof. Windows, doors, roof hatches, plumbing ventilation, air conditioning and other required fittings remain.
The benefit is a more controlled caravan environment with fewer unnecessary gas-related penetrations.
Designed Around Real Life
The value of an integrated platform is best understood through the way customers use their caravans.
A morning coffee away from mains power.
Breakfast prepared on an induction cooktop.
Battery replenishment while travelling.
Solar working while the caravan is parked at camp.
A refrigerator keeping food cold throughout the journey.
Lighting, television and devices after sunset.
Compatible air-conditioning use when conditions and available capacity allow.
The technology should operate quietly in the background, allowing couples and families to focus on the destination rather than continually managing disconnected systems.
Available power and off-grid duration will always depend on:
- Battery capacity
- Solar availability
- Weather
- Temperature
- Appliance use
- Battery state
- Tow-vehicle charging
- Individual travel habits
There is no responsible fixed promise for how many days every customer can remain off-grid.
The objective is flexibility: matching the power configuration to the way each owner intends to travel.

Not Every 48V Caravan Is Engineered the Same Way
As 48V becomes more common, customers should look beyond the voltage printed on the specification sheet.
Useful questions to ask include:
- Was the caravan designed around 48V from the beginning?
- Where is the battery positioned?
- How is it protected?
- How can it be inspected and serviced?
- Were battery weight and placement considered in the original design?
- How do solar, tow charging and mains charging work together?
- What inverter and solar-control technology is fitted?
- Is there one central monitoring and control system?
- Which appliances are designed to operate from the system?
- Is the caravan genuinely gas-free?
- Which capacities are standard and which are optional upgrades?
- What happens when weather limits solar generation?
- Is there evidence of real owners using the system over extended journeys?
A large battery can create an impressive specification.
A complete platform is demonstrated by the way every component works together.
Integrated Technology From Trusted Partners

The strength of the platform does not come from one logo or component.
It comes from selecting suitable equipment and integrating it into one coordinated caravan.
Built Around the Future of Caravanning
The caravan industry is moving toward larger lithium systems, greater solar capacity and increasingly electric appliances.
For Harvok, this is not a recent response to an emerging trend.
The company developed its caravan around an integrated 48V power-system philosophy, protected by Australian Innovation Patent 2021100401 and refined through years of development, testing and customer travel.
The defining difference is not simply that a Harvok has a 48V battery.
It is that the battery, charging, power conversion, control, appliances, gas-free design and caravan architecture were considered together from day one.
Not retrofitted. Not treated as an isolated option. Built into the thinking behind the complete caravan.
That is the Harvok 48V difference.
Frequently Asked Questions
