Imagine a bus that runs entirely off solar power—no need for external power connections or compromises on home comforts. That's the innovation we've brought to life with our latest project, transforming a regular vehicle into a fully functional, off-grid home on wheels. This unique solution allows our friends to travel around Australia sustainably, equipped with the conveniences of modern living, such as a normal fridge, television, and air conditioning.
The backbone of this project consists of eight 400-watt solar panels securely affixed to the bus’s roof, generating a total of 3.2 kilowatts. Coupled with 10 kilowatt hours of lithium batteries, this setup ensures a steady energy supply for all onboard electrical devices.
To put that into perspective, the battery capacity could power an electric kettle continuously for five hours. In practical terms, our friends have found these batteries to be sufficient, using only around 20% of their capacity overnight, even in the less sunny autumn months. By midday, the solar system has recharged the batteries back to full strength, ready for another day of travel.
What makes this bus truly remarkable is the intelligent design and user-friendly technology integrated into the system. Inside the bus, the solar panels are wired to a series of isolators, each serving as a checkpoint, monitoring and managing the energy flow from the panels into the batteries.
The Australian-made lithium batteries, known for their durability and long life, are charged through a specialised inverter charge controller. This clever device converts solar energy into a usable form, providing 240-volt power to run the house-like amenities inside the bus without a traditional grid connection.
This setup allows the bus to maintain all the comforts one would expect in a home, but with the freedom to travel anywhere the road might lead. The interior boasts a range of appliances typically found in a household. From a domestic fridge and freezer to a television to an efficient washer-dryer unit—nothing is out of reach.
Heating and cooling needs are met with a four-kilowatt reverse cycle split air conditioning system, sufficient for a generous lounge area. This ensures a comfortable living environment, no matter where the bus is parked.
An essential feature of this design is the ability to monitor energy usage and generation through an app, allowing our friends to keep track of their power consumption effortlessly. This system provides real-time data on how much solar energy is being harnessed and the remaining battery capacity.
Additionally, the bus is equipped with a mobile router, ensuring connectivity as long as mobile reception is available. This means energy data and system status can be checked from anywhere, providing peace of mind on the go.
This project isn't just about outfitting a bus; it's about paving the way for a more sustainable way of travelling and living. It showcases the potential of solar power to provide a full off-grid living experience without sacrificing modern conveniences. With projects like these, more possibilities are becoming accessible for those keen on reducing their carbon footprint while exploring the vastness of Australia.
Next on our agenda is a similar transformation for a 50-foot sailing catamaran, proving that these innovative solutions aren't limited to land-based travel.
Reflecting on this project, it's clear that off-grid living is quickly becoming more viable and desirable. As technology continues to advance, the potential for solar-powered travel and living expands, offering both economic advantages and environmental benefits.
