Inverters & 230V Systems
Understand how inverters work and how to safely power household appliances while travelling, including inverter sizing, safe installation, common faults and 12V versus 230V efficiency.
Energy Management
Reduce power consumption and maximise battery life with practical guidance on daily usage calculations, appliance draw, off-grid planning, charging while driving and hook-up versus off-grid operation.
Wiring & Installation
A growing collection of wiring references and installation examples, including typical layouts, fuse sizing, cable charts, battery isolators, solar wiring examples and DC-DC charger installs.
Technical Library
Useful reference material including owner’s manuals, wiring diagrams, product manuals, installation instructions, manufacturer documentation and helpful downloads.
Built for Real-World Upgrades
Our aim is to build a practical library of guides, reference information, wiring diagrams and real-world experiences to help owners get the most from their electrical systems.
In time, this section will also include trusted equipment recommendations for solar panels, MPPT charge controllers, lithium batteries, battery monitors, DC-DC chargers, inverters, portable power stations and useful accessories.
Frequently Asked Questions
Answers to the most common questions from Roller Team owners exploring solar and off-grid power.
Why isn’t my solar panel charging?
Common causes include shading, poor panel angle, dirty panels, incorrect controller settings, wiring faults or a battery that is already full or failing.
How long will my battery last?
Battery life depends on capacity, state of health, temperature and how much power you use each day. Monitoring usage is the best way to estimate real off-grid time.
Can I fit lithium batteries?
Usually yes, but the charging system, battery location, protection devices and charger settings all need to be checked for compatibility first.
What size inverter do I need?
Choose an inverter based on the starting and running wattage of the appliances you want to power, with extra headroom for safe operation.
How many solar panels should I install?
That depends on your daily power use, battery capacity, travel style and the seasons you tour in. Weekend touring needs far less than long off-grid stays.
Is a DC-DC charger worth fitting?
For many modern motorhomes, yes. A DC-DC charger can improve charging performance while driving and is especially useful with smart alternators or lithium upgrades.
