Off-grid touring power setup checklist
Plan the core parts of a caravan or 4WD power system before comparing products.
Start with loads and charging opportunities, then check compatibility across the battery, solar, DC-DC charger, inverter and protective equipment.
Start with the trip
Consider how long you camp without mains power, whether you drive each day, the seasons and regions you travel, and which appliances are essential.
Write down a realistic daily energy budget and reserve for poor weather or unexpected delays.
Plan every charging source
Solar, vehicle charging and mains charging all have different constraints. Check the battery’s approved charging profiles and current limits.
Solar yield varies considerably with season, shade and panel orientation. Vehicle charging may require a compatible DC-DC charger.
Protect and maintain the system
Choose suitable fuses, isolators, cable sizes, ventilation and mounting arrangements. Follow equipment installation manuals and applicable standards.
Label circuits, keep records of installed equipment and inspect for loose or damaged connections as recommended by the manufacturer.
Before you buy: checklist
- Daily Wh budget
- Battery usable capacity and BMS limits
- Solar and regulator compatibility
- Vehicle DC-DC charging plan
- Mains charging compatibility
- Wiring, fusing and isolation
- Safe mounting and ventilation
- Professional review of electrical work
Frequently asked questions
What should I buy first?
Work out your expected energy use and charging opportunities before selecting components.
Can I install the entire system myself?
Some low-voltage tasks may be permitted, but fixed 240V electrical work and certain installations require licensed professionals. Check applicable rules.
