Camping and Caravan Plug-In Solar: The Grey Nomad Kit Shortlist

Australia's Grey Nomad demographic — retirees touring Australia in caravans and camper trailers — is one of the largest portable solar markets in the world. Six months on the Nullarbor, up to Cape York, along the coast: 400W of panels plus 1–2kWh of LiFePO4 battery is the standard kit. Here's what works, what wastes money, and how to size it.

The three deployment styles

1. Roof-mounted rigid (permanent)

200–400W rigid panels bolted to the caravan roof, MC4 to an MPPT charge controller, into the caravan house battery. Always generating when you're outdoors, zero setup at camp. Downside: fixed angle, poor winter output in southern latitudes.

2. Portable folding suitcase (deployed at camp)

120–200W folding kit with kickstand. Set up at camp aimed at the sun, packs away for driving. Better winter output (angle adjustable), doesn't add drag. Downside: manual setup daily, theft target.

3. Hybrid (both)

Roof panels for driving days, portable folding for extended stays. Most touring rigs run this combo.

Sizing for daily loads

Typical caravan loads on tour:

400W of panels in Alice Springs sun generates 1,800–2,400 Wh/day easily. In Melbourne winter drops to 800–1,000. Size battery to 1.5× daily draw for cloudy-day buffer.

What to buy from Amazon AU

Suitcase kits from Renogy, Rich Solar, EcoFlow are all reliable. Avoid ultra-cheap no-name folding panels — they underperform spec by 15–25%.

What NOT to do

• Don't undersize the MPPT charge controller — 30A minimum for 400W of panel
• Don't use PWM — costs you 20% of your generation
• Don't skip fuses — 30A DC fuse on the panel-to-controller run is standard practice
