Renogy is the most trusted solar brand for 4WD and caravan use in Australia, and the 100W monocrystalline panel bundled with a 20A MPPT controller is the best starting point for any off-grid setup. The high-efficiency monocrystalline cells perform well in partial shade and low-light conditions, which matters during Australian winters in southern states.
The MPPT controller extracts up to 30% more power from the panel compared to cheaper PWM controllers — a real-world difference when you're relying on solar to run a fridge or lights. The full kit is competitively priced at around $199 and is widely available across Australia.
If you already have a solar panel and need a quality MPPT controller, the Projecta SC110 is the best value option in Australia. It supports AGM, lithium, and gel battery profiles and includes an LCD display for monitoring charge status. Being an Australian brand, you get solid local warranty support and wide availability at Supercheap Auto and Repco.
For anyone who parks their car, boat, or caravan for extended periods, a simple 10W solar trickle charger that plugs into the 12V cigarette socket is a brilliant low-cost solution. It won't fully charge a flat battery, but it keeps a healthy battery topped up indefinitely — preventing the slow discharge that kills batteries left standing for weeks.
