From dual batteries and solar to inverters and accessories — we build self-sufficient electrical systems for 4WDs and caravans that handle anything the road throws at them.
Heading bush, crossing the island, or taking on a serious overland trip? Your rig needs to be electrically self-sufficient before you leave the bitumen. Ultra Auto Electrical specialises in off-grid power systems for 4WDs, caravans, and camper trailers — engineered properly, installed cleanly, and built to survive real Australian conditions.
Smart isolator and DC-DC charger installs that protect your starter battery while keeping your auxiliary power fully charged.
MPPT solar controllers, panel mounting, and integrated charging solutions — keep your batteries topped up wherever you park.
Pure sine wave inverter installs so you can run household appliances off your vehicle — camp in comfort, not compromise.
Fridge wiring, UHF radio, satellite comms prep, and accessory mounting — everything for the long haul, done once.
A dodgy install and inferior equipment can leave you stranded hundreds of kilometres from nowhere. We don’t cut corners — every system we build is wired to last, tested before you leave, and matched to how you actually use your vehicle.
