Caravan 12V Electrical Service in Hobart
A modern caravan runs on its 12V system — lighting, water pumps, fridges, fans, chargers and control panels all depend on clean, well-wired DC power.
We design, install and repair 12V systems on caravans, camper trailers and off-road setups. Every install is neat, fused correctly and built to last through Tasmanian conditions.
What's included
Every 12v electrical job covers
DC-DC charging
Redarc, Victron and similar DC-DC chargers wired for solar and alternator input.
Anderson plugs
Anderson plug installs on vehicle and van for reliable charging on the road.
Isolators & fuses
Correctly rated fuses, isolators and busbars for a safe, tidy system.
Lighting
LED interior and exterior lights, awning lights and reading lights.
Troubleshooting
Diagnosis of flat batteries, dead circuits, blown fuses and dodgy wiring.
Why it matters
Why this service is worth doing properly
- Poorly installed 12V wiring is a leading cause of caravan fires — every joint, fuse and cable size matters.
- Correctly matched DC-DC and solar charging keeps lithium and AGM batteries healthy for years longer.
- A tidy, labelled system is far cheaper to diagnose next time something goes wrong.

FAQs
12V Electrical — your questions
Do you do 240V electrical work?+
No. 240V work must legally be carried out by a licensed electrician. We handle 12V only, and can coordinate with a licensed electrician where needed.
Can you install a lithium battery upgrade?+
Yes. We size the battery, DC-DC charger, cabling and fusing for your setup and install it neatly. We'll also check your existing solar and alternator input works with the new system.
Can you diagnose why my caravan battery keeps going flat?+
Yes. Flat batteries usually come down to parasitic draw, a failing battery, a faulty charger or bad wiring. We'll trace it and quote the fix before doing the work.
