Why Choose Ozzy Auto Electrics
Before You Go With The Cheaper Quote.
We get it — price matters. But in the world of off-grid electrics, the cheapest quote almost always becomes the most expensive decision.
⚠️
The Poor Man Pays Twice
Every week, vans roll into our Burpengary workshop with systems that were installed by someone cheaper. Wrong battery sizing. Unconfigured BMS. Undersized cable. Components that don't talk to each other. The money the owner saved on the original install? It goes straight into fixing or completely redoing the system. We see it constantly — and it never gets easier to tell someone their system needs to start again.
01
⚡
2-Day Turnaround — Not 2 Weeks
Most workshops need your van for a week or more. We turn most full off-grid builds around in just 2 days — because we pre-order parts before you arrive and our team works efficiently. Your trip doesn't wait.
02
🔬
Attention To Detail Others Miss
Cable sizing calculated for actual load — not guessed. BMS firmware configured and tested. Every connection torqued and documented. Nothing leaves our workshop untested. The details that get skipped elsewhere are the ones that fail 500km from the nearest town.
03
🎓
Qualified Auto Electricians Only
Every install is carried out by a licensed Queensland auto electrician. Not a solar installer. Not a handyman with a YouTube education. An actual qualified auto sparky who does this every single day.
04
📐
Engineered For Maximum Performance
We don't just fit components — we engineer systems. Every part is specified to work together: the right DCDC for your alternator, the right MPPT for your panels, the right inverter for your load. Everything maximised, nothing random.
05
🤝
After Sales Service That Actually Exists
We stay in contact with our customers long after the install. Got a question from the Kimberley? Call us. Something doesn't look right? We're here. We still talk to clients from years ago — because that's just how we operate.
06
🛡️
Ongoing Warranty With Annual Checks
Our workmanship warranty doesn't expire after 12 months and disappear. It's ongoing — backed by yearly system integrity checks that keep your system performing at peak and your warranty current. No other installer in Brisbane offers this.
