Absolutely stoked with the 12V setup Kody did for us at Voltaic Welshpool! The workmanship is next level, everything is incredibly neat, well thought out and finished to such a high standard.

Kody handled everything from organising the setup to problem solving any issues that came up, and nothing was ever too much trouble. He genuinely went above and beyond, even tidying up and reorganising existing cords and wiring that weren’t part of the job just to make the whole setup look clean and professional.

You can tell Kody takes a huge amount of pride in his work and his attention to detail is unreal. Couldn’t recommend him highly enough and we’ll 100% be going back for any future 12V work!

I recently had Voltaic install a dual battery system, additional Anderson plugs, and a UHF radio in my vehicle, and I couldn't be happier with the result.

From start to finish, the team was professional, knowledgeable, and incredibly thorough. What really stood out was their communication throughout the entire process. They took the time to confirm every detail before proceeding, ensuring the installation was completed exactly the way I wanted it. That level of care and attention to detail gave me complete confidence that my vehicle was in good hands.

The quality of the workmanship is outstanding. Everything has been installed neatly, professionally, and functions perfectly. It's clear that the team takes great pride in their work and genuinely cares about customer satisfaction.

A special shout-out to Jaimee and Harry. Your customer service, expertise, and commitment to getting everything right made the experience exceptional. You both went above and beyond, and it was a pleasure dealing with you.

If you're looking for a reliable and professional auto electrical company, I highly recommend Voltaic. I'll definitely be returning for any future auto electrical work.

Thanks again, Jaimee, Harry, and the entire Voltaic team for a fantastic job!

I had Max work on both a 1988 Jaguar and a 1983 Land Rover - 1980s British Car Electrics being what they are it wasn’t simple and Max stuck to it and did a great job

Massive thanks to the team at Voltaic Auto Electrical for the outstanding work on my 2025 Hilux.
I had a full canopy dual battery setup installed including a REDARC Alpha 50 system, lighting, Starlink hard wiring, rear work lights, switches, battery trays and more. From start to finish the communication, workmanship and attention to detail were top notch.
Anthony and the crew treated the build like it was their own vehicle. They called during the install with smart suggestions that genuinely improved the setup instead of just rushing the job. The rear canopy lighting, wiring layout, carpet board, battery mounting and overall finish came out absolutely mint.
Everything was done properly:
clean wiring
quality cable and protection
neat layout
factory-looking finish
tested and explained properly on pickup
You can tell these guys take pride in their work and don’t cut corners.
Couldn’t be happier with the final result and I’d happily recommend Voltaic to anyone wanting a quality touring, camping or 4WD electrical setup done right the first time.
Thanks again boys 👍🔥

FAQs

What Is an alcohol interlock device?

An alcohol interlock is a breathalyser that’s fitted to a car or heavy vehicle. It stops the vehicle from starting if alcohol is detected in the driver’s system. While driving, random retests are required to ensure ongoing sobriety. All breath tests and tampering attempts are logged electronically.

Alcohol interlocks can be fitted:

  • Under WA’s Alcohol Interlock Scheme for drink-driving offences
  • Voluntarily by employers for safety in fleet and heavy vehicles
What is the WA Alcohol Interlock Scheme?

The Western Australia Alcohol Interlock Scheme is mandatory for drivers convicted of certain drink-driving offences. Under the scheme:

  • Only vehicles fitted with an approved alcohol interlock can be driven.
  • Compliance is monitored by regular breath tests and data downloads.

On successful program completion, Voltaic Auto Electrical can remove the device, and the Department of Transport will lift the condition from your licence.

 
How long does an alcohol interlock installation take?

Installation usually takes about 3 hours. Drop your car off at 8:30am and we’ll call you when it’s ready.

Can I service my interlock at a different centre?
