Why people go to Dave
The kind of wiring you’re happy to open the canopy and show your mates.
An off-grid setup lives or dies on the details: fuse sizes, cable runs, where the battery sits and whether the charger is actually set up for it. Dave’s customers keep coming back to the same words. Patient. Neat. Knows what he’s talking about. The photos on this page are his own jobs.
One setup he did is now, in its owner’s words, “officially Moreton Island tested”.

The work
Straight off the job, no filters needed.
Utes, 4WDs, canopies, drawer systems and campers. Every one planned for how that owner uses it.

Services
Everything between the alternator and the fridge.
Whether it’s a first dual battery in a work ute or a full canopy build for a lap of the country, the job starts with a chat about what you run, where you go and how long you stay out.
AGM → LITHIUM
Caravan lithium upgrades
Out with the tired AGMs, in with lithium, and the job done to current regulations. If the old wiring needs attention, Dave sorts that too while he’s in there.
DC-DC / BMS
DC chargers and battery management
REDARC Manager 30, RedVision and DC charger setups, so your battery tops up properly from the alternator and the solar without you thinking about it.
SOLAR IN
Solar panels and inputs
Rooftop panels wired in, plus Anderson solar input points on the tray so you can plug a portable panel in when you’re parked up.
USB / ANDERSON / 12V
Charging points and power outlets
Anderson, USB and cig sockets where you actually need them: rear of the cabin, on the tray, in the canopy. Run the fridge inside, then lift it out and plug in beside the ute.
LED
Canopy, toolbox and light bar wiring
Lighting inside and outside the canopy, toolbox lights run off the new battery, and light bar installs wired cleanly into the system.
DIAGNOSTICS
Fault-finding on existing systems
Van that won’t hold charge? System that keeps blowing a fuse? Dave tracks down what was set up wrong and puts it right.
SHUNT / BLUETOOTH
Monitoring, set up on your phone
Victron shunts so you can see what’s being drawn and what the solar or alternator is putting back, with the apps set up and explained before he leaves.
Twin lithium, charger and busbars, laid out before it goes in
How a job runs
Planned first. Wired once. Explained before he goes.
- 01
Talk it through
What you run, how long you stay off the grid and where things need to be. Dave helps you plan and design the exact setup, even when it’s an involved one.
- 02
Build it properly
Neat cable runs, correct fusing and gear mounted to last. Caravan work done to the current regulations.
- 03
Hand it over
He shows you which apps to use to monitor the system and sets them up with you, so you know what your battery is doing at a glance.
“Dave installed a 100ah slimline lithium redarc DC charger and victron shunt behind my back seat. Anderson, USB and cig socket charging points to the rear of the cabin and anderson solar input and charge point to my tray. I can have my fridge on the backseat then take it out, set it on a table beside my ute and charge off the tray anderson point.”
Then the line that matters: “Now officially Moreton Island tested!!!!!!!”

“Had a Redarc Manager 30 system and an Enerdrive B-TEC 12V 200Ah G2 Lithium Battery as well as a 170w rooftop pannle installed into my 4WD. Dave figured out a lighting solution for inside and outside of the canopy, which ended up amazing. From start to finish, Dave was patient with what I required for my particular setup as it was quite involved. The workmanship was second to none and extremely neat. The whole job exceeded my expectations, and I am stoked with the whole setup and layout. Highly recommended thanks.”
“Contacted Dave to do an upgrade from the AGM batteries to Lithium in our Caravan. Can't express enough how pleased we are with his service. All work was completed to the highest standard, complying with the current regulations. We found him to be extremely professional and knowledgeable, giving great advice and even sorting out the previous wiring which unfortunately needed attention. If you are in need of an Auto Electrician who specialises in Off Grid setups Dave is your man. We have absolutely no hesitation in recommending him. Kerry, Palm Beach, Qld”
“Highly recommend Dave... he was on time, knew what he was talking about and fixed the issue we had with a Jayco Expanda and a Victron system that wasn't quite set up correctly - kept blowing a fuse. Dave rectified the issue efficiently, showed us what apps to use to monitor our system - he even helped set the apps up for us. We are stoked to finally have the van maintaining charge and the system running how it should be. Cannot wait to take the van off-grid - thanks again Dave!”
“Dave is a legend! He helped me plan and design the exact 12v setup I was looking for. His attention to detail and meticulous quality is second to none. I couldn’t recommend him highly enough. Cheers again Dave!”
Already got a system?
Van not holding charge, or something keeps blowing a fuse?
Plenty of Dave’s jobs start with somebody else’s wiring. He finds what wasn’t set up right, fixes it, and leaves the system running how it should.
