Twelve provides high quality caravan electrical services, 12V upgrades and complete off grid power systems for travellers across Port Macquarie and the Mid North Coast.
Whether you need towing setups, solar power, lithium batteries or help with electrical faults, our team delivers safe, reliable and professionally installed solutions that keep your caravan ready for every journey.
Below are the caravan services we provide. Every setup is completed by qualified auto electricians with a strong focus on quality, safety and long-term performance.
Your car and caravan “talk” to each other via the plugs located on the drawbar of your caravan. These plugs can be any combination of a 7 pin plug, 12 pin plug, grey anderson plug, red anderson plug and a reverse camera plug. Each caravan has its own unique wiring combination depending on the electrical system in the van. Matching the wiring in your vehicle to your caravan is essential to the safety & reliability of your towing set up.
When preparing your vehicle to tow your caravan, you will need to have the correct connections & plugs installed but more importantly, the cable size, fusing and battery isolation relay needs to be carefully considered for each vehicle make & model. Having cable too big for the 12 pin plug can cause it to get hot and melt or alternatively, cable too small can lead to volt drop and a weak charge to the caravan battery.
We want our customers to tow with confidence and that starts with knowing their vehicle has been wired correctly to ensure their caravan brakes and lights are working and that their batteries are being charged and their fridge is cool during long trips.
We can supply and install your towing accessories to all makes and models including European, Hybrid Vehicles and Trucks.
The epitome of safety when towing is the electric braking system. We use and recommend the REDARC Tow Pro Elite system to be installed in your vehicle prior to towing anything over 750kg that is fitted with a braking system. This smart vehicle accessory will ensure you have control at the pedal and smooth braking on all road conditions.
Installation of the electric brake unit is neat, tidy and looks seamless in your vehicle. In fact, most of the installation is “behind the scenes” with just the dial being visible. We can supply and install electric brakes to all makes and models including European, Hybrid vehicles and Trucks.
Set your caravan up with high quality 12V accessories designed for comfort, safety and convenience on the road. We install lighting upgrades, power outlets, USB ports, solar expansion points, starlink, reverse cameras, fans, security systems and more.
All accessories are chosen for reliability and installed to integrate safely with your caravan’s existing electrical system.
We supply and install both AGM and lithium batteries for caravans, depending on your power needs and travel style.
Lithium Batteries or otherwise technically known as Lithium Ion Phosphate Batteries (LiFePO4), are the preferred option for caravans, motorhomes & campers due to their lighter weight, power distribution and overall reliability. Lithium Batteries are highly efficient at charging and discharging with the added benefit of using close to the full capacity of the battery which make them a great alternative to AGM Batteries.
We only use and recommend Lithium Batteries which are IEC 62619 certified for ultimate safety. When choosing a Lithium Battery for your vehicle or caravan, we ensure that your power needs are matched to the battery size and capacity.
AGM Batteries suit lighter power usage and systems which may otherwise be programmed to be used with deep cycle batteries.
All of our installations comply with AS/NZS 3001 Standards.
Our team helps you choose the right battery size and type, then install it with correct protection, ventilation and charging support.
Solar power is one of the best and most cost effective investments for off grid travel. Solar panels provide “free” power by harnessing the sun and charging your batteries to ensure you don’t run out of power. Even when you’ve parked your van up at home or in storage, your solar panels can maintain the health of your battery.
We install fixed and portable solar panels, solar regulators, MPPT chargers and complete solar systems for caravans, campers and motorhomes. Every installation includes system testing and performance checks so your solar setup charges efficiently and keeps your battery bank healthy on the road.
Off grid camping has just got a whole lot better with the addition of an inverter! An inverter will run all of your 240V appliances such as kitchen appliances, microwave, coffee machine, CPAP machines, induction cooktops and more!
A professionally installed inverter can also run your caravan air conditioning unit safely and efficiently. We can integrate the installation of your inverter with the mains power of your caravan for a seamless operation, complete with a compliance certificate.
A DC-DC charger in a caravan ensures your house battery is charged fully, safely, and efficiently by regulating voltage from the vehicle’s alternator—especially important with smart alternators and long cable runs.
The installation of a DC-DC charger in your caravan or camper is a wise investment to ensure the protection of both your starter & house batteries. A DC-DC charger will provide the correct charging profile for your batteries, preventing under or over-charging, and will often include a MPPT solar controller so the alternator and solar charging can work together for faster, more reliable power.
Our off grid packages are designed to suit the usage needs of the customer and are configured to work with the battery management system. This means we can customize a system to suit the way you live on the road without unnecessary products or additional expense.
A simple off grid system would include a battery, charger and solar to run some basic 12V accessories such as lights, a fan and a fridge. This system is a common upgrade for someone who enjoys weekend travel or perhaps someone who is a light power user.
For someone travelling with a family or looking at full time travel whilst enjoying their luxuries, we can bulk out the battery storage, install a bigger charger, add an inverter and some extra solar. This self sufficient system will confidently keep you off grid for days & weeks on end without having to rely on plugging in to mains power.
We undertake our electrical safety inspections in accordance with the requirements and guidelines outlined in the standards of AS/NZS3000 and AS/NZS3001 with a focus on safety and reliability. Every inspection includes a thorough testing procedure and check of the entire electrical system and components used.
Following our inspection, a full and thorough report is provided which can be used in dealership disputes, tribunal or court matters. Our compliance and safety inspections are also a popular service for customers who have recently purchased a vehicle, caravan, camper or motorhome second hand and require the electrical system to be checked prior to use. This also allows the customer to receive a detailed handover of how the system works and how to optimise the system should it not meet their needs.
If you are experiencing a fault or issue with the battery system in your caravan, camper or motorhome, we can efficiently diagnose and repair the issue and get you back on the road enjoying your trip!
Common issues and concerns we see and confidently resolve are:
