Hitting the road for a caravan or camping trip is one of Brisbane’s favourite pastimes. Access Auto Electrics designs and installs solar setups for caravans, 4WD, caravan or camper trailer always has the power you need.

Complete Solar Setups for 4WDs & Campers

Whether you’re planning a weekend camping trip or doing a lap of Australia, a solar setup can keep your vehicle powered at all times.

Access Auto Electrics specialises in installing solar panels on all types of 4WDs, campervans, caravans and trailers. Our 4WD solar installations are designed to power all your creature comforts, even when you’re off the grid.

We design every installation from scratch. We’ll discuss your vehicle, how you like to camp and your on-road requirements. Then, we’ll use quality products from manufacturers we trust to ensure your 4WD, caravan or camper is ready for anything!

Every solar and off-grid camping setup is unique. We recommend contacting us to arrange a short consultation before booking your job. We’ll discuss your needs and recommend solar panels, dual battery setups and accessories that match your vehicle.

  • Dual battery set ups
  • Anderson plugs
  • Towing accessories and REDARC electric brake controller kits

How We Design 4x4 Solar Setups

Solar panels are an affordable way to generate power for your campsite, no matter where you are. But we all set campsites a little differently, so no two solar installations are the same.

The technicians at Access Auto Electrics tailor each of our systems to meet your requirements. Here’s how the process works:

  1. 1
    We discuss your camping style – Do you throw down a swag in the dirt? Do you need power for the ultimate rooftop tent mansion? Are you towing a luxury twin-axle caravan? Tell us how you use your 4WD, caravan or camper, and we’ll figure out how much power you need. That helps us choose the right solar panels, solar regulators and battery systems.
  2. 2
    We create a custom solar setup – Our technicians will create a plan showing everything you need. That includes solar panels, dual batteries, wiring, lights, appliances and the accessories you want.
    We’ll discuss the system with you to make sure it meets your camping needs and fits within your budget.
  3. 3
    We book your installation – Once you’re happy with the plan, you can book an installation and our technicians will take care of the rest! The time it takes to install a complete solar setup for your 4WD or vehicle depends on its complexity. It may only take us a few hours to install solar panels, but it could be a multi-day project if you want a complete off-grid system.

Dual Battery Systems for Your 4WD Solar Setup

Solar panels and deep cycle batteries have made it easier than ever to get power while you’re off the grid. But batteries are heavy, and they can slow you down during everyday driving.

If you own a 4WD, camper or caravan, we can design a solar setup that works with your dual battery system to provide plenty of power out on the trails.

The batteries we choose are based on your budget, the amount of space available and how much power you need. We’ll recommend one of three battery technologies for your solar installation:

  • Lithium batteries – The latest in battery technology, lithium is light, powerful, compact and long-lived. Lithium batteries provide the most power out of all deep cycle battery chemistry, making them perfect for 4WD solar setups.
  • Lead acid batteries – Deep cycle lead acid batteries are simple and affordable. The downside is that they’re bigger and heavier than the alternatives.
  • AGM batteries – AGM batteries are the next step up from lead acid. They last longer, provide more power and are much lighter to carry.

Caravan & Camper Trailer Solar Installation

Solar panels are the perfect addition to any camping vehicle! We often work on 4WDs, but our technicians can also design a system to suit your caravan, campervan or camper trailer.

Campervans and caravans offer plenty of roof space for a solar installation. That’s good, because your caravan probably includes power-hungry features, like cooking appliances. If that’s the case, we can combine solar panels with batteries to ensure you have the power you need.

If a camper trailer is more your style, we can still find room for a solar installation that suits your lifestyle. Camper trailers don’t have the same weight concerns as tow vehicles, so they’re often a good way to bring lots of battery power when you’re camping.

We’ll also make sure that your caravan solar installation matches your tow vehicle. That way, you’ll have plenty of power for your campsite, and for your 4WD when you head out on day trips!

The team at Access Auto Electrics shares your passion for hitting the road and going off grid in your camper or caravan. We install everything from dual battery systems to solar set ups, inverters, DC-DC chargers and off grid electrics that can power your next adventure.

Frequently Asked Questions

What do I need to consider when going off grid with my 4x4, caravan, or camper trailer?

Here are some of the things you should consider when designing an off-grid solar system for your vehicle:

  • The type of vehicle you’re using (e.g. 4WD, caravan, van, camper trailer, etc.)

  • Where you’re going and how long you’ll be off-grid

  • Which appliances you’ll be running

  • Whether you need to charge phones, laptops, drones and other devices

  • How you’ll be charging your dual battery system (e.g. solar panels)

When travelling off grid, always remember to tell other people about your plans, and avoid travelling alone where possible. Camping with a second vehicle can save you from a tricky spot.

Can I still use my existing battery when going off grid?

You can’t use your vehicle’s existing battery for off-grid camping and 4WDing. The existing battery in your car can only be used to start the engine and run small loads, like LED lighting. The battery will flatten quickly if it’s used to power accessories such as fridges and camp lights.

You’ll usually need to invest in a dual-battery system if you need power during an extended trip. A deep cycle dual-battery system is designed to handle large electrical loads without going flat.

Can you recommend and supply my setup for my vehicle?

We can design and supply all the components you need for your 4WD, caravan, camper trailer or any other off-grid vehicle. Your setup is unique to how you use your equipment, so we’ll need to discuss your requirements before we can make a recommendation.

What happens to solar when batteries are full?

The voltage generated by solar panels is no longer stored once your batteries reach 100% charge. This prevents the batteries from becoming overcharged, which can damage the battery or cause a fire.

This process is handled automatically by your solar charge controller. The controller automatically detects the battery’s state of charge and allocates the solar power as required.

How do I choose an inverter for an off grid solar system?

You can choose an inverter by adding up the total power consumption of all the devices you need to run at one time. For example, if you’re running a microwave (1000W), a small TV (100W) and a portable fridge (50W), you need at least a 1150W inverter.

It’s a good idea to choose a larger inverter than you need. In our example above, a 1200W or 1500W inverter would be the best choice.


We generally recommend pure sine wave inverters for most camping vehicles. Pure sine wave inverters are capable of running sensitive electronics, like computers and laptops.

What is the best battery for my set up?

The best battery for your set up depends on how you use your vehicle. Deep cycle AGM batteries offer a good balance of performance and price, while Lithium batteries offer industry-leading performance. Lithium batteries typically pay for themselves in the long run.

You’ll also need to choose batteries that can deliver the power you need. This is based on your electrical loads, how long you plan to spend off-grid, and whether you’re using solar and the alternator to charge your batteries.
