Getting a 4wd 12v electrical setup for the first time? Here are some insights that can help you out:

If you’re going to use your four-wheel drive for off-road adventures, you’re going to need a reliable and abundant source of power for all your electrical gear. These days there are more electrical power options than ever before.

Relying on your vehicle’s 12V starting battery to power all of this equipment is a recipe for disaster, and you could find yourself stuck in the scrub after just one night of camping, with a battery that doesn’t have enough voltage left to fire up your 4×4’s engine.

These days there are several power solutions on the market to keep all of your equipment running and charged while leaving your vehicle’s starting battery alone so it can perform its primary function; starting your vehicle’s engine.

Dual Battery Systems

Not so long ago the only viable option for powering accessories was to fit a vehicle with a dual battery system. In its entirety, a dual battery system consists of the vehicle’s charging system (alternator), the starting battery, an auxiliary battery, a battery tray or battery box, a wiring loom, and a battery isolator.

The auxiliary battery would more often than not be a deep cycle battery, designed to provide a consistent level of power over a longer duration than a starting battery, which is designed to provide short bursts of high power for starting an engine.

There are several types of deep cycle batteries; Absorbed Glass Mat (AGM) batteries have glass-mat separators, which help keep the active material on the plates and prevent damage from vibration, and the plates in a Gel battery are held securely in an immobilized gel.

For those without much space in their vehicles (and who have a big budget), lithium iron phosphate (LiFePO4) batteries are a great option. They are about half the size of an equivalent lead-acid battery, up to 30 percent lighter, and have a lifespan up to 10 times as long.

The isolator is designed to ensure accessories draw power from the auxiliary battery, leaving enough charge in the starting battery to fire up the engine when required. In its most basic form, the isolator is a manually operated switch, while automatically switching isolators use a switching solenoid, a blocking diode, or a microprocessor control system.

Modern automotive electrical systems and battery technology have become far more complex than they once were, so an additional component, a DC to DC charger, has to be added to a dual battery system on modern vehicles to ensure correct battery charging.

Solar Power

These days there are a number of affordable solar panel options on the market for 4×4 travellers.

The most basic fixed solar panels can be permanently mounted to vehicles or trailers, so they’re always there when you need them.

Many portable solar panels have a foldout design, to make them compact when not in use and to maximise surface area when in use. Adjustable legs mean they are angled towards the sun for peak efficiency.

Solar Blankets

take up even less space when folded, and as they don’t have a hard frame around their built-in solar panels they can be safely laid out on a vehicle’s roof, windscreen, or bonnet without fear of damaging bodywork.

No matter what style of solar panel you opt for, it will need to be equipped with a regulator to safely charge your vehicle’s battery, smart battery box or power pack. Some panels will come standard with a built-in regulator but others won’t, so keep an eye out. You’ll also need an adequate length cable with Anderson plugs to cover the distance between the solar panel and the battery you need to charge.
