A dedicated system powers your essential gear without the risk of draining your vehicle's starter battery. It allows you to run a fridge/freezer, LED lights, a compressor, comms equipment, and camp appliances for days, turning your 4WD into a self-sufficient basecamp, far from any power grid.

Absolutely. Our 4WD kits are engineered for toughness. Key components like theIP67-rated DC-DC Chargerare dustproof and waterproof, perfect for under-bonnet mounting. OurLiFePO4 batteriesare far more resistant to vibration and shock than traditional batteries, and all components are selected for their robust build quality to withstand the harsh Australian outback.

While many competent DIYers can install the core components, we strongly recommend that the final connections—especially to your vehicle's alternator and starter battery—be done by a qualifiedauto-electrician. This ensures the system is safe, reliable, and doesn't void your vehicle's warranty. Proper installation is critical for managing high currents and ensuring correct grounding.

Yes. Our DC-DC Chargers are specifically designed to work with modern vehicles that have variable-output "smart" alternators. They draw power intelligently to charge your auxiliary batteries efficiently without causing error codes or damaging the vehicle's electrical system.

It depends on your gear and trip length. A200Ah+ kitis ideal for running a fridge and lights over a long weekend. For week-long+ expeditions or if you're powering a winch, a powerful compressor, or a 230V appliance, a300Ah or 400Ah+ kitis recommended. Use our online power calculators or consult with our experts to size your system correctly.

Yes. Our DC-DC Chargers with MPPT (30A, 40A, 50A) are specifically designed to work witYes, and this is a key benefit. TheDC-DC Chargerwill replenish your auxiliary batteries from the alternator while you drive. Simultaneously, thesolar panelson your roof can be charging the system. Theinvertercan also be used to power 230V devices on the move (e.g., charging camera batteries).

h modern vehicles equipped with smart alternators. They intelligently manage the charge profile to safely and efficiently charge your caravan's lithium batteries without damaging your vehicle's electrical system.

For serious off-roading, it's highly recommended. It acts as your system's "fuel gauge," showing your exact State of Charge (SOC%) in real-time on your phone. This prevents you from unexpectedly running out of power in a remote location, allowing you to manage your energy consumption proactively.

Yes. Our Renogy LiFePO4 batteries have a comprehensive Built-in Battery Management System (BMS) that provides protection against over-temperature, over-charge, over-discharge, and short circuits. They operate reliably within a wide temperature range, but the BMS will intervene to protect the battery if safe limits are exceeded.

Yes, our kits are designed to be scalable. You can easily add more Renogy LiFePO4 batteries in parallel to increase capacity. You can also add more solar panels, as long as you stay within the maximum input limits of the DC-DC Charger with MPPT.
