Australia’s weather can be unpredictable—from sudden coastal downpours to tropical storms and morning condensation in the outback. If you’re travelling or camping off-grid with a 12V setup, moisture is one of the biggest threats to your gear’s reliability, safety, and performance.
At All 12 Volt, we’ve seen how water damage can turn a great trip into a frustrating one. So we’ve put together this guide to help you waterproof your 12V system, protect your electronics, and keep your setup running rain or shine.
Water can short-circuit or permanently damage your electronics
Condensation builds up in closed spaces like caravans and battery boxes
Corrosion weakens terminals, wiring, and components over time
Dampness can affect solar connections, inverters, and even LED lights
A single unsealed cable gland or loose connector can lead to expensive repairs.
Use sealed, weather-resistant battery boxes like the ZENOT Extreme Battery Box, designed with:
Rubber gaskets
Watertight cable entry points
UV-stable materials
Tip: Mount boxes above floor level in caravans or vehicles to prevent flood exposure.
Choose Anderson plugs, waterproof DC connectors, and marine-grade terminals. Look for:
IP-rated connectors (IP67 or higher is ideal)
Rubber covers or gaskets
Dielectric grease to prevent corrosion
Also, avoid running cables along floors or low tray channels where water can pool.
Mount fuse blocks and panels in dry, ventilated locations. If outdoors or in a tray:
Use a weatherproof enclosure
Seal cable entries with glands or bushings
Check fuses regularly for corrosion or discolouration
Position solar charge controllers inside the van, canopy, or toolbox. Use:
MPPT controllers with heat and moisture protection
Sealed solar panel junction boxes with silicone grommets
Protective covers on panel MC4 connectors
These should never be exposed to rain or wet surfaces. Use:
Dedicated, dry compartments
Elevated mounting brackets
Cooling ventilation that doesn’t compromise waterproofing
Use cable conduits or split tubing to protect exposed wires
Label and colour-code everything—makes fault finding easier in the rain
Carry electrical tape, heat shrink, and silicone sealant for emergency repairs
Regularly check for green or white corrosion around terminals and plugs
We offer a range of components specifically built for outdoor and harsh environments, including:
Waterproof 12V switches and ports
ZENOT battery boxes
IP-rated solar connectors
Heavy-duty fuses and mounts
