Inverters:
Most off grid caravan battery systems operate on a 12-volt direct current (DC) system. while household appliances use 240-volt alternating current (AC). An inverter is essential for converting the 12v DC power from your batteries into 240v AC power for your appliances, making them compatible with your caravan’s electrical system.
12v electricity is ideal for powering many items, including lights, water pumps, or refrigerators.
The 12v DC electricity is converted by an inverter to 240v AC, which is then distributed to the standard house power outlets in your off grid caravan. This entails that you may use electronics, charge appliances, and enjoy power exactly as you would at home.
-
DCDC Chargers:
DCDC chargers are designed to charge your batteries while you’re driving. They provide a convenient way to ensure your batteries are fully charged when you arrive at your off grid camping destination, even if iin cloudy days or minimal sun for solar charging.
Tip: Opt for energy-efficient appliances to reduce power consumption and prolong your off-grid stay. Consider low-wattage devices and appliances designed specifically for caravan use. LED lights, three-way fridges, and other caravan-specific appliances are excellent choices to maximize power efficiency.
How to Prepare Your Caravan or Trailer for Off-Grid Travel?
Setting up an off-grid caravan or camper trailer comes with numerous advantages. Perhaps the most enticing one is the opportunity to extend your stay in remote, breathtaking landscapes with fewer people around.
Additionally, the cost-effectiveness of off-grid travel adds to its appeal. Achieving self-sufficiency and comfort is surprisingly straightforward, often requiring only minor modifications to transition your caravan into an off-grid haven. Sometimes, all it takes is the addition of an extra battery or a solar panel.
What you should consider when preparing any caravan or trailer for off-grid adventures, look below:
Power:
Let’s begin with the most obvious aspect: power. Some travelers are content with powering essential appliances like a fridge and charging devices. While others seek all the conveniences of home, including air conditioning. Naturally, the more electrical devices you have, the greater the power requirement. Regardless of your power needs, having a Battery Management System (BMS) in your off-grid caravan setup is essential.
A BMS efficiently tackle incoming power to charge your caravan or trailer’s batteries, which, in turn, supply power to all your home comforts and devices. Additionally, it provides vital information about your power status, including battery levels, estimated charging time, remaining power duration, and even the amperage generated by your solar panels. Some advanced BMS units can even monitor your water tank levels.
Many modern caravans are pre-equipped for off-grid adventures, often featuring an integrated BMS.
Power Sources:
There are three common methods to charge your caravan or trailer’s batteries through the BMS, and most travelers utilize a combination of these methods while on the road: solar panels, vehicle alternator charging while driving, and mains power.
Solar: Solar panels, whether fixed on your caravan’s roof or portable for trailer setups, are cost-effective and efficient in sun-rich regions like Australia. They serve as a reliable source for powering essential devices during off-grid stays, although reliance on other sources may be necessary during cloudy periods.
Vehicle: You can cleverly tap into your vehicle’s 12V power through the alternator while driving. The BMS (or a separate DC to DC charger) can create an output current to charge and maintain your caravan or trailer’s battery.
Mains Power: This refers to the standard 240V power found in homes or caravan parks. Some travelers charge their batteries at home before embarking on a journey or periodically check into powered caravan sites for recharging.
Batteries
The heart of your power system lies in your batteries, which store the generated electricity. While lithium batteries are top-tier, their cost can be prohibitive for many. However, it’s crucial to acquire the best battery within your budget. Smaller setups with minimal power requirements can often thrive on solar and a single deep cycle battery. For larger power needs, consider investing in a pair of lithium batteries. These batteries provide power to your caravan or trailer’s 12V sockets. For devices requiring 240V power, an inverter serves as an intermediary.
Inverter
An inverter enables you to operate all the appliances you would typically use at home, such as charging laptops, camera batteries, or even using a toaster.
