Electrical systems in caravaning is a topic worth careful consideration before setting off. A key element is the proper connection of your trailer to the power supply at the campsite. It’s advisable to equip yourself with appropriate cables that meet safety standards and to consider installing solar panels—an excellent alternative when you don't have access to mains power. Car batteries, as well as those in your trailer, should be regularly charged and maintained. Check out our energy management tips to avoid any unpleasant surprises during your trip.
In caravaning, there are several power sources you can use depending on the available conditions:
Campsite Power Supply (230 V) – The most common solution at campsites that offer electrical hookups. Connecting to mains power allows you to use appliances without worrying about draining your battery. It’s important to have the appropriate cable with the correct specifications (designed for outdoor use, waterproof).
Batteries – A standard component in most trailers and motorhomes. Batteries provide power for low-energy devices (lighting, water pump, etc.). They require regular charging, for example from the campsite power supply or other alternative energy sources.
Solar Panels – Increasingly popular in caravaning, photovoltaic panels offer energy independence, especially when camping away from campsites with power access. They charge batteries using solar energy, which is eco-friendly and free, though dependent on weather conditions.
Power Generator (Generator) – An option for emergency power generation when other sources fail. However, generators are noisy and often require fuel, which can be inconvenient over longer periods.
Batteries – Types and Usage Guidelines
The battery is a key component of the electrical system in your trailer or motorhome. There are several types of batteries used in caravaning:
AGM Batteries (Absorbed Glass Mat) – Popular due to their high performance, resistance to deep discharge, and longer lifespan compared to traditional lead-acid batteries. They are more robust and suitable for frequent use.
Gel Batteries – Equally efficient as AGM batteries, but perform better in lower temperatures, making them a good choice for winter caravaning trips.
Lithium-ion Batteries – The most modern and lightweight, offering very high performance and a long lifespan, but they are also the most expensive. They work well for intensive use and long camping trips away from a power grid.
Remember to take proper care of your batteries – regular charging, avoiding complete discharge, and protecting them from extreme temperatures will extend their lifespan.
Safe Connection to the Campsite Power Supply
Connecting your trailer to the power supply at the campsite is a convenient solution, but it requires proper steps to ensure safety. Before connecting, make sure you have the necessary equipment:
Campsite Extension Cord – A waterproof cable with rubber insulation that ensures safe power supply. A standard cord should be about 25 meters long to easily reach the outlet at the campsite.
Campsite Socket Adapter (CEE) – Standard campsites offer hookups based on CEE connectors. Ensure you have the correct adapter to connect your trailer without issues.
Distribution Boards and Protective Devices – If you use multiple electrical devices in your trailer, consider purchasing a distribution board with overload protection. This will help you avoid overloading the electrical system and prevent failures.
Also, note that some campsites have limits on the maximum current draw (usually from 6A to 16A). Exceeding this limit may cause the power supply to shut off or result in a fault.
How to Optimize Power Consumption in Caravaning?
Even if you have a constant power source, it’s wise to conserve energy to avoid overloading the system and to extend the lifespan of your batteries. Here are a few ways to optimize power consumption:
Use Energy-Efficient Devices – Invest in LED lighting and devices with low power consumption. This is a simple way to reduce energy usage, especially when you’re away from a constant power source.
Charge Management – When you have access to mains electricity, try to fully charge all your devices and batteries. This way, you avoid unexpected discharges later during your trip.
Monitor Energy Consumption – If possible, install a system to monitor the energy usage in your trailer. This will help you better manage your energy and adjust it to current needs.
Adequate power supply in caravaning is key to a comfortable journey. The choice of power source depends on your needs and the conditions under which you travel. Connecting to the campsite power supply is the simplest solution, but solar panels and batteries offer greater independence. Remember to prioritize safety when connecting devices and to regularly service the electrical systems in your trailer.
