A modern caravan has basically three electrical systems on board. Two of these systems are 12 volt Direct Current (DC) just like your car and the third is 240 volt Alternating Current (AC) just like your house. The first system is to provide the lights that replicate the road lights on your car.

What wiring do I need to tow a caravan?

Many vehicles come with a 7 pin socket as standard, which for most people is all you need for basic towing. However, if your caravan is fitted with a brake away system, electronic stability control or you want to run a fridge power feed, you will need to replace it with a 12 pin socket.

What kind of battery do I need for a caravan?

One of the best battery options for caravan and campers are Absorbed Glass Mat (AGM) Deep Cycle Batteries which can be recharged when flat (better to keep a constant charging cycle) from Solar Panels or charger and are designed to have power drawn from them over a longer period of time.
