Often combined with solar is the battery system. Solar energy is used to keep your battery charged. If you don’t have an adequate battery system, all the solar power available wont meet your needs. Many caravans come with one battery, though more and more are now including a second battery. Having just one will always prove difficult for free camping. Common upgrades include adding a second battery, or changing over to lithium batteries, which have the added benefit of being lighter, among several other benefits.
Lithium batteries are in fact about 1/3 the weight of the equivalent AGM battery. They charge faster and last longer as well. Another advantage of Lithium batteries over AGM is they have the ability to be discharges as low as 20% of their amp/hour capacity, compared with 70% for AGM.
Upgrading your solar at the same time as your battery system upgrade is often the best combination for providing the power you need to spend extended time off grid.
These are just a couple of examples of the many upgrades we can do for you at Caravan HQ. You are welcome to call and speak to one of our expert team about any caravan upgrades you might be considering, and whether they will adequately meet your needs.
