Before you leave on your trip, consider how long you want to be away from mains power. The longer you want to stay off grid, the larger your solar system needs to be… including taking enough caravan batteries. If your existing battery does not provide power for more than 20 hours its probably faulty.
Work out what size battery you’ll need like this:
1) Work out how long you’ll be using each appliances per day, then multiply the wattage of each appliance by this running time
2) Add the wattage hours for all appliances together to get your power consumption / needs
3) Convert the total wattage hours to amp hours and work out what size battery you need.
We recommend doubling the battery size to consider a 50% depth of discharge. Call our friendly team on 0415 362 134 for a battery quote that will serve your travelling requirements or book a service online
