Don’t want to give up life’s little luxuries on your next caravan trip? If you are accustomed to the creature comforts of home and would to take them on the road with you when you travel, you should look at installing an inverter on your Caravan. But with so many options out there how do you know what size inverter you need to keep all your 240V appliances powered? 

We’re here to offer some suggestions. 

In this post, we are assuming you already have solar panels or battery system installed in your caravan or vehicle. If you haven’t, we suggest also checking out some of our other blog posts and videos here: 4WD & Caravan Electrics Posts

The size of the inverter you will need is dependent on a few factors:
  • The number of appliances you will be powering
  • The type of devices you will be powering
  • The size of your batteries

If you are wanting to run low-draw 240V devices like TVs, laptops and lights, a 300W – 600W size inverter should be enough.

However, if you are looking to run higher powered devices such as kettles, toasters, coffee machines or even Air Conditioning there are a few more things to consider. 

So what are you going to need if you are committed to being completely self-sufficient and avoiding mains power entirely? 

To power these high draw appliances, you will need to ensure you have a large inverter. You will also need a large bank of batteries that have enough capacity to power these devices. A decent set of solar panels is also recommended to keep the batteries charged.

As a minimum for running these high draw appliances, we would suggest a 250Ah 12V battery bank with a 2000W inverter. This would be enough to run most pod coffee machines and some microwaves for a short burst.

If you were wanting to power anything more than this (for example an AC system), you would need to look at a battery bank of at LEAST 300-600Ah and a 3000W inverter.

As you can probably understand the more you want to run on 240V power the bigger, and more expensive, the system gets.

Space and weight are often obstacles when it comes to installing these larger systems in caravans. However, new technologies are constantly being developed to combat this issue. Alternate battery options such as lithium becoming increasingly popular for this reason. There are more options than ever on the market for anyone wanting to be more self-sufficient when travelling. It is important to do plenty of research or consult a professional when considering what is the best solution for you.
