The most important aspect of creating the perfect campervan electrical design is getting the size right.

But it’s a bit of a minefield.

Here’s just an example of some of the typical questions asked when designing and building a DIY campervan conversion:

  • How many batteries do I need?
  • What type of battery do I need?
  • How much battery do I need to run my fridge?
  • What size inverter do I need?
  • What size solar panels do I need?
  • How should I wire my solar panels to get the most charging capacity from them?
  • What size charge controller do I need?
  • What size wires do I need in my electrical installation?

And the list goes on.

There’s no one size fits all answer. We need to consider many factors:

  • Is our campervan electrical system critical to our lifestyle? 
  • Will we live off grid for days or weeks at a time?
  • Do we have access to reliable charging supply like shore power?
  • Will we use an alternator to charge our batteries and if so, will we drive much?
  • Will we live in the camper during the winter?
  • How much electricity will we use?
  • What kind of budget do we have for the electrical installation?

Again, more questions.

So where do you start in answering all this and sizing your electrical system?
