We do not install the system for customers. Although, we do make it super easy for you to do it yourself.

With a custom wiring diagram and illustrated installation guide, you’ll be able to install it with no bother. We’ll also be a phone call away in case you have any questions.

We always recommend getting the system signed off by a professional.

It is impossible to be 100% accurate when it comes to off-grid calculations but we can make some pretty solid assumptions to make our calculations as accurate as possible.

We’ve listed the assumptions we have made to ensure a good margin of error is already built into our calculations so you can trust our off-grid times,

  • Solar panels are only 70% efficient
  • 4 hours of sunlight during the summer months
  • 1.5 hours of sunlight during the winter months
  • Inverters are 90% efficient at converting 12V power into 230V power.
  • Lithium batteries can be safely discharged 100%, deep cycle AGM batteries can be safely discharged 80%.


We are in the middle of writing up a detailed summary of how we calculate your daily usage which we will link here when available.

If there are any appliances you would like us to add, please just let us know.

Once you’ve built your system and requested a final quote we will be in touch within 48 Hours.

You can ammend this quote as many times are you like before we send across secure payment invoice.

Once payment has been made delivery usually takes between 3-5 working days and we will keep you updated on the progress of your order.

While waiting for your system to be delivered we’ll send across your personalised wiring diagram and illustrated installtion guide.

Big things start small

Hi, we are your resident campervan electrics geeks – Alan and Ross!

We started converting vans to change the way we live our life. However, we soon discovered that converting a van into a tiny home was too damn hard. We spent hours in YouTube holes, struggling with decision fatigue.

Two Masters of Engineering degrees and two campervan conversions later, Vunked was formed!

We’re on a mission to simplify campervan conversions, starting with electrics. We want to help more people like you to be free and live out the van-life dream, regardless of your existing electrical knowledge. 

Whether you’re planning your van conversion for the future or getting stuck right in now, we are here to help you with free tools and detailed campervan conversion blogs.
