This guide is built around a simple idea: you don’t need an overcomplicated or expensive electrical system for a self-build campervan to work well. What you do need is a setup that’s thought through, efficient, and suited to how you actually use your van.

This video from Greg Virgoe walks through a 12V electrical system designed specifically for budget self-builds. It uses modern components and current best practice to create a setup that’s reliable, easy to understand, and realistic for people building their own vans without professional installers or endless upgrades.

Greg has been sharing clear, technical campervan information for years, and his content is particularly valuable because it focuses on design logic, not just parts lists. He explains why things are wired a certain way, what matters, and where people often overcomplicate systems unnecessarily. That makes this especially useful if you’re trying to avoid common mistakes or planning your build properly from the start.

This setup is a good example of how newer technology can simplify off-grid electrics rather than make them more confusing. It’s practical, cost-effective, and adaptable — whether you’re building from scratch or rethinking an existing system.

We’ve included this because it aligns with how we approach self-builds at 2BOFFGRID: understand the system, don’t just copy it. Watch the walkthrough, take the principles that apply to your van, and adapt them to suit your real-world needs.
