The problem

Dreaming of going off-grid, but overwhelmed by the complexity?

You want the freedom to travel anywhere, but designing a robust electrical system is the most daunting part of any van conversion. Trying to piece it all together from forums and online videos can lead to an unreliable, inefficient, or even unsafe setup.

Mismatched components

Which solar panels are right for which batteries? What size B2B charger do you need? It's easy to make a costly mistake.

Safety concerns

Are you worried about incorrect wiring or fusing? A DIY electrical system can be a fire hazard if not done to professional standards.

Inefficient performance

A system that isn't designed as a whole won't be efficient. You'll lose precious power and won't get the full benefit of your investment.

You have a single point of contact for the entire design, installation, and aftercare process. No dealing with multiple suppliers.

Maximum value & safety

By designing the system as a whole, we ensure there are no weak links, providing better long-term value and total peace of mind.

Completely tailored to you

This isn't a one-size-fits-all kit. Your package is designed from the ground up based on a detailed audit of your personal power needs.

How it works

Our bespoke design & installation process

We create your perfect power system in five clear steps, ensuring a comprehensive result that is perfectly tailored to you.

01

Deep-dive power audit

This is the crucial first step. We conduct a thorough consultation to understand exactly how you use your van and what you need to power. This data forms the blueprint for your comprehensive electrical system — there is no one-size-fits-all package.

02

Bespoke system design & quote

We design your tailored end-to-end package — lithium, solar, B2B and everything in between — and provide a detailed, itemised quote that explains every component and why it has been chosen for your specific needs. Usually returned within 48 hours, with realistic part lead times.

03

Book your installation

A deposit covers the major components for your bespoke system and secures your installation date. Most full-package builds are scheduled within 2–4 weeks, with everything coordinated end-to-end for a seamless experience from start to finish.

04

Single-visit installation

We schedule a time for you to bring your van to our Williton workshop and carry out the complete installation of all components in one seamless, professional process. Most full packages are completed in 1–3 days; for some larger projects we may need to come to you.

05

System handover & education

We give you a comprehensive walkthrough of your new electrical system, explain how everything works together, and hand over all the documentation you need. Our work is covered by a 12-month warranty, with ongoing support whenever you need it.
