OFF-GRID SYSTEMS BUILT PROPERLY

  • Perfect for self-builders, professional converters and anyone looking for a professionally built electrical system. Our bespoke electrical systems arrive fully assembled, professionally wired, labelled and tested—saving hours of planning and wiring while giving you the confidence of a professionally built system.

  • We design and install complete off-grid systems for campervans and motorhomes—covering electrical, solar, battery systems, diesel heating, and water setups. Everything is tailored to how you actually use your van, and installed cleanly, safely, and built to last.

  • Already have a system that isn't performing as it should? We upgrade and rebuild campervan and motorhome electrical systems, replacing outdated equipment, improving safety and increasing performance. Whether you need more battery capacity, additional solar, a larger inverter or a complete redesign, we'll build a system you can rely on.

  • Whether you're adding your first panel or upgrading an existing setup, we install high-quality solar systems designed around your energy requirements.

  • Professional installation of diesel heaters to keep your camper comfortable all year round.

  • Fresh and waste water tanks, pumps, pipework, filtration and hot water systems professionally installed.

From bespoke prewired electrical systems for DIY builders to complete installations and upgrades, we design reliable off-grid systems for campervans and motorhomes that are built to last.

LETS TALK ABOUT YOUR PROJECT

BUILT PROPERLY.
NO SHORTCUTS.

Off-Grid Systems is run by Adrian, focusing on building clean, reliable off-grid systems for campervans and motorhomes.

With over 10 years of experience as an electrical engineer, Adrian takes a practical, engineering-led approach to every project. Each system is designed around how you actually use your vehicle—whether that’s a full off-grid setup or a more focused electrical, heating, or water install.

Adrian has hands-on experience building and upgrading off-grid vehicles, including a full electrical and solar retrofit on a classic VW T2, bringing it up to a modern off-grid standard. Work is now underway on a fully off-grid VW LT build, designed for long-term, real-world use. You may even catch a glimpse of it when dropping your vehicle off.

The goal is simple: build systems that are safe, reliable, and built to last.
