OFF-GRID SYSTEMS BUILT PROPERLY
-
Pre-wired 2000W and 3000W electrical systems designed to make DIY installation simpler. Each system is professionally assembled, wired and tested in our workshop, with telephone support available during your installation. Optional upgrades include higher-output DC-DC charging, inverter charging and electric hook-up.
-
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 We upgrade and rebuild campervan and motorhome electrical systems, replacing outdated equipment, improving safety and increasing performance.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 pre-wired electrical systems for DIY builders to complete installations and upgrades, we design reliable off-grid systems for campervans, motorhomes, horseboxes and other conversion vehicles.
PRE-WIRED VEHICLE
ELECTRICAL SYSTEMS
Pre-wired. Compact. Ready for your build.
Our pre-wired electrical systems take the complexity out of vehicle electrics. Each system is professionally assembled and wired before leaving our workshop, giving you a straightforward starting point for your installation.
Suitable for campervans, motorhomes, horseboxes, expedition vehicles and other leisure or conversion vehicles.
Available in 2000W and 3000W versions, combining DC-DC charging, solar charging, fused 12V distribution and 230V power into one compact system
WHY CHOoSE A PRE-WIRED SYSTEM?
Most DIY builders are comfortable fitting equipment and routing cables, but designing and wiring the main electrical system can be one of the more complicated parts of a vehicle conversion.
We take care of the complicated part for you.
Each system is professionally assembled, wired and tested in our workshop before dispatch, saving you time spent planning, wiring and troubleshooting.
You get the confidence of a professionally built electrical system while still being able to complete the rest of your conversion yourself.
Every System Includes:
Professionally assembled and wired
Fully tested before dispatch
Telephone support and installation advice
PRE-WIRED SYSTEMS from £1200
Available in 2000W and 3000W configurations, with optional upgrades.
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.
