Three tiers of electrical system, matched to your power requirements — then tailored to your van. From loose components to fully-mounted power boards, ready to install.
When someone rings us with no idea where to start, it almost always comes down to the same three questions: how big a battery do I need, how much solar should I run, and do I need an inverter?
Answer those three things, and your system builds itself. The tier you choose — components, pre-wired cables or power board — is purely about how much of the installation work you want to do yourself.
Everyone's van layout is unique. We don't build kits around van models because a Crafter owner building a workshop van needs a completely different system to a Crafter owner going full-time off-grid. What we match is your power requirement. The System Builder handles that in 10 minutes.
All three tiers use the same quality components — the difference is how much of the build we do before it reaches you.
Maximum flexibility. Hardest install.
Flexibility, with time saved.
Quickest and most reliable install.
The components-only tier gives you everything you need to build a fully custom electrical system from scratch. Cable up to 6mm² is supplied loose — you cut to whatever lengths you need. All high-current cables above 6mm² are still cut and terminated by us before dispatch, for safety.
You crimp, route and connect everything else yourself in the van. No compromises on routing, no wasted cable — every run is exactly the length you need it to be.
Experienced builders who know their layout inside out and want full control over every cable run and connection. This is the most time-consuming install, but the result is entirely your own.
Pre-wired cables are exactly what they sound like — every cable in the system is cut to length, terminated, labelled, colour-coded and heatshrunk before it leaves us. You're not starting from scratch. You're connecting a set of clearly-labelled, ready-made cables into your van.
This is the middle tier. You still route cables through your specific van layout, but the preparation work — the cutting, crimping, heatshrinking — is done. You pick up where the bench work ends.
Builders who want a clean, professional finish without spending days at the workbench. Good for first-time builders who are competent with a basic install but don't want to start entirely from raw components.
A power board is a modular, fully-mounted electrical system — every component mounted on boards, one for 12V, one for solar and one for mains, all interconnected. Every connection is made, every label is in place. You connect the board into your van and run the other cables to your lights and loads. That's the install.
There's no wiring to figure out. The system arrives ready. You screw it in, run your battery cables, and connect your solar input and loads.
For builders who want a professional result without the installation complexity — or who simply want the job done right the first time — this is the tier. Particularly suited to larger builds where complexity is high and getting it wrong is expensive.
Builders who want the fastest, most reliable install with the cleanest result. The boards are designed so that any competent person can connect them — no specialist knowledge required.
Answer a few quick questions and we'll point you in the right direction.

130–190W makes a significant difference for everyday use — it'll keep a 100Ah battery in good shape on most days with daylight available. Larger systems with higher daily demand need more. We specify panels for flexible and rigid installations; we don't stock semi-rigid panels. See our full range of solar panels for campervans.
If you want to charge your leisure battery efficiently from your vehicle's alternator — yes. A DC-DC charger (we use the Victron Orion XS range, from our split charge kits) conditions the charge properly, protects your alternator, and is essential for lithium battery systems.
Components only — you do all the cutting, crimping and terminating yourself (except high-current cables which we pre-terminate). Pre-wired cables — cables arrive ready to connect, routing is still down to you. Power boards — the full system arrives mounted and wired across three modular boards; you connect it into the van.
We don't offer van-specific kits because every build is different — two Crafter owners might need completely different systems depending on their usage and layout. What we match is your power requirement, not your van. The System Builder handles this, or read our Campervan Electrics Guide to understand the decisions involved.
All cables above 6mm² — battery to DC-DC charger, 12V fuse box supply cables, heavy alternator feeds, busbar cables — are cut and terminated by us in all three tiers. You never have to crimp high-current connections yourself, regardless of which tier you choose.
It depends on your usage and budget. AGM is a reliable, lower-cost option for most weekend builders. Lithium is the better choice for full-time or high-demand builds — longer lifespan, more usable capacity, lighter weight. See our full range of leisure batteries or use the System Builder to get a recommendation based on your power needs.
We've been doing this since 2012. If you know what you want to run in the van but you're not sure what you need, book a call — we'll work it out with you in a few minutes.
