Workshop-built and factory tested. Fit it, connect it, power up.
A complete off-grid electrical panel, built and wired on the bench in our Cumbria workshop; not a box of parts you have to figure out yourself. Every component is mounted, cabled, and fused to spec, ready to slide into your van, cabin, boat or tiny build.
Built around Victron Energy components and tested before it leaves us, so what would normally take days of careful DC wiring becomes a straightforward panel fit.
Select one option from each group. An upgrade replaces the default component—it does not add a second inverter, battery or solar package.
The system arrives mounted, protected, labelled and documented—ready for the final connections in your build.
Pre-wired AC and DC distribution on a single aluminium-backed mounting board
Victron Energy system integration
Circuit protection and isolation devices, correctly rated and fitted
Clearly labelled cabling and terminals throughout
Factory test certificate covering insulation resistance, polarity, torque-checked terminations and RCD trip times, carried out by a qualified electrician before dispatch
Panel wiring diagram, fitting kit and guide
The panel arrives with the hard part already done. Mount it, connect your leisure battery and solar, wire in your appliance circuits, and you’re powered up—without the days normally spent planning and hand-wiring a DC system from scratch.
Every panel is bench-tested in our workshop: insulation resistance, polarity and torque-checked terminations, backed by a factory test certificate that comes with your panel. It’s proof of what left our workshop, not just a claim on a website.
Not assembled from a generic parts list. Designed and built by a team that installs Victron Energy systems every day, to BS 7671 standards.
We’re upfront about this, because it matters for your safety and your paperwork.
The panel itself. Every unit is factory tested and issued with a test certificate covering the workshop build—insulation resistance, polarity and terminations—before it leaves us.
Once the panel is fitted and your AC wiring is connected into your vehicle or building, current UK practice under BS 7671 requires that fixed 230V installations are inspected and certified by a qualified electrician before being energised. This applies to any DIY electrical fit, not just ours—we’d rather tell you now than have it come up later.

A considered Victron-based system with appropriately rated distribution, protection and monitoring.
A pre-wired electrical panel is a complete off-grid electrical system mounted, wired and fused on a single board in our workshop before it ships. Every component is already in position, with cabling sized to its load and fuses rated to spec—you fit the panel and connect your batteries, solar and appliance circuits.
Yes. Every panel is bench-tested in our Cumbria workshop, covering insulation resistance, polarity and terminations, and is issued with a factory test certificate before dispatch.
For the DC side, most confident DIY builders can fit the panel and connect batteries and appliance circuits themselves, following the supplied wiring diagram. For the AC (230V) side, UK practice under BS 7671 requires a qualified electrician to inspect and certify the fixed installation before it’s energised.
The panel is designed to fit standard mounting spaces in common conversion vans, motorhomes and cabin builds. Check the dimensions above against your available space before ordering, or get in touch if you’re not sure.
This product is a fixed-specification panel, built to a standard design and ready to ship. Our bespoke service is designed around your specific system requirements, installation space and project—including full installation if required.
Victron Energy components carry their standard manufacturer warranty. The panel build itself—workshop labour, terminations and fusing—is covered under TBE’s 12-month Workmanship Warranty, which covers the panel as built and tested by us; it doesn’t cover fitting the panel into your project, as that’s carried out by you.
Configure your panel from £4,549.00 and let our workshop take care of the difficult wiring.
