Excellent · 33 Google reviewsBuilt in Witherslack, CumbriaEach one steps up in power, like the Lakeland fells they are named after. Choose by the biggest 230V load you want to run, then by how long you stay off hook-up.
Weekends away and lighter loads
The compact one. Enough 230V for a fridge, lights, laptops and small appliances, with smart charging from the engine, the sun and hook-up.
£3,949inc VAT, with 230Ah battery. £3,429 without.
Longer trips and a bigger inverter
More inverter and more battery for longer stays off hook-up. Room for most single 230V kitchen appliances up to 1,600W.
£4,295inc VAT, with 300Ah battery. £3,649 without.
Gas-free cooking and long stays off-grid
Our most popular size. A MultiPlus-II with 2,400W continuous and 460Ah of lithium, sized for a gas-free van that cooks on induction.
£5,169inc VAT, with 460Ah battery. £4,419 without.
Full-time living and heavy 230V loads
The big one, at 24V. A 5000VA MultiPlus-II for heavy 230V loads, a 24V battery bank, and a converter to keep your 12V kit running.
£6,079inc VAT, with 24V 300Ah battery. £4,995 without.
Prices include VAT and the battery. Solar panels, hook-up inlet and the alternator cable kit are optional, and you can add them when you buy (see options). Every board can be changed to suit your van, and we price the changes before we build.

Everything between the battery and your final circuits, mounted, wired, labelled and routed through trunking.
A lot of the problems we are asked to look at on self-built systems come down to settings. So your board leaves with them entered.
Charge settings for your battery are entered on the inverter/charger, the Orion XS and the solar controller, with the DC-DC input current set to suit your alternator.
The Cerbo GX talks to the battery over CAN with DVCC switched on, so every charger follows the battery’s own limits.
The SmartShunt is set to your battery, and the system is ready to add to your VRM account on the day it goes live.
BS 7671 applies in full to the electrical installation in your van, and Section 721 adds requirements for caravans and motor caravans. A board on its own has no final circuits, so it cannot be given an Electrical Installation Certificate.
We test each board up to and including the consumer units, because no final circuits are connected yet. We inspect it first, then carry out the dead tests that apply at that stage: continuity of protective conductors, insulation resistance and polarity on the board wiring. The 230V side gets the tests in IET Guidance Note 3. The 12V side is inspected to BS EN 1648-2 and Annex A721. Functional testing of the switchgear and the Victron kit comes last. The results go in the crate with the board.
Once the board is fixed in and the final circuits are connected, the complete installation needs initial verification, with dead and live tests. We only issue an Electrical Installation Certificate when we fit the whole system ourselves. If you fit the board yourself, you can book an EICR inspection with us once the van is finished.
Wall board. One flat board that sits close to the van wall. Standard on every system, and the only layout for Scafell Pike.
Compact stack. The same system on panels stacked in a tighter footprint, for under-seat or wardrobe spaces. Add £795 on Catbells and Blencathra, or £1,095 on Helvellyn.
| One 235W solar panel with roof fittings | +£200 |
| Two 235W solar panels with roof fittings | +£350 |
| Hook-up inlet with 10m cable | +£35 |

| DC-DC installation kit (cable, fuse and lugs for the alternator run) | +£130 |
| Helvellyn: 628Ah battery instead of 460Ah | +£280 |
Both routes use the same Victron design and the same bench-tested board. You choose who fits it.
We build, set up and bench test the board. You fix it in and make the final connections.

We design, supply and fit the whole system at our Cumbria workshop, 15 minutes from the M6.

It is a complete Victron system, mounted and wired on a board in our workshop before it reaches you. The inverter/charger, DC-DC charger, solar controller, monitoring, distribution and protection are already connected, labelled and set up. In the van, the work comes down to fixing the board and making the final connections.
Fix the board securely, fit the battery and plug its cables on. The Class T main battery fuse is already on the board, with the battery tails connected to it. If your kit includes an MRBF fuse (12V, batteries up to 200Ah), fit it next to the battery, close to its positive terminal, first. Then connect the alternator feed, the solar cable, the hook-up inlet and your final circuits (sockets, lights, pump and so on). The whole installation then needs initial verification before it is put into use. If you would rather we did all of that, we fit systems at our Cumbria workshop.
No. An EIC covers an installation, and a board on its own has no final circuits. BS 7671 applies in full to the finished van, and Section 721 adds requirements for caravans and motor caravans. We inspect and test the board on the bench, up to and including the consumer units, and send the results with it. We only issue an EIC when we fit the whole system ourselves. If you fit the board yourself, you can book an EICR with us once the van is finished.
Start with the biggest 230V appliance you want to run and how long you stay off hook-up. Catbells suits weekends and small loads, Blencathra longer trips, Helvellyn gas-free cooking on induction, and Scafell Pike full-time living and heavy loads. On a free 30-minute call we check your loads, your alternator and the space you have.
Yes. Common changes are a bigger battery, a different GX screen, extra solar or a compact stacked layout instead of a single wall board. We price any change before we build, and it goes on your drawing.
Yes. The Orion XS detects when the engine is running without an extra wire, so it suits smart alternators. We set its input current to suit your alternator before the board ships.
Yes. Charge settings for your battery are entered on the inverter/charger, DC-DC charger and solar controller. The Cerbo GX is linked to the battery with DVCC switched on, the battery monitor is set to your battery and the system is ready to add to your VRM account.
12 months of VRM support, where we can see your system remotely with your permission and help with settings and faults. You also get lifelong membership of our WhatsApp Community, and direct support from us where it is needed.
Yes, every price on this page includes VAT, and the headline price includes the battery. If you already have a suitable battery, the board alone starts at £3,429. Solar panels, a hook-up inlet and the alternator cable kit are optional extras.
A fitted system covers the wiring of the whole van as well as the board. In our Cumbria workshop, the Compact 1200VA install is from £6,095, including labour of about £2,395, and the Gasless 3kVA install is from £7,895, including labour of about £2,994.
Choose one of the four boards and we build it for your van. Or we can fit the whole system at our Cumbria workshop. Not sure which? Call us and we will check your loads, your alternator and your space.
