Big power, tidy install ⚡
This Adria Matrix 670 DL Supreme has just had a full Victron 24V upgrade here at Fiadh, and it's an absolute beast.
What's gone in:
🔹 2× Fogstar 24V 300Ah lithium batteries
🔹 MultiPlus-II 24/5000/120 inverter-charger
🔹 Lynx Class-T power in 1000 for clean, fused distribution
🔹 2× Orion XS 1400 DC-DC chargers, so the alternator does real work on the drive
🔹 Orion DC-DC converter for the 12V side
🔹 SmartSolar MPPT 75/15 with 2× 120W solar panels
🔹 GX Touch display for the whole system at a glance
🔹 WiFi connection for remote monitoring via Victron VRM
Why we like it:
Everything is mounted on black Buffalo Board, with blue trunking keeping the cable runs neat and protected, plus a master isolator, all in the rear garage. It's solid, easy to service, and it keeps the garage space usable (there's still room for the boots).
The GX Touch tells the story: a hefty 100A+ charge going into the batteries on shore power, with the whole system visible from the habitation area. And with VRM, the owner can check battery state, solar yield and charging from anywhere, whether that's the sofa at home or a campsite in Spain.
A van is only as good as its electrics when you're miles from a hook-up. Planning an upgrade, or want to know what your motorhome could handle? Drop us a message.

🔋 A very useful update for Victron Orion XS owners

Victron’s latest Orion XS firmware v1.15 introduces Emergency Reverse Charging.

If your starter battery is too low to crank the engine, a compatible Orion XS can now temporarily reverse its normal charging direction and charge the starter battery from your leisure battery.

For campervans and motorhomes running large lithium leisure banks, this could be an extremely useful get-you-going feature — without needing a separate starter-battery charger or jump pack.

Currently supported on:
• Orion XS 12/12-50A
• Orion XS 12/12-70A
• Orion XS 1400

It requires the latest Orion XS firmware and VictronConnect v6.43.

Victron also says this is the first of several reverse-charging features planned for the Orion XS range, which could make these chargers even more useful in future installations.

We’ll be testing this ourselves.

Two businesses. One new chapter.

Keltie Campers + Rolyan Designs are now Fiadh Adventure Vehicles.

We're bringing together Rolyan's vehicle design, conversion and fabrication experience with Keltie's specialist off-grid electrical engineering — all under one roof at our workshop in Callander.

Same people. Same experience. A much bigger capability.

From bespoke campervan and adventure vehicle builds to lithium, solar, Victron systems, heating, air conditioning and complete gas-free conversions — Fiadh brings the whole vehicle together.

And we're proud to bring Keltie's position as Scotland's only Victron-approved installer specialising in leisure vehicles into Fiadh.

There's plenty more to come.

Keltie Campers + Rolyan Designs are now Fiadh Adventure Vehicles.

After years of building our businesses independently, we've decided to bring Keltie Campers and Rolyan Designs together under one name.

FIADH ADVENTURE VEHICLES

We'll continue operating from the Rolyan Designs workshop in Callander, bringing the experience, facilities and skills of both businesses together under one roof.

For our existing Keltie and Rolyan customers, we're still the same people you've dealt with before. What's changing is what we can now offer together.

Fiadh combines bespoke vehicle design, conversion and fabrication with specialist off-grid electrical engineering — from complete campervan and adventure vehicle builds to lithium, solar, inverter systems, heating, air conditioning, connectivity and electrical diagnostics.

We're also bringing Keltie's position as Scotland's only Victron-approved installer specialising in leisure vehicles into Fiadh.

Over the coming weeks we'll show you more of the workshop, introduce what we're building and explain where we're taking Fiadh.

There's a certain kind of VW T6 owner who's done everything right with their conversion — quality fitout, pop-top roof, the lot — but the electrics are letting the side down.
That was exactly the situation here. The original lead-acid battery mounted under the seat had started overheating and simply couldn't keep up with demand anymore. Not ideal when you're trying to get away and actually use the thing.
We replaced the underseat battery with a Fogstar Drift 172Ah lithium — a significant step up in usable capacity, and no more heat concerns. The original 30A DC-DC charger was swapped out for a Victron Orion XS 50A, which means the lithium charges properly and efficiently from the engine while driving. We also fitted a new Victron SmartSolar MPPT controller and replaced a faulty flexible solar panel on the pop-top that wasn't performing as it should.
The result is a system that actually matches the quality of the rest of the build. Proper lithium power, a charger that can keep up with it, and solar that works.
As the mat in the back says — ...and Relax.
Based in Callander, Perthshire, we work on campervans and motorhomes right across Scotland. If your electrics aren't keeping up with your adventures, give us a shout.
