Hello from Wales — converting a Transit

Been lurking for ages and finally decided to stop being shy. I'm based in South Wales and just picked up a 2008 Transit van—bit of a project, but the shell's solid which is what matters.

Planning to convert it into a proper off-grid capable campervan for extended trips, ideally hitting some of the quieter stretches along the Pembrokeshire coast and inland. The goal is to get genuinely self-sufficient rather than relying on hookups all the time.

Currently scoping out the electrical setup—thinking Victron for the core bits (their stuff seems to be the standard round here) but still weighing up battery options. LiFePO₄ looks sensible for weight and longevity, though the initial cost is eye-watering. Anyone gone with cheaper lead-acid and regretted it?

Also considering a small roof-mounted solar array plus a decent alternator upgrade. The van's got a decent roof profile so I've got room to work with, but I'm keen to avoid overcomplicating things.

The narrowboat community has taught me quite a bit about managing power in compact spaces, so I'm not coming in completely blind—but vans are a different beast entirely. Suspect I'll be asking plenty of daft questions as I go.

Would be brilliant to connect with anyone else doing Transit conversions, particularly if you've got experience with Welsh weather and charging reliability. What usually catches people out?

Nice one, welcome aboard! South Wales is brilliant for solar if you're planning that route—decent south-facing aspect possible without too much tree cover in most spots.

What's your power budget looking like? That'll shape everything else. I'm running a similar setup in my van conversion and made the mistake of undersizing my battery bank initially—absolute nightmare in winter when you're getting 2-3 hours of decent sun.

Are you planning to keep it parked in one spot mostly, or going fully nomadic? Makes a difference with the solar array design. Also, what's your timeline like? I see a lot of people rushing the electrical install and regretting it later.

The Transit platform is solid for this—plenty of space for a decent lithium setup if the budget stretches. Have you looked at Victron kit yet, or still in the research phase?

@DodgyCaptain — solid choice on the Transit shell; that's honestly half the battle. Before you dive into spec'ing kit, I'd nail down your actual usage pattern first. Are you planning full-time living, weekends only, or just emergency backup? Makes a massive difference to whether you go lithium or LiFePO₄, and how much battery capacity you're realistically looking at.

One thing folks often overlook in vans: thermal management is harder than in static setups. You'll lose efficiency faster with temperature swings, so factor that into your solar calcs. I run a hybrid setup in my garden office and the lessons transfer directly.

What's your rough timeline? If you're not rushing, worth waiting to see what Fogstar and Renogy release over the next few months—prices shift seasonally. Also, the Welsh weather means your "decent south-facing" angle matters less than people think; diffuse gain becomes your friend November through February.

Feel free to post your rough plan once you've sketched it out. This community's good at catching assumptions early.

@DodgyCaptain — welcome aboard. Transit's a sensible starting point; you'll find plenty of documentation online for weight distribution and water ingress points to watch.

Few practical things before you spec the solar: establish your actual power consumption first. Most people overestimate—a kill-a-watt meter on your planned loads (fridge, heating, lighting, devices) over a week will give you real figures rather than guesses. Then size your battery bank around that, not the other way round.

The 2008 chassis should handle a decent lithium setup without weight concerns, though you'll want to check your carrying capacity documentation. If you're planning stationary mooring in Wales, grid tie might actually be worth exploring depending on your location.

Have a look through the narrowboat threads here—similar battery/solar challenges, different context. Several members have done Transit conversions too; search "Transit leisure battery" and you'll find the build logs.

What's your rough timeline and primary use case? That'll determine whether lithium makes sense versus LiFePO₄.

@DodgyCaptain welcome mate. Transit's a solid platform—I've got a static caravan setup myself so won't pretend to be an expert on the van side, but I've picked up a fair bit through the forum.

One thing I'd genuinely suggest before you get too deep: map out your actual power demands first. Sounds obvious, but loads of people spec a massive battery bank and then realise they're only using a fraction. If you're planning to wild camp mostly, heating and hot water will be your biggest drain by miles.

Given you're in South Wales, @LisaStewart71's spot on about solar potential—south-facing roof real estate on a Transit is decent. Victron gear's pricey but bombproof if budget allows; Renogy's solid for a tighter build.

What's your rough timeline, and are you planning to do the electrical work yourself? That'll shape what people can actually help with here.

Transit van conversions are basically just expensive ways to discover you can't actually live without a proper shower — looking forward to your inevitable upgrade to a static in three years mate.

On the serious side though, you're in a decent spot for off-grid kit in South Wales — decent solar potential if you're not perpetually under cloud cover (which, let's be honest, you probably are). Weight distribution's going to be your actual nightmare; those batteries and a decent MPPT controller add up quick.

What's your power budget looking like? If you're running EV charging on-site as well as the van itself, you might want to think bigger than the usual 100Ah lithium setup people default to. Victron gear's overkill for a van but their documentation is chef's kiss if you're learning as you go.

Also mate — 2008 shell means you've got some corrosion risk on the underside depending on how it's been stored. Might be worth sorting that before the electrics go in, otherwise you'll be chasing damp gremlins for the next five years.

@DodgyCaptain brilliant to have you aboard. Transit's a proper workhorse—you've picked a good platform.

South Wales is ideal for off-grid thinking too, especially if you're planning to park up anywhere semi-permanently. I'm curious what your power setup's going to look like? A lot of van converters underestimate their winter energy needs, particularly in Wales where you'll get fewer peak sun hours.

Are you thinking leisure battery + solar, or hybrid approach? I ask because I've been wrestling with similar decisions for my own project, and the Welsh weather's been a real education. If you're planning to use it year-round rather than just summer jaunts, that changes everything.

What's your timeline looking like? The shell being solid is genuinely half the battle—so many people spend ages chasing rust issues instead of getting to the fun electrical side.

Happy to chat through any specifics if you get stuck. We've got a good bunch of people here who've done Transit conversions, so don't hesitate asking questions as you progress.

Good shout on the Transit — 2008s have decent bones and parts availability is still reasonable. South Wales gives you decent sun exposure too, which'll help if you're thinking solar.

The shower thing @SussexSolar mentions is real, but solvable. I've got a narrowboat setup and went through similar grief before settling on a decent 40L hot water tank with a small immersion heater. Takes planning but beats the alternative.

What's your power plan looking like? If you're doing any time stationary, a basic Victron MPPT with a few hundred watts of panels takes the edge off battery drain. Fogstar make solid compact panels that fit awkward spaces on a van roof. Narrowboat regs are different to vans obviously, but the battery maths is much the same.

How long are you planning to be remote for? That'll shape whether you go lithium or stick with lead-acid — different beasts entirely depending on your use case.

Transit's a solid choice for a conversion base. I've run similar setups in my motorhome and the key thing you'll want to sort early is your power architecture—don't leave it as an afterthought like some do.

South Wales weather means you'll want decent battery capacity since winter solar output can be patchy. Are you planning leisure batteries or going full lithium? Victron kit works brilliantly if you've got the budget, but Renogy gear's decent value if you're watching costs.

One thing @SussexSolar isn't wrong about though—water systems in a van are genuinely tricky in winter. You'll need proper insulation around pipes or you're chasing frozen systems come January.

What's your rough timeline and rough budget for the electrical side? That'll help point you toward what actually makes sense rather than what Instagram tells you to install. Also—where in South Wales? Might be worth knowing if you're looking for local installers or just sourcing parts.

Mate, Transit conversions are the gateway drug to off-grid living—one minute you're fitting a leisure battery, next thing you've remortgaged to fund a Victron setup and you're explaining MPPT charge controllers to your mates down the pub.

South Wales weather means you'll want serious roof space for solar panels, and don't skimp on ventilation or you'll be cultivating penicillin by autumn. The 2008 Transit's a solid chassis—parts are still cheap enough that you won't weep when something inevitably breaks.

What's your ballpark for total electrics? That'll massively influence whether you're looking at a simple Renogy job or going full Fogstar spec. Also worth knowing: narrowboat forums have some brilliant insights on battery management in damp UK conditions if you end up parked anywhere near water.

Post your solar plans once you've sketched them out—reckon you'll get some proper feedback here rather than the usual YouTube bro nonsense.

Right, welcome aboard @DodgyCaptain. Transit's a bulletproof choice—the 2008 vintage sits in that sweet spot where you've got reasonable payload and the engine's proven reliable without being overly complicated.

One thing I'd flag that hasn't been mentioned yet: get the chassis properly assessed before you sink money into the build. Rust underneath can absolutely torpedo a project, especially on Welsh vans that've seen salt air. Have a proper look at the floor pan and sills—Transit floors are notoriously vulnerable if they haven't been maintained.

On the electrics side, an 2008 Transit's alternator output is decent (around 130A depending on spec), which matters if you're planning EV charging infrastructure later—several of us here have experimented with solar + alternator top-up systems for vehicles. Not essential from the start, but worth designing your battery bank and leisure circuits with future expansion in mind.

What's your payload situation looking like? The 2008s vary quite a bit depending on whether you've got the LWB or short wheelbase, and that'll dictate how much battery capacity you can realistically carry without comprom

Cracking project, mate. South Wales is brilliant for solar too—decent winter irradiance compared to some parts. The 2008 Transit's got good bones for a conversion. What's your rough timeline and are you thinking full off-grid or just topping up the leisure battery on trips? Always keen to help if you get stuck with the electrics side.

South Wales is genuinely brilliant for this. I'm running solar on a shepherd's hut setup and the winter output surprised me—better than expected given the latitude. With a Transit you've got roof space to work with. What's your power budget looking like? That'll determine whether you go Victron or something more compact. The 2008 frame'll handle decent weight too if you're thinking batteries.
