Selling: Complete van solar kit — emigrating!

Victron 3kVA system with 10kWh lithium — bargain for quick sale

Right, bit of a shame to let this go but we're off to Portugal next month and need to shift it. Everything's barely 18 months old and in excellent condition.

What's included:

• Victron MultiPlus 3000/24 inverter/charger
• 10x 100Ah LiFePO₄ (BYD or similar, honestly can't recall exactly which batch)
• 6kW PV array on aluminium rails (east-facing, solid output)
• Victron MPPT 250/100 charge controller
• Battery management system with Bluetooth monitoring
• Full cabling, breakers, DC/AC distribution

System's been running a 1.5-bed tiny house — powers everything including heating pump and workshop tools without drama. Monitoring via Victron Connect app has been faultless.

The ask: £6,500 for the lot. I know it'd retail at nearly double that, but I need space cleared and I'd rather it went to someone actually building off-grid rather than sitting in a warehouse. Happy to negotiate slightly if someone collects the full thing this month.

Collection: Based near Ashford, Kent. It's heavy gear so realistically collection makes sense, but if someone's genuinely committed I could discuss part-posting the controllers and monitoring kit separately. Van's already packed so sooner the better.

Not splitting — want it gone as one job. Works perfectly, no faults. Can provide photos and full system documentation if interested.

Any questions just ask.

That's a decent spec for a van. How's the lithium been for you in practice — any issues with the BMS or charging cycles?

What's the actual asking price? Might be worth posting that in the title next time, saves people asking. Also curious whether you're selling as a job lot only or open to splitting? Know a few folks after batteries specifically right now.

Whereabouts are you based? Postage on a Victron unit that size won't be cheap, might be worth mentioning local collection options if possible.

@Fiona1974 raises a good question there. I'm running a similar Victron setup in my shepherds hut and the lithium's been rock solid so far — no BMS hiccups or balance issues. That said, Brian, couple of things worth asking:

What's the actual depth of discharge you've been cycling to? And have you got data on charge times with whatever solar array you're shifting with it? The real test for lithium is whether you're genuinely cycling it daily or if it's been sat mostly full.

Also worth knowing — is that 10kWh usable or nominal? Makes a difference for what folks can actually rely on.

Only asking because I'm considering bumping my own bank up and these details matter more than the specs sheet suggests. Where in Portugal are you headed, out of interest?

Been running Victron gear in my cabin for three years now and it's solid kit. The lithium packs are bulletproof if you've kept them properly maintained — what's the charge history like on yours @BrianBrown?

Only thing I'd flag: make sure whoever buys this knows about the BMS settings. Mine needed a bit of tweaking early on to play nicely with the inverter, nothing major but worth mentioning in the listing. What's the warranty situation transferring over to a new owner?

Price seems fair for the spec tbh. Van conversions are proper competitive right now though so you might need to shift it quick if you're genuinely keen to move before Portugal.

I'd be keen to know the exact lithium chemistry and cell manufacturer — LiFePO4 specs vary quite a bit. What's the BMS firmware version on the Victron stack? There was a known issue with older revisions around thermal management in vans where ambient temps can swing wildly.

Also worth asking: what's your actual usable capacity after accounting for the battery management settings? I've seen people spec 10kWh nominal but only get 8-9kWh usable because of conservative cutoff thresholds. Not a deal-breaker, just something @Fiona1974 should factor in if she's planning EV charging top-ups alongside regular loads.

The van environment is harsh on batteries — constant vibration, temperature swings, humidity. Have you done anything beyond the standard Victron setup to protect against that? Insulation, thermal blankets, that sort of thing?

Price point matters too depending on answers to the above. Van-ready lithium systems are pricey new, but secondhand longevity depends heavily on how it was actually used versus how it was spec'd on paper.

Mate, if that lithium's been behaving itself for 18 months you've basically won the lottery. Most of us spend half our time refreshing the Victron app at 2am convinced something's about to explode.

@VitoProject's asking the right questions though — BMS spec genuinely matters. I've seen some cheap knock-offs that treat

Have you got the specs on the battery management system and what the charge/discharge limits are set to? That's usually where the real difference is between the bargain packs and the ones that'll still be working in five years.

The Victron side of things is obviously bulletproof—@LesCrane's right about that—but I'd want to know if this has been through a proper winter or just fair-weather use. That changes things considerably. Also worth checking: have you run it through any extended off-grid periods, or has it mostly been top-up charging?

Given you're emigrating, I'd be upfront about the usage pattern in your listing if you haven't already. Buyers will pay more knowing whether it's seen real workload or just weekend use. And @VitoProject's asking the right questions—if it's dodgy cell chemistry, that'll cost someone a grand to replace in 18 months' time.

What's your asking price looking like? Might help gauge whether you're pricing for quick shift or hoping to recoup most of the outlay.

Decent kit there by the looks of it. Before you shift it though — how's the Victron system been configured? I'm curious whether you've got the battery low-voltage disconnect set conservatively or if you've been running it harder. I ask because I'm looking at a similar setup for a van conversion project and want to understand real-world wear patterns.

Also worth knowing: have you any documentation on cycle counts from the BMS? That'll actually matter more to a potential buyer than the calendar age. Ten grand's worth of lithium can degrade quite differently depending on whether it's been sitting at 80% or regularly cycled deep.

What's your asking price anyway? Might be worth checking what the Victron Multiplus II is selling for new these days — that'll set your baseline. If you've got the original commissioning sheets from installation that'd be a solid selling point too.

The real question is whether you've got the system dialled in properly before offloading it. A 3kVA Victron with 10kWh lithium is solid kit, but configuration is everything and most folk don't realise how much of the performance depends on how it's been set up.

What I'd want to know is: have you actually logged into the GX device and checked your battery history? The charge/discharge curves, cell balancing, any BMS faults logged? If you've been running this without tweaking the lithium profile settings in the Victron software, you might have capacity you don't even know about.

Also worth documenting — have you run it through a full cycle recently? Not just "went off-grid for a week" but actually discharged to genuinely low states and charged back up. That'll tell you real usable capacity versus what's on the nameplate.

Potential buyer's going to want that data. Proves the battery's healthy and you haven't been running it with dodgy BMS settings that'll cause them grief down the line. Screenshot your system history from the app before the sale — it's worth more

Fair play getting shot of it before the move. That 3kVA is solid for a garden office setup like mine — been running Victron stuff for years, rock solid. Main thing: make sure you've got all the original commissioning docs and BMS settings documented. Saves the new owner a headache trying to figure out what's been tweaked. Glws with the sale.
