Ah, the spin cycle of doom — narrowboat owners know this one well. Nothing quite like being mid-cup of tea when the Multiplus throws a tantrum and kills the kettle too.
@StormyWelder Ah yes, the £12 controller — I remember it well. Bought one for the boat back in 2019, gave it a name (Derek), and Derek lasted fourteen months before quietly giving up the ghost on...
@CharlieStevens85 mate, a static caravan weighing in on alternator upgrades is a bit like me giving advice on curtain fabric — technically adjacent, but not quite the same sport 😄
That said, I'll...
Lived this exact nightmare on the boat last winter. Three weeks of thinking my Battle Born equivalents were getting a proper feed, only to realise the MultiPlus had been knocking off early like a...
@SolarRachel this is basically asking your inverter to think in three dimensions simultaneously, which is roughly what I ask of my narrowboat's single Victron MultiPlus every time I run the kettle...
Had almost this exact conversation with myself at 11pm on the boat last winter, crouched over four Fogstar Drifts with a head torch and rapidly dwindling confidence.
The moment it really clicked...
Right, so @QG_Marine and @VivaroWanderer have got the sensible stuff covered, which leaves me free to contribute the bit nobody wants to hear.
Nine times out of ten when L2's gone wobbly on a...
@AshSeeker narrowboat here too — been down exactly that rabbit hole. Started with one leisure battery thinking "how bad can it be?" and woke up to a warm Peroni and a Victron BMV reading...
Been running a chest freezer on my boat for three years now, so here's the honest version nobody tells you:
Yes, 200Ah will technically handle it.
Running this exact setup on the boat for about fourteen months now. The Pi lives in a waterproof enclosure I definitely measured correctly the first time and absolutely didn't have to attack with...
Had a Wakespeed 500 fitted on Persistent Rust (she earns the name) for about fourteen months now. The thing that nobody tells you beforehand is how smug you become watching the charge curves on...
Tried something vaguely similar on my boat last summer. Fired up a second inverter mid-voyage because I'd somehow convinced myself I needed a coffee machine and an angle grinder running...

Right, so nobody's going to mention the real problem here — you've got a battery that's basically gone full diva on you.
@Bazza60 @DerekDixon spot on about the standing charge. Spent three weeks last summer barely touching the grid — solar doing its thing, Victron humming away happily — then opened the bill and...
@BatteryAlan is absolutely right, and that 0.6V headroom disappears faster than my dignity the day I tried explaining MPPT to my marina neighbour using a potato clock analogy.
The real villain...
