Blimey, this hits close to home — had a similar headache with a Victron MultiPlus in my van build where the sparky who fitted it bought it through some dodgy grey-market channel and the paper...

TrevorEvans replied: @HazelDawn Classic narrowboat winter dilemma! The short answer is — trust neither blindly, but lean toward the SmartShunt if it's been properly calibrated. The BMS SOC is...

Similar situation to what a few people have raised elsewhere — running off a limited grid supply and wanting to boost capacity without accidentally pushing power back. In my case it's a static...
Been running a rewound induction motor on my narrowboat for about 18 months now — the key thing nobody mentions alongside the rewinding faff is the rectifier setup afterwards.

Great summary from @Liam1990 on CVL/CCL. One thing worth adding — if you're seeing the charge voltage drop lower than expected even when the BMS isn't actively throttling, double-check your DVCC...

SussexBoater | 203 posts | ⛵ Floating Off-Gridder @GemmaCooper86 The Victron MK3-USB interface and a copy of VE.Flash have resurrected more "bricks" than I care to admit — on the boat...
Been thinking about this a lot recently after reading about someone stateside running a similar-style build on a converted coach — twin Multiplus II 5kVAs feeding a 240V split-phase panel, which...

@NicolaTaylor72 that boat test is genuinely useful data, cheers for doing the legwork. My two penneth: I ran a no-name PWM on my van conversion for about eight months before the magic smoke...

@RayPowell just to add to what @DucatoLife is getting at — the 100/30 has a max input voltage of 100V, so you'll want to check your panel's Voc on the datasheet and then apply a temperature...

Seen this crop up a few times and had something similar with my own Multi-II 48/3000. Worth methodically working through the likely culprits before assuming it's a hardware fault. Most common...

@DevonNomad the Devon November test is genuinely underrated as a metric — I'd add the "parked in a Scottish layby for a fortnight" variant for van conversions specifically. What I'd...

@QIH_Electric speaking from bitter experience here — ambient temperature is the variable everyone ignores until it bites them. I ran a Lec CF100 on my narrowboat through a February freeze and...

Had this exact issue on my narrowboat last summer — Orion 30A would drop out after about 45 minutes of cruising, then recover after 10-15 minutes.
Had this exact head-scratcher on my narrowboat last winter. Both my Fogstar 200Ah LiFePO4 BMS and the Victron SmartShunt were confidently telling me completely different things — one said 74%, the...

Great thread, this. @SomersetVanLifer I'd also look at your tail current setting in VictronConnect if you haven't already — it's the one that often gets overlooked.
Bit of a strange one to admit, but yes — happened to me in the first year after setting up my static caravan system. The thing nobody tells you is that going off-grid doesn't automatically make...

@Bazza60 @PanelSteve worth noting that the standing charge situation has actually worsened for low-consumption grid-tied users over the past few years as suppliers have shifted more network cost...

@Moorey44 raises a valid point — spec sheets are optimistic. I've got a Victron SmartShunt on my narrowboat and the actual cycling behaviour varies quite a bit depending on ambient temperature and...

Had a similar headache in my van build — running a Victron Orion-TR Smart 24/12-70 to step down from my 24V Fogstar Drift lithium bank to feed the 12V leisure circuits, and noticed the output was...
Just discovered something odd with my MultiPlus 3000 120 on the boat and wondering if anyone's seen this before. Been running shore power at the marina for the past few days and noticed the...
