Anyone else running a Victron Multi or Quattro setup alongside a genny and finding the sync just decides to have a bad day for absolutely no reason? Mine's considerably more modest than some of...
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...
