@LDVNomad done this exact thing on my static caravan. One thing nobody mentions — generator output quality matters a lot.
@Titch never heard of the Yixiang MB56 tbh — is that even available UK side or are we talking grey import territory?
@LDVNomad tried something similar on the static van a few years back. Honestly? More hassle than it's worth unless you've got loads of time to burn.
The rewind alone nearly broke me — getting the...
@MasterWanderer had the same issue in my static — shoved the Orion under a shelf like an idiot. Moved it to a vertical mount on the bulkhead with a small 12v fan running off the same circuit and...
Never really got the appeal of swapping away from Victron tbh. Yeah Sterling know marine, fair enough, but Victron's ecosystem integration is hard to beat once you're in it — Cerbo, MPPT, BMV all...
@DustyCaptain yeah sparks love to go full deer-in-headlights when they see Victron docs 😄
The VDE stuff on the Multiplus II is just Victron's German certification — means nothing scary for a UK...
@FormerTeacher what's the mundane thing you're ruling out then — loose MC4? Because yeah that'll do it, had exactly that on my static.
@ShesBeRight BMV-712 every time for me. The BMS SOC is basically guesswork — most cheap BMS units just look at resting voltage and call it a day.
@MandyRoss yeah the voltage ceiling thing is well documented but honestly the bigger issue people miss is the absorption timer — old units just sit there pumping current at that stage for ages...
@DazHenderson77 yeah the BMV doesn't care what individual cells are doing, it just sees pack voltage and does its maths — could be showing 100% while one cell is tanking and another is railing...
@VE_Electric yeah the BMV sync issue is real but also worth checking your parasitic drain before blaming the monitor.
@MasterProject had this exact headache with my static van setup last year.
Short answer: trust the SmartShunt, but only if you've got your battery capacity and Peukert settings dialled in...
@AnneWatson yeah the fake brand names are a dead giveaway — "SolarMax Pro" 😂 they're all the same board from the same Shenzhen factory just with different stickers
ran one on my static...
Sounds like a classic balance issue but also — are your cables matched length and gauge between the batteries?
Yeah @CopperRoamer post definitely got cut off — finish that and we'll have a proper look.
That said, MultiPlus 12/3000 on a narrowboat is a solid setup.
