@QuietMaker cable runs are the silent killer of shepherd's hut builds — everyone obsesses over the panels and battery, then realises halfway through that their 4mm² twin-core won't cut it over a...
Ran into this exact thing on my van build last year — drove me absolutely mental for weeks. Spent ages convinced the Fogstar cells were playing up before I finally twigged it was the re-sweep all...

Really interested in this thread because I'm mid-spec on a 48V upgrade for my motorhome emergency backup setup and the golf cart format looked attractive space-wise. Quick question for anyone...

@BreezyDrifter the comms issue is almost certainly the VE.Bus configuration rather than the batteries themselves.
Anyone else gone down the rabbit hole of trying to marry a Victron Multiplus-II GX with SolarEdge kit and LG Chem batteries, or is it just me torturing myself on a Sunday afternoon? Running a...

@FormerMariner24 @CotswoldVanLifer raises a valid point on cabling, but I'd also look specifically at your Multiplus's Low Battery Voltage and Dynamic Cut-Off settings in VE.Configure.
@TQ_Builds interesting one — I went through something similar when I wired up my static caravan setup, though I was using the older Lynx BMS rather than the NG variant. Few things worth checking...

Been puzzling over this one for a while and could do with some guidance from those who've already sorted it. My setup is a static caravan with a Victron MultiPlus-II as the inverter/charger,...

Good point from @Compo — and I'll add the ambient temperature angle, since it's a narrowboat. In summer, if that battery's sitting in a warm engine bay or sun-baked stern, your usable capacity...

Got a static caravan rather than a shepherd's hut but the heat retention problem is basically identical — small metal/thin-walled structure that bleeds warmth the moment the fire dies down. What...

@NaeClue13 Worth noting that the Shelly Mini EM Gen4 uses the newer Shelly Gen4 API which isn't yet natively supported in VenusOS 3.80~33 — the existing Shelly EM integration in Venus was built...
Classic inrush current problem, and honestly 500VA is cutting it very fine for any motor load. Motors typically draw 6–8x their rated running current at startup — so your 220W (roughly 1A running...
So this one's close to home for me — literally happened in my van last winter parked up on the South Downs during a proper storm.
@MoorHamish sounds like the post got cut off mid-sentence — what are you actually seeing? Error codes, weird charging behaviour, panels not producing expected output? A few things worth checking...
Been down this exact rabbit hole with mine — took about three weekends longer than I expected, but the end result was absolutely worth it. The thing that caught me out was underestimating the...

Good shout from @ExFirefighter on the smart alternator point — that's caught a lot of people out. Just to add to that thread: if you're running a solar-to-starter battery setup on a Fiat Ducato...
Hey @PennineSolar, I've actually got one of these running in my shed setup since about March. Honestly for the money it's been decent enough - no complaints on capacity, it's hitting close to the...

Right, so this is something that's been gnawing at me for a while now, particularly as I'm leaving the narrowboat unattended for increasingly longer stretches over winter. We all know the drill...

@Jock has touched on the standing charge issue but there's a more granular point worth making here: the shape of consumption matters enormously.

Those are some seriously tempting prices, though I'd be cautious jumping straight in with an unknown brand like ECGSOLAX at that wattage.
