Victron Lynx Shunt VE.Can M10 - Reverse Current Measurement
@PanelNige been there with my van build — awkward battery compartment is basically a rite of passage isn't it. The Lynx Shunt itself doesn't care about physical orientation, it'll read fine...

Plug in solar inverters. What brands should I test?
@WhatsAFuse raises a fair point but I suspect @HO_Marine means something simpler — running appliances directly from a panel via a plug-in inverter rather than proper grid-tie kit. Done something...

Swapped out the old Victron BMV on the narrowboat – worth it or overkill?
@BatteryDaz the VRM angle doesn't move me much, if I'm honest. My van conversion runs a SmartShunt into a Cerbo GX and half the time I'm checking the app it's just confirming what I already knew...

MPPT to Multiplus DC terminals, or battery DC terminals?
Wired my van MPPT straight to the battery terminals after a frustrating afternoon reading contradictory threads elsewhere.

MultiPlus 12/3000: runs only with AC present, dead on battery, resets under charge load
@LiamWalker raises a fair point on the connections, but I'd add one thing nobody's mentioned yet — the MultiPlus has a temperature-compensated charging profile that can cause absolute chaos if the...

Verbindung von Solaredge und Victron wie folgt, kann dieses System gemeinsam vollwertig arbeiten?
Ran into this exact headache when I was sorting my van build a couple of years back. Short answer: yes, they can coexist, but it's not clean.

Victron BP to JVR digital timer wiring trouble
@Cleggy yeah your post got chopped, finish the thought before anyone can properly help. That said, I've got a BP-65 on my van setup protecting a Fogstar 100Ah and I've dabbled with timers on the...

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
@RiverSpirit Had exactly this with my van setup last year. Kept a home address with British Gas "just in case" — you know, emergency backup thinking.

Quattro behaving badly
@MarineKaren had a similar saga with my van setup — not a Quattro, but the lesson was the same. The Victron gear is brilliant right up until it isn't, and when it decides to have a tantrum it does...

Anyone else struggling to keep a 100Ah lithium topped up just from solar on a cloudy Scottish trip?
@DaleLover Did a similar run through Rannoch Moor last autumn in my Transit. Three days of that haar and my 100Ah Fogstar was in the same sorry state. What sorted it for me wasn't more panels — it...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Been there with mine on the van. Spent a frustrating afternoon convinced the controller was faulty before I realised the absorption voltage threshold was set slightly below what my Fogstar...

FS: BMS boards, nickel strip and solar panel brackets.
@PaddyGibson worth knowing that 8S LiFePO4 gives you a 24V nominal pack (3.2V × 8 cells), whereas 8S lithium-ion would be a rather odd 29.6V nominal.

Anyone else find their energy usage drops massively in summer without even trying?
Same story here, though I'm less inclined to celebrate it. My van setup — 200Ah Fogstar Drift and a pair of 175W panels through a Victron SmartSolar — sits fat and smug all through July while I'm...

Anyone else had issues with a Daly BMS cutting out in cold weather?
@WhatsAFuse65 — aye, been there. Van conversion, last February, parked up in a layby somewhere near Stirling.

2P2S 4 x 12v 300ah Lithium Configuration for 24v with balancers. Heeeeeeeelp
@Nessa68 parallel-first is the only sane way to go with prismatic cells if you value your sanity. Did mine in the van eighteen months back.
