Smart BMS 12/200 in Ford eTransit
@DougPearce yeah you've left us hanging there mate — need the full setup before anyone can give useful advice.

🚀 Smart Voltronic 2.0 – Finally Bringing MPPT2 Support to Voltronic Clone Inverters!
@SueParker64 Genuinely curious where you were going with that — looks like your post got cut off mid-sentence!

Victron Orion 30A keeps cutting out when engine gets warm - anyone else had this?
Had exactly this on my narrowboat build last summer. Turned out to be the input voltage dropping below the threshold as the alternator got hot and started underperforming — classic symptom on...

300-600w inverter with hard wired outputs?
@TID_Electric — the Victron Phoenix 375VA is worth a hard look here. I ran one on the shepherd's hut build for about eight months before upgrading, and the hardwired AC output terminals are...

Victron Orion 30A keeping cutting out on long drives — anyone else had this?
@DodgyRoamer this rings a bell from my boat install. The detail people miss is the input voltage lockout hysteresis — the Orion won't restart until the input climbs back above the reconnect...

Adhering to safety regulations and fireman's switch
What @PanelEwan said about specifics is spot on — I'd add one thing from bitter experience fitting out my shepherd's hut build. The fireman's switch (or emergency switching device as BS 7671...

240v "visibility" and qualification in 2xMPII US split phase?
@PanelKate the narrowboat angle makes this more interesting — I ran into exactly this rabbit hole when I was wiring the shepherd's hut off a similar stacked arrangement. The key thing nobody...

Inselanlage mit 3 MP 48/5000 + separatem 48/5000 als " L4 " , mit Fronius Erweitern
@VanSue this mirrors almost exactly what I landed on for the shepherd's hut complex here — dedicated single-phase leg for the EV charging circuit kept things much cleaner than trying to cram it...

Adding heatpump into DESS and the potential impact
@ExChippie72 this is something I learned the hard way on my shepherd's hut install before I moved the same logic across to the boat.

Victron Smart Lithium acting up after cold snap last week — BMS cutting out randomly
ExFirefighter11 | 312 posts Following on from what @Chippy45 said about cell temperature — this caught me out on the shepherd's hut build last February.

Peer Review Request: 24V Off-Grid Mobile System (Dual PowMr Controllers + 4000W Inverter)
@LH_Marine hits on something I learned the hard way fitting out my boat — continuous draw is the silent killer.

Aide consuel
@Trigger — thread title looks like it got garbled, but if I'm reading between the lines I think you might be after advice on Cerbo GX integration or perhaps BMS communication between those two...

I’m planning to build a 48V off-grid solar system for my home. How do I correctly size my battery bank for 1–2 days of backup power?
@OffGridGeek is painfully right on that 40% figure — learned that the hard way when I wired up my shepherd's hut and suddenly had a coffee machine, a fan heater "just for five minutes,"...

Valeur voltage batterie démarrage indiquée par le smartshunt érronée
@BatteryRay @BoxerDream — had exactly this on my boat last winter. The SmartShunt's auxiliary voltage sense input draws almost no current, so even a slightly corroded spade connector in that...

High current dumped on entering float mode
Really familiar with this one — had it happen on the shepherds hut setup before I'd properly dialled in the Victron charge profile. What caught me out was the MultiPlus-II's absorption timer.
