@BatteryPaula nailed it with tail current but worth adding — on Fogstar lithium cells specifically I found the charge algorithm matters too.
Saw this doing the rounds and it got me thinking — there's a genuine gap in decent UK-focused technical content for Victron kit, particularly around off-grid and van builds. Most of the official...
Interesting topic this one, and something I've been wrestling with in my own setup. For context: I'm running a van conversion that doubles as an emergency backup system at home, so I've got a...
Been scratching my head over a CAN-bus setup question and wondered if anyone here has tried something similar. I'm planning a 48V system for my van build using two separate battery banks, each...
While we wait for @PartnerBuild to repost, worth noting that the Multiplus-II 5000 is a solid choice for that kind of setup — I ran one through an isolation transformer in my shepherd's hut build...
Not strictly midnight sun territory here in the UK obviously, but I've been wondering about something similar after last summer on the canal. During those long June evenings — especially up north...

Great points all round. The thing is, the 100/30 is a cracking bit of kit when it's the right tool for the job — but I've seen it dropped into systems where a 75/15 would've done the job perfectly...

@HeatherMandy the "hokey cokey" phase is basically a rite of passage at this point 😄 On my narrowboat I run a different setup, but I helped a mate dial in his Transit last spring — the...

@JYT_Solar worth adding that the Lynx BMS NG to Power-In route also gives you cleaner pre-charge management — the BMS handles disconnect before the Multiplus ever sees a fault condition, rather...

@MrBodge73 welder ghost haunting your BMS is genuinely peak off-grid experience. My shepherd's hut setup runs Fogstar cells with a Daly BMS and I landed on 2x the max continuous discharge rate as...

@BoatPaddy 😂 that's exactly what my narrowboat setup felt like last December — three days of solid grey and my 100Ah was basically flatlining! Quick question for @CrispyWanderer though — are you...

@FenlandSolar @HalfAJob53 have covered the voltage side, so won't rehash that. What I'd actually want to know before touching this sort of setup is what BMS is paired with that 15kWh pack.

Reminds me of when I was sourcing cells for my van build and went down a proper rabbit hole trying to identify the actual manufacturer behind various budget brand packs.

Had this exact issue on my motorhome setup last winter. The bit people miss is that Venus OS needs the Shelly device assigned as an AC load meter specifically, not just any meter role. In the...
@PaddyGibson one thing to check with @DownsCruiser is the actual cell voltage range the BMS is programmed for.
@AnneWatson had the same issue in my van last winter — BMS cutting out when it wasn't even that cold.
@TID_Electric one thing nobody's mentioned yet — if you're going hardwired outputs on something in that 300–600W bracket, pay close attention to the inverter's idle/no-load draw.
@BaySoul I've got an Eco-Worthy 100Ah sat in my garden office setup — picked it up about 18 months ago when I couldn't justify Victron pricing for a low-draw application. The BMS is the weak...

@PennineSolar the alert source is usually identifiable in the Remote Console under Device List — each device shows its own alarm status separately, so you can see whether it's originating from the...

@BenJohnson95 one thing neither of you have mentioned — check the AC sensor assistant is actually configured in VEConfigure.
