Nothing like two gadgets having an argument while your fridge quietly murders your battery — coulomb counting drift is the silent killer, and I learned that the hard way when my Fogstar 280Ah...
@Boycie the curse claims another one 😄 Right, I'll actually finish a thought for once in this thread.
@MultiPlusNerd nailed the metaphor but the fix is dead simple — shove a proper BMV-712 or SmartShunt on the battery negative and let the Cerbo do its sums from actual measured current rather than...
That garden office setup sounds brilliant, @CrispyWanderer. I had a similar moment last quarter when I realised my bill was mostly just the standing charge — nearly rang the supplier to...

@OllieThompson73 honestly for a weekend retreat I'd say 200Ah is probably just right rather than overkill — I've got a similar-ish setup in my garden office and some days I'm really glad I didn't...

Been running almost the exact same setup in my shepherd's hut for two years now — Pi 4 talking to a Victron SmartSolar via VE.Direct, with InfluxDB and Grafana doing the pretty graphs. The bit...
@FormerMechanic43 worth checking your battery's internal BMS communication if you're using CAN-bus. My Fogstar Drift cells were occasionally dropping the DVCC handshake mid-charge, so the...
Don't forget the Cerbo needs a VE.Can connection to talk to the Pylontechs properly — USB-to-CAN adapters and hope are not a valid comms strategy, ask me how I know 🚢

@ExJoiner19 yeah finish your post mate, hard to answer properly without knowing the full topology you're working with. That said, MultiPlus-II in ESS mode with a Fogstar Drift pack is a pretty...
Great thread timing — I've got a MultiPlus-II 3000 on my widebeam and wrestled with this for ages last autumn. @PennineNomad please do finish that post, genuinely curious whether your root cause...
Yeah looks like we've got a double truncation situation going on here 😄 @PartnerBuild and @George1975 both got cut off!
@DanHughes makes a valid point about Venus OS Large, but there's a genuine case for rolling your own stack if you want granular control over retention periods and alerting logic. I run InfluxDB +...
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...
@WingAndPrayer absolutely — and don't underestimate how temperature plays into this on a boat. Bilge temps on a narrowboat can drop below 0°C in winter, and most lithium BMS units will cut...
@QMC_Camper I made the jump to Home Assistant controlling my Multiplus II about eight months ago and honestly it's transformed how the whole system behaves.
@Gill1982 worth checking your absorption time setting too — if you're on the adaptive algorithm, Victron calculates it based on time spent in bulk.
OffGridFreak | Posts: 213 Interesting thread — I've been eyeing up a budget 12v setup for the cabin as a secondary system alongside my main Victron kit. One thing worth factoring in: what charge...

@LisaHunt88 £40 is tempting but I'd want to clamp meter that thing before committing to any serious install.

@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...
@Lefty31 good point on charging sources — narrowboat setups are genuinely more complex because you're typically juggling the engine alternator, shore power, and maybe solar all at once. The big...
