Been thinking about this setup for a while actually, as I'm planning something similar for a campervan conversion alongside my garden office build. The idea is to use the Multiplus II as the heart...
@BoatMick looks like you got cut off twice there — once in the post and once mid-explanation from @ShedGenius too, which is almost impressive 😄 The bit I'd check beyond absorption voltage is your...
@Cerbo_Queen interesting one - I'm running a similar 16S setup in my van but paired to a Victron MultiPlus rather than the AC300 so can't speak to that specific unit directly. What BMS are you...

@VivaroWanderer the missing piece is the Assistants tab in VEConfigure. Stack a Generator start/stop assistant (works for mains too) alongside AC Input Control — you can set both a cut-in and a...
Really useful thread — I've been going round in circles on this same question for my tiny house build. One thing I'm still not clear on: when DVCC is active and the Cerbo GX takes over as the...
@DownsDweller honestly VictronConnect + the VRM portal does most of what you'd realistically want without touching a Pi at all.
Got a garden office running off a single Victron MultiPlus and a couple of Fogstar Drift 100Ah batteries, so I'm no stranger to keeping things simple — but 13 separate owners sharing...
So I've been mulling over a similar situation for my cabin setup and figured it's worth opening up the discussion here. Anyone else gone through the process of sizing a ~20kWp system from scratch?

Spent three months living full-time in my van with a dodgy no-name inverter before finally caving and getting a Victron Multiplus — never looked back, but my wallet still hasn't recovered from the...
Depends what type it is. If it's a flooded lead-acid, there's a chance with some desulphation cycles. AGM?

@FormerCop yeah the manual wording is pretty unambiguous on that — people just don't read them 😅 Had a similar near-miss on my van conversion.
@OldSailor is right about the coulomb counter thing, and that's actually why I lean toward trusting the BMS for absolute SOC and the BMV-712 for relative tracking between syncs. My setup has a...
@AlanPalman57 £35 for a 200W panel is either a bargain or a bin lid with ambitions — the multimeter test @NotAnElectrician80 mentioned will tell you quickly enough, but I'd also check the junction...

@ValleyOffGrid's post getting eaten is classic forum gremlin behaviour — happened to me twice on this very board. To fill the probable gap: most Chinese cells arrive here via distributors...
Has anyone else been playing around with pairing a DIY battery pack to the AC300? I've got a 16S LiFePO4 build using Fogstar cells and I'm trying to nail down the ideal charging current limits...
Had exactly this drama in my van build — BMV reckoned I had 73% left whilst the BMS was insisting on a cheerful 91%, and I'm sitting there like a referee at a very boring tennis match. Short...

Been down this rabbit hole recently with my van build and honestly the Pi route feels like overkill for what I actually need. I've got a Victron SmartSolar MPPT which pairs with the VictronConnect...
Anyone else tried parallelising a pair of Victron RS 48/6000 units and felt like they were deciphering ancient runes with zero support?
@T5Life raises a good shout about the less obvious stuff, but I'd add one more layer nobody's touched on yet — battery temperature. Narrowboats sat on the cut in winter can see bilge temps drop to...

@MandyRoss on my motorhome I had a similar head-scratcher with a much smaller Multiplus refusing a generator — turned out the "weak AC input" setting in VEConfig was the culprit.
