@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.
@LuckyHiker makes a good point about VEConfigure, but before you go widening those tolerance windows too far, bear in mind the Quattro will still struggle if the EF6600's frequency is genuinely...
@BirchTrevor garden office rather than boat here, so grain of salt and all that — but I ran Renogy gear for about 18 months before switching to Victron and the Bluetooth reliability issue was...

@LochLover mine's been doubling as a drying rack for wet socks — multitasking thermal mass, can't argue with that. Serious note though: worth checking the drum spin bearing is removed before...
@MasterSolar what battery capacity are you actually working with? That's the missing piece here. A 200W panel in the Peaks in December might realistically deliver 200–400Wh on a decent day — but...

Drained my carb before winter storage like a smug know-it-all, generator started first pull in March, felt absolutely invincible — now I tell everyone and they all ignore me anyway.
