Worth knowing that Victron's own documentation specifies the Multiplus II transfer time as <20ms, which sits comfortably within the tolerance of most sensitive...
@AGM_Geek the interconnect resistance issue bit me hard on my motorhome build — 280Ah Eve cells in a 48v configuration.
Had this exact issue last summer with my Multiplus 12/3000. The spin cycle creates a massive inrush current spike that the inverter sees as an overload, even if your steady-state draw is well...
Been through this exact planning phase myself before fitting my MultiPlus-II 48/5000/70 in the motorhome, and the wiring diagram stage is where most people make costly mistakes before a single...
Running into an interesting issue with my setup and wondering if anyone has experience with this.
Background: I'm currently spec'ing out a system for a fairly large property — not quite a country...
@VanGill @Davo24 — on my SPF5000ES I found this was nearly always the display ribbon cable losing contact, especially after temperature cycling over winter.
Been scratching my head over something on the motorhome setup this week. Running a Victron SmartSolar 100/30 with 400W of panels (two 200W Renogy mono in series), feeding into a 200Ah Fogstar...

Worth pulling the BMS data log if your Fogstar unit supports it — the 12V 200Ah does expose some diagnostics via the app.
@JimChapman74 Scotland is genuinely one of the better places in the UK to consider small wind — Pitlochry gets reasonable exposure and crucially your worst solar months (Nov–Feb) correlate almost...
@AndyWilliams makes solid points about static installs changing the game. One thing worth flagging specifically for Harris: the grid there runs through SSE and reliability can be patchy — storms...

@MarineGeoff worth checking your SmartShunt's Peukert exponent and charge efficiency factor in VictronConnect — both need adjusting for LiFePO4 (Peukert closer to 1.05,...

Worth flagging something nobody's touched on yet — your SmartSolar 100/30 will need reconfiguring if your panel array changes between the static and the van.

Worth adding that the Victron GX Touch 50 will only show what the Cerbo actually knows about — so your Growatt's AC output load figures will appear as a black hole in VRM...
Been planning the DC side of my motorhome build and keep going back and forth on this. Currently running a 200Ah Fogstar Drift LiFePO4 as my leisure bank, charged via 400W of roof solar through a...
@ValleyWanderer and @SmartSolar_Master are hitting on something crucial here. The psychological shift is real, but I'd frame it differently based on my own setup.
Living off-grid forces you into...
