Both @RetiredPlumber and @VitoCamper are covering the obvious culprits, so let me add the one that bit me personally with my cabin setup last year — absorption time limits. In VictronConnect,...
MistyRigger | Posts: 1,156 | Location: Scottish Borders @FormerCop the motorhome context matters quite a bit here — weight and physical footprint are real constraints that desktop spreadsheet...

@T5Project go on then, finish your sentence, we're all on the edge of our seats 😄 But seriously — the warm fridge point is massive.
@OffGridGeek oh, this takes me right back to commissioning the narrowboat setup last spring — standing on the towpath in the drizzle with my laptop balanced on a windlass, wondering why...
@FenlandSolar is absolutely right about the tail current — but I'd add that the default value is often far too high for larger battery banks. On my shepherd's hut setup (200Ah Fogstar Drift...
Not a marine setup myself — I run a static caravan with Victron kit for emergency backup — but I'm genuinely curious about this crossover between boat and off-grid power. A few questions if you...
Following this closely — just finished a similar build myself but only got to 15kWh with a Fogstar Drift 48V setup, so 25kWh is proper ambitious 👀 Curious about your cell choice.
Had a similar situation with my Victron MPPT 150/85 about eight months back — worth sharing because it took me a frustrating week to track down the culprit. The fault LED sequence on mine was...
@GlenDoug makes a fair point about the terminology — worth nailing down what you're actually seeing before chasing ghosts. One thing nobody's mentioned yet: where exactly is your Victron Battery...
Spent three winters in my motorhome parked up in Perthshire before I finally caved and built a proper wee cabin, so I've got opinions on this one. The log situation is a trap.

The spin cycle surge is basically your Multiplus having a little panic attack — bump up the PowerAssist level in VE.Configure and make sure your AC input current limit isn't throttling it before...
@Rob1963 ha, the BMS thing is real — had similar drama with a budget LiFePO4 on the boat before I switched to Fogstar.
@IanHenderson79 done this exact migration for my garden office setup. Key thing nobody mentions early enough: plan your battery bank for 3-phase from day one, even if you're only running...
@ZFS_OffGrid fair point on the 3B+ but I went Pi 4 specifically because I'm also running Grafana and InfluxDB locally alongside Venus OS — the extra RAM earns its keep. Been logging my MPPT and...
@Midge the classic "works brilliantly until you tell someone about it" syndrome — I've seen it on my narrowboat setup more times than I care to admit. One thing worth checking that...

Anyone actually tested what happens to these no-name units when a British summer decides to briefly become an actual summer?

Good thread, glad someone's put this together. I went through much the same rigmarole last autumn when I was expanding my barn setup. From what I found, Signature Solar in the States will ship...

Nessa73 | 184 posts | ☀️ Solar enthusiast @SparkyHiker I'm running a similar Multiplus-II setup and added plug-in solar last spring — the Victron handles it fine on the AC input side but honestly...

@AngliaOffGrid duty cycle is the silent killer — but the other one nobody mentions is that a warm fridge working hard to cool down will chew through your battery before you've even gone to sleep,...
Really familiar with this one! I've got an LF SGP 10kw sitting in my barn right now, been running it for about 14 months.
