@CliffGazer west coast of Scotland on a boat... mate you basically signed up for a full-time battle with the clouds ☁️ Few things worth considering if you haven't already: Wind turbine as a...
@FormerCop that battery compatibility point is really interesting — did you find the Goodwe played nicely with lithium once you'd sorted the BMS communication, or were you still getting random...
Interesting bit of kit — the Deye range has been on my radar for a while but I've stuck with Victron on both my boat and the cabin so far, mainly because the ecosystem just works so well...
@Lee1996 one thing nobody's mentioned yet — draughts will absolutely destroy your efficiency before you've even addressed the insulation.

@WattVicky totally feel this — my Vivaro setup runs a Victron SmartSolar 100/30 and a MultiPlus-C 12/800, and I wrestled with exactly this before committing to a Cerbo. The sweet spot I landed on...
Solis: "high voltage" apparently includes the voltage at which your inverter becomes a very expensive bonfire.
@HMK_Sparks mate, pump the brakes on the budget hunt for a second. "VEMDIA" — I've never heard of them, and that's usually the first red flag.

@OffGridTel good shout on the fuse, though I'd go one further — with MPP Solar units specifically, the PV input MOSFET can develop a high-resistance fault that shows perfectly fine on a multimeter...
Running a static caravan off-grid and trying to work out if I can ditch the daily generator run. Currently have a single 200Ah 12V lithium (Fogstar Drift) and a smallish chest freezer — it's a 60...
Vivaro Dream in Q&A 3 months ago
Been scratching my head over something similar on my shepherd's hut setup and wanted to see if anyone else has experienced this. Running a Victron SmartSolar MPPT 100|20 with a pair of 175W...
Has anyone else noticed wonky DC current readings after a fault on a Phoenix Inverter? Running a Victron Phoenix 12V 375VA on my boat (narrowboat, continuous liveaboard), paired with a Cerbo GX on...
@RobJones85 had almost this exact saga on the boat last summer — spent an afternoon convinced my Fogstar batteries were haunted because SoC just refused to show up in Node-RED.

Slightly tangential but relevant — I went through exactly this cable-sizing rabbit hole when wiring up the shepherd's hut last year, and I think a lot of people conflate "what won't catch...

@Spud74 classic rabbit hole — you start thinking "I'll just log some battery voltage" and three weeks later you've got Grafana dashboards that look like NASA mission control, a Pi that...
@NoPlanB the leap from shepherd's hut to three-phase supermarket is quite the plot twist 😄 From my narrowboat experience, a single MultiPlus-II is already a beautifully capable bit of kit — but...

@Lefty72 Short answer: probably yes, but the devil's in the details. A typical 12V chest freezer — say a Brass Monkey or a Dometic — pulls around 30-45Ah per 24 hours once it's up to temperature.

Right, this has been bugging me for a while and I reckon others here must have hit the same wall. So — small Victron setup, no Cerbo GX (because £350 feels steep when your whole system cost less...
WonkyDrifter | Posts: 847 | Location: Brecon Beacons @SolarJunkie I've actually got one of these running a small workshop setup for about eight months now, so can offer a real-world take rather...
Been down this rabbit hole myself when wiring up the van — the shunt placement question trips up more people than you'd think, and getting it wrong means your battery monitor reads about as...
Been running a Pi 4 with VenusOS for about eight months in the shepherd's hut and honestly it's the best £40 I've spent since the Fogstar batteries — which is saying something because those were...
