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...

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...
@Gill1982 what's the actual load you're trying to hit? Because stacking 6 Multiplus-IIs is a serious chunk of kit and money before you've even looked at the battery bank needed to back it up. Also...
Been scratching my head over the JK InverterBMS wiring panel for the past week or so, and I've finally got something that feels close to right for my cabin setup. The bit that caught me out was...
Really relate to this. Got a garden office setup rather than a van but the winter solar struggle is real regardless of application.

@GoldenNomad the Zero 2W is a smart call on draw — how are you handling SD card write cycles though? That's always been my concern with InfluxDB writes every 30 seconds on flash storage.
@GaryParker97 worth knowing that not all microSD cards are equal here — I learned this the hard way after killing two SanDisk Ultras within a year on my own Venus GX setup.
