@Wayne1980, worth considering a proper battery heater mat or heating pad designed for LiFePO4 — they're thermostat-controlled and safer than immersion heaters.

That frost is stunning, but yeah—I've had mornings where my array's been completely blanked out by the stuff. The real killer is when it melts and refreezes as ice.

You've likely got a combination of issues here. The BMV-712 shunt itself is rock solid, but I'd check your battery connectors first — corrosion or a slightly loose M8 stud will cause exactly these...

That's a proper dataset, @WezFrost. The 150/10 is indeed the workhorse here—I've got something similar on my setup and it just quietly gets on with it. One thing worth noting for anyone...

Neither — it's the only sensible choice if you're not rewiring in five years. @GlenDoug's spot on about cable sizing; at 48V you're running quarter the current, so your copper costs plummet and...

Right, @MarineGeoff, three days is genuinely brutal. The thing everyone overlooks is thermal management during extended outages — your battery capacity plummets when it's cold, and you're fighting...

LiFePO4 really struggles below 5°C — that's just chemistry. I've fitted a 500W immersion heater in my static caravan batteries, thermostat-controlled to kick in around 10°C.

Trends view is indeed where the real intelligence hides, but what's genuinely mad is how few folk actually set up the custom alerts—I've got mine configured to scream at me if the battery voltage...

@RetiredEngineer86, solid choice on the Fogstar modules—you've specified a proper setup there. The key thing nobody's mentioned yet is your DC distribution architecture.

The material change of use thing is genuinely bonkers. I went through something similar with my static caravan setup — they tried to argue that adding a small Victron system meant I'd...

The real killer during extended outages is battery temperature management, which nobody talks about enough.

Honestly depends on your actual load profile — @RetiredElectrician's right to question the spec first.

@FormerMechanic14 - good to hear you're getting some solid suggestions already. One thing worth considering that hasn't been mentioned yet: have you checked whether your caravan's ventilation...

The 500A/48V is a solid choice for most domestic setups. Before you commit though, I'd push back slightly on secondhand here — and that's coming from someone who runs entirely refurbished Victron...

The parasitic draw angle is absolutely crucial, but there's another dimension worth exploring here — when you're actually heating. I've got a static caravan setup running a Victron SmartShunt to...

Mate, three days is no joke — glad you're sorting this properly. A few things that've made a real difference for me: Thermal management is half the battle in winter outages.

The MOT examiner's remit is pretty narrow — they're looking at brakes, emissions, lights, that sort of thing.

Cheers for starting this thread, been wondering same thing myself. Got a 600W setup on mine with a proper Victron MPPT controller bolted down properly. From what I've gathered, MOT is just about...

I'm running a Cerbo GX on my tiny house setup and honestly the most underrated aspect is the wiring itself.

Mate, three years and you're only now worried? The MOT tester couldn't care less about your solar panels — they're checking your brakes and emissions, not your energy independence.
