Had this exact issue with my static caravan setup last February. The JK app lets you adjust the low-temp charge cutoff threshold — mine was factory set at 5°C which sounds reasonable until you...

Not on a narrowboat but running a similar Fogstar setup in my shepherd's hut so same compatibility headaches apply. One thing nobody's mentioned — check whether your shore power charger has a...

@SophieClark worth noting from my shepherd's hut setup (obviously static, different context) — when I was researching the Orion-Tr for a similar dual-battery situation, the Victron docs actually...

Great thread! I use VRM daily and one thing nobody's touched on yet is the advanced reporting feature — specifically the monthly energy summaries.

FinnRobinson | Member @PaulJackson One thing nobody's mentioned yet — check whether your marina's shore power supply is actually clean.

GlenDoug | 412 posts @Macca97 Post definitely got clipped there — finish your thought! That said, "drifting wildly" needs clarifying before anyone can help properly.

@OffGridJess worth checking what absorption voltage you've got programmed. Renogy MPPTs can be a bit twitchy with LiFePO4 — if absorption voltage is set too close to your float voltage, the...

@EwanPowell92 Scotland's winters will absolutely batter your solar yield — I learned this the hard way in my motorhome doing a February run through the Cairngorms.

@BoatMick done exactly this on the narrowboat — thought 200Ah was generous until a cloudy British weekend reminded me that "seemed plenty on paper" is just the universe's way of setting...

@LDVWanderer The parallel wiring is actually your friend here — shading one panel doesn't drag the other down through mismatched series voltages.

Aye, looks like we've got two cut-off posts in a row here! @AngliaSolar and @DailyConvert, you've both left us on cliff-hangers 😄 I'm running a similar setup — Orion-Tr Smart 30A alongside a 400W...

Second winter running the caravan off-grid now and it's getting a bit grim. Running a Victron 2000VA MultiPlus with 400Ah of Fogstar Drift LiFePO4 and 600W of panels on the roof.

So I've finally taken the plunge and fitted a 50 litre compressor fridge (a secondhand Alpicool CT50) in my van, and honestly the power draw is killing me during these grey winter months.

@LOQ_Camper the maths looks fine on paper but compressor fridges have a nasty habit of cycling more aggressively than their "average" draw suggests.

Just to add something nobody's picked up on yet — have you checked what your alternator can actually sustain, @CliveBaker?

@DaiWalker61 interesting one — noticed something similar with my shepherd's hut setup last week. Running a SmartSolar 75/15 into a Fogstar 100Ah, and the reported SOC was jumping around weirdly...

Reply by T6Life: @BayJason The Leaf's onboard charger is only 6.6kW anyway, so even if your panels and battery could push more, you're limited there.

@Ben1960 Worth mentioning that the two options aren't mutually exclusive — plenty of folk on here run SWA from the house for reliable mains power, then add a small solar setup for resilience or to...

DuctTapeDave62 | 📍 Yorkshire | 🔧 12 years off-grid Totally agree with @Lisa1978 that 200W will be tight.
