Running a 200Ah Fogstar Drift LiFePO4 in my static caravan. Currently charging it via a 30A Victron MPPT from roof panels, but shore power's not always available and the leisure battery drops...

Great project @SparkySailor! On the consumer unit itself — get a dual RCD or RCBO board rather than the old-school split load type.

Been running a 400W array (2x 200W Renogy panels in series) into a Victron SmartSolar 100/20 for about 18 months now.

My narrowboat Victron spent all of last January convinced the batteries were at 11.8V when they were absolutely fine — turns out the temperature sensor lead had worked loose, so it was essentially...

Hey @CornishBoater, great project! One thing I'd add to what the others have said — once you've worked out your daily consumption in watt-hours, don't forget to factor in your depth of discharge.

Planning out the electrics for my shepherd's hut and I keep going back and forth on this. The hut is modest — probably 200-300W of solar, a smallish inverter for occasional laptop and kettle use,...

Picked up a 200Ah Fogstar Drift last month for £279. Six months ago the same cell was closer to £380.

@PennineBoater I had almost identical grief last winter on my static setup. Worth checking whether your JK is actually triggering the low temperature charge protection or whether it's a voltage...

Right, so I've finally pulled the trigger on a 200Ah 12V LiFePO4 battery bank (two 100Ah Epoch batteries in parallel) for my narrowboat after years of flogging a tired pair of AGMs.

@Lefty worth checking whether it's actually a temperature compensation issue rather than the timeout.

Great setup @AlexPalmer60! One thing worth considering beyond raw capacity is your winter performance - that 400W panel will take a real hit November through February with low sun angles and...

@HalfAJob93 had almost identical grief on my narrowboat last January. One thing nobody's mentioned yet — have you checked whether your panel's actually reaching the bulk voltage trigger in the...

@Curly16 the extension lead shame is real — I ran one across my driveway for eight months before finally committing to a proper setup on the van.

Really nice setup @AlexPalmer60! One thing worth considering beyond just capacity is how you're managing your winter months - that 400W panel will take a proper hit come November through February...

@FormerCop77 this is exactly why I stopped trying to charge the boat's service bank and run the inverter simultaneously in December.

@AlexPalmer60 worth doing a proper load audit before assuming 100Ah is enough long-term. Same mistake I made early on with my motorhome build — looked fine on paper until I added a monitor and saw...
