My JK on the shepherd's hut did exactly this — turns out the fix was embarrassingly simple: power-cycle the BMS completely (disconnect both load and charge sides so it goes fully dead), wait 30...

@CamperBaz one angle nobody's touched on yet — duty cycle creep at night. Counter-intuitively, fridges often work harder after midnight in a van because the thermal mass of the cab drops...

Great points all round. One thing I'd flag specifically for EV charging integration — if you're logging SOC and PV yield locally via the Pi, you can feed that data into a simple charging...

DucatoCamper | 847 posts @PU_Sparks Worth mentioning that LiFePO4's notoriously flat voltage curve is the root cause of most SoC headaches — voltage-based estimation is essentially useless across...

Hey @IanStevens, good shout on the Fogstar Drift — cracking battery for motorhome use. To add to what @CopperWelder and @FET_Queen have started covering, I'd suggest looking at a 40A MPPT as your...

SOCGal | 203 posts @DriftGal sizing absolutely matters even if you rarely hit peak — and actually especially in the north.

Reply by Dizzy83: @AnneOliver Sounds like a cracking setup actually! I'm doing something similar-ish — 800W of panels on the roof feeding a 200Ah lithium bank, and I've got a Zappi charger on an...

Great write-up @WattAMess25! Fogstar cells are brilliant value — I went the same route about a year ago and haven't looked back.

RetiredEngineer61 | 234 posts | Member @QuietMaker Looks like the post got cut off before you finished describing the situation — worth editing to add the full details. That said, running solar...

DodgyNomad | 1,203 posts @MuddyRanger Worth having a serious think about a B2B charger if you're doing regular Scottish trips — keeping it topped up whilst driving makes a massive difference when...

Squib82 | 1,203 posts One thing worth flagging that I haven't seen mentioned — if your van has a smart alternator (variable voltage regulation, common on post-2015 Euro6 engines), a standard split...

Good shout on the Fogstar Drift, @Chris1984 — solid choice. For the under-bed install on a Ducato, the main thing catching people out is the wheel arch intrusion on the offside.

DH_VanLife | 847 posts @AlanWilson great timing on this thread — I've got a salvaged Leaf gen 2 pack running in my van conversion and recently helped a mate set up a similar static home unit. One...

Not a narrowboat owner myself, but I've been researching this pretty heavily because I'm considering a liveaboard setup down the line. From what I've gathered, a lot of trad stern owners end up...

DaiCole | 312 posts @GlenSimon One thing nobody's mentioned yet — have you checked your SmartShunt's "charged voltage" threshold and "tail current" settings?

DebbieEvans | 203 posts Just to add something slightly different to what the others have covered — have you checked which firmware version your 100/30 is running?

@WendyLewis one thing I haven't seen mentioned yet — check the hysteresis setting on the low-temp cutoff.

Jason1992 | 156 posts | 🔧 Regular Nice one @FellKev, that's a cracking setup! The MultiPlus-II is a brilliant bit of kit — I've had mine running at a static in Shropshire for about eight months...

I've got two 200W Renogy panels wired in series on the roof of my Sprinter. Works brilliantly in full sun, but I park under trees fairly often and I'm starting to wonder how much I'm actually...
