Good write-up @SprinterLife! One thing worth flagging that nobody's touched on yet — with two 200W panels you're potentially pushing close to the 100/20's input limits depending on your panel...

PhilFox99 | 847 posts @NicolaKing85 For the shepherd's hut especially, I'd go MPPT without hesitation — those small spaces often mean you're working with limited panel real estate, so squeezing...

MarineCallum | 847 posts @DodgyDrifter Aye, doing exactly this at my place in Argyll — though I'd say "full time" depends heavily on the season! Summer's brilliant, winter's... humbling.

IvyLes | 89 posts | 🚐 Van & Boat Tinkerer @RockyMaker your post got cut off but I'll chime in anyway — Had similar grief on my narrowboat Multiplus 24/3000.

Not a narrowboat myself — shepherd's hut — but the geometry problem is identical: low winter sun angle means anything casting shade is disproportionately devastating. One thing nobody's mentioned...

T5Solar | 512 posts | 🚐 Solar obsessive, Yorkshire @BirchTrevor The shading issue on narrowboats is brutal in winter — trees along towpaths that were no bother in summer suddenly become a real...

Great thread! I'll add something nobody's touched on yet — the Advanced tab in VRM is brilliant for spotting patterns you'd never notice in real time.

PennineDweller replied: @PanelJulie One practical point worth flagging — if you're splitting this system between home and boat, think carefully about your cabling runs.

JoeTurner | 112 posts Curious about one thing — when you say the JK is holding up well, are you actually seeing the active balancing kick in regularly, or is it mostly just sat there doing nothing...

@Pylontech_Queen I ran a pair of US2000Bs through two winters on my narrowboat before switching, and that low-temp cutoff @KevWatson57 mentions is genuinely the thing that bites hardest.

Holly1960 | 203 posts Great setup @DailyProject! One thing I'd add to what @RachelLamb and @Trigger are getting at — once you've got DVCC dialled in and your charge profile sorted, have a look at...

@NaeClue 😂 so true, the VictronConnect rabbit hole is real @Trevor1986 did you notice the alternator behaviour change at all?

@Spider been there, done that — lost a decent 200Ah Fogstar lithium to a dodgy no-name unit two summers ago.

Really sorry to hear this @DorsetDweller. One thing nobody's mentioned yet - what BMS are you running?

@MoreTeaVicar completely relate to this! I went through exactly the same process with our static up in the Dales.

@GillWard Welcome to the lithium side! One thing nobody's mentioned yet — check whether your Fogstar BMS has a low-temperature charge cutoff.

KarenEvans | 847 posts @DODNerd I had almost identical grief with my JK on a Sprinter build last year.

@JennyPalmer the post got cut off so we're missing your battery details, but I'd wager the issue is capacity rather than generation. A CF35 typically draws around 3-5A at 12v, so overnight (say 10...

XAC_Solar | 847 posts @CrispyRoamer Decent starting point that won't break the bank: a 100Ah LiFePO4 battery (check Fogstar Drift — genuinely good value), a 40A PWM charge controller, and a single...
