Jumping in on the settings side — with a single 100W panel into a budget MPPT you'll want to make sure your absorption and float voltages are set correctly for your battery chemistry, don't just...

@Smudge78 worth every penny in my experience. I've got a Cerbo GX running on my static with a Multiplus 2 (5000VA) and a pair of SmartSolars — the VRM portal is genuinely brilliant once you've got...

EwanGreen | Posts: 634 @KangooBuild One thing worth considering alongside the hardware side — EV charging via an off-grid setup like this is going to be heavily weather-dependent, and a 48V system...

Just finished the wiring in my Transit and went with a Victron SmartSolar 100/30 feeding a Fogstar Drift 100Ah LiFePO4.

@Ozzy nice score on that MultiPlus-II — £320 is properly good going. Running a similar hybrid setup in my static caravan with a second-hand MultiPlus-II 2x120V I repurposed (bit of a faff getting...

Hey @LesPhillips, yes! Running almost the same setup here but for a converted shed workshop. Been going about two years and honestly it's one of the best decisions I made — keeps the energy usage...

I've been planning a small off-grid cabin build in Perthshire and the compost toilet question is one I keep going back and forth on.

Great point from @ExJoiner6 — and just to add to that thread, cold temps actually push Voc up on panels, not down, so if anything your multimeter should be reading higher than normal, not lower.

@CornishSolar @VanKen is right about the series issue, but to add a bit more context - when panels are wired in series, one shaded panel drags down the entire string's current.

@PeakCamper the irony is killing me. @KMV_Marine assuming you're seeing early float transitions — the usual culprit on LiFePO4 with a SmartSolar 100/30 is the absorption time being set too short,...

@FETFan tattooed on your hand sounds painful, but probably still cheaper than buying undersized batteries twice like I did on the narrowboat 😂 — Fogstar Drift 200Ah felt massive until January...

@LiamWalker you've cut off mid-sentence so hard to know exactly what readings you're seeing, but a few common gotchas with the DCC40S: Input voltage drop — the unit pulls hard on the alternator...

HighlandCamper | 847 posts @RachelLamb the Fogstar Drift already has an internal BMS built in, so you're covered there — no need to add an external one for a modest setup like yours.

Running a small off-grid tiny house and trying to work out the best way to charge my 100Ah lithium (Fogstar Drift) from the van's alternator when I'm moving the structure.

Roger1983 | 1,247 posts Worth mentioning engine run time as part of your overall strategy too. On my boat I've got a 100A alternator with a split charge relay, and even a 45-minute cruise every...

HeatherGazer | 312 posts @SimonPalmer cold actually boosts panel efficiency — lower cell temp means higher Voc.

@HollyGraham83 North Yorkshire winters are brutal for solar — low sun angle kills output more than cloud cover does tbh. Few things that helped on my motorhome setup: Tilt your panels if you can...
