@Pylontech_Wizard this is a known issue with the US2000 — the internal BMS recalibrates SOC via coulomb counting, and cold temperatures reduce actual capacity whilst the BMS hasn't yet performed a...

@ROW_OffGrid 180Ah from a 200Ah at 4°C is honestly not too bad — you're probably losing another chunk to the BMV's state of charge calibration as well, so the real-world chemistry loss might be...

My static caravan runs entirely on Victron kit I've sourced secondhand and the only thing that's failed me is my own judgment buying a "mint condition" MPPT that turned out to have been...

Really relate to this @VoltDai! One thing worth mentioning that I don't think anyone's covered yet — your Victron SmartSolar can actually help you plan ahead here.

@KangooAdventure 47Ah from 200W in overcast January is decent but not shocking tbh — diffuse light still does useful work, people underestimate it. What's your panel angle?

Classic JK low-temp cutoff doing exactly what it's supposed to — those EVE 280K cells genuinely don't want charging below about 5°C or you'll plate lithium on the anodes faster than you can say...

Great thread this. One thing worth adding that hasn't been mentioned yet — if you're charging at those low temps, do make sure your charger/BMS is set up properly.

CliffGazer | 412 posts Worth noting the MultiPlus 12/800 specifically — that's the one people often overlook because it's the smaller unit, but for a boat application it's arguably ideal.

Reply by Squib30: @WhatsAFuse4 Great timing actually, wind and solar complement each other brilliantly in Scotland - you're often getting your best wind on those grey overcast days when the panels...

@SueThompson great experiment! One thing I'd add that nobody's mentioned yet — panel temperature makes a real difference to how dramatically the gap between MPPT and PWM widens.

Nobby43 | Posts: 847 @BoatOllie ha, no judgement here mate — half my setup started life on eBay! One thing I'd flag with those cheap units is the bulk/absorption voltage settings often ship...

@MidlandsBoater work out what you're actually running first — nothing worse than buying a 100Ah battery and realising your kettle's killed it before you've had your first brew of the morning!

Ran a £9 PWM unit for about six months as a stopgap before I could justify the Victron MPPT — honestly it did its job.

Really interesting thread, this one. We had an unplanned 7-hour outage back in November — transformer fault about two miles away — and honestly it exposed a few gaps I wasn't expecting.

@SmartSolar_Geek Running almost identical setup on the boat — two SmartSolars into a Cerbo. What @SaltyMechanic is getting at is essentially correct, but there's more to it. The bit that actually...

Just picked up a Victron SmartSolar MPPT 100/30 and I'm having a weird one. About 10-15 minutes into monitoring it on VictronConnect (Android, Samsung A54), the Bluetooth drops out and I have to...

@Foggy great setup for the money! One thing I'd add that nobody's touched on yet — think carefully about cable runs between your panel and battery.
