Currently running a 200W Renogy panel through a Victron SmartSolar MPPT 100/20 on my Transit-based motorhome.

Just finished wiring up my van build and I'm pretty happy with the Cerbo GX as a central hub, but I'm running into a few blind spots.
Good point from @T5Solar on cable routing. In my shepherd's hut setup I don't deal with alternators but I did have similar thermal throttling grief with a Victron Orion in the motorhome last...

@Will1961 had the exact same issue with mine on the garden office build — JK 200A active balancer, same EVE cells funnily enough. Turned out to be a power supply problem to the BMS communication...

@VivaroNomad ran a Renogy 200Ah in my last van conversion for 18 months before switching to Fogstar Drift cells — the Renogy's fine until it isn't, whereas the Drift just quietly gets on with it...

DevonCruiser | 847 posts @Curly — worth checking what transfer switch setting you're running in VE.Config.

DownsCamper | Posts: 2,341 @Hamish1980 Worth adding to what's already been said — your MPPT is calculating SoC primarily from voltage, and the problem in winter is that a cold AGM sitting at 12.6V...

Hey @CornishSolar — worth checking whether you've got the battery temperature sensor set up properly in VictronConnect.

Good shout from @EcoFlow_Queen on checking actual voltage under load. One thing I'd add — have you looked at where your B2B charger itself is mounted?

DebbieKelly | 📍 Shropshire | Posts: 312 @Curly7 That combination will easily pull 2500W+ so you're pushing that unit pretty hard.

Finally got round to expanding my static caravan setup and ended up with a bit of a Frankenstein array.
@BayTim is right on the nominal voltage there. @CrispyMender good shout on the SmartShunt, that'll serve you well.

@HarryMorgan the detail that actually matters here, which nobody's mentioned yet: those two 200Ah batteries you've ordered — are they internally 12V cells or 24V cells?

Great thread @VoltDai! One thing I'd add that nobody's touched on yet — have a look at your battery's state of charge before those short winter days even begin.

Thinking about upgrading my current 200Ah AGM bank on the narrowboat to LiFePO4. The Fogstar Drift 200Ah cells keep catching my eye, mainly on price, but I'm trying to work out if the real-world...

@BatterySam nice setup — the 100/20 should handle that 175W panel comfortably, you've got headroom too if you ever want to add a second panel later. Quick question though — are you running the...

@MeganFox interesting setup — what battery capacity are you running with that? I've been debating doing something similar for a shepherd's hut I'm converting into a home office/occasional cabin.
Solar Doug in General Chat 3 months ago thumb_up 2
Yeah, this catches a lot of people out. The root cause is that LiFePO4 cells have a remarkably flat voltage curve at normal temps, but cold shifts that curve downward — so the controller's...

@Chris1991 worth checking your actual Voc in cold conditions — a 200W mono panel can easily push 24-25V open circuit when it's properly cold, and your 75/15 handles that fine.
