@AndyGraham interesting setup — my experience is mostly motorhome-based but the winter energy maths translates directly. The killer issue in a static installation like yours is that you can't...

@WFS_Camper mine did this constantly in the van until I realised the BT module was just loose in the housing — a tiny wiggle and it'd drop out faster than my will to read another Victron manual.

WillWilliams | 847 posts | ⭐⭐⭐ @LuckyHiker sounds like you got cut off there mate — your post ends at "giving ~4"!

@DriftGal the 2am thing is real but honestly the dangerous phase for me was when I set up custom alarms on VRM.
Paul1987 | 847 posts Worth adding to what @PennineCruiser is getting at — the Orion-Tr Smart actually protects your alternator properly, which a basic split-charge relay simply doesn't do.

OddJobBob17 | Posts: 1,203 | Location: Shropshire @Lefty91 Worth adding to what @PartnerCamper said about the temp sensor — AGMs in cold conditions can show a surface charge fairly quickly, which...

@GlenChild this happened to me on a crossing to Brittany a few winters back — 2°C in the engine bay where I'd mounted my cells, BMS cut discharge at what felt like the worst possible moment. Worth...

@Chris1991 here's the thing nobody tells you about winter solar — your panel's voltage actually rises in the cold, which is great, but irradiance is so much lower that your wattage craters...

Great thread — @T5Project's point about Voc spikes is really important and something people don't always think about before wiring up. One thing I haven't seen mentioned yet: have you checked your...

Great thread — this is almost exactly my setup on the boat. I'm running a 200Ah Drift paired with a SmartSolar 100/20 and after a fair bit of experimenting I've settled on 14.2V absorption, 13.5V...

Finally took the plunge last month and replaced the ageing Varta AGM in my Ducato-based van with a Fogstar Drift 100Ah LiFePO4.
I've got a bit of a head-scratcher going on with my setup and wondered if anyone's been in a similar boat.

@DazHughes yeah had something similar with my SmartSolar last winter at the cabin. Turned out the battery temp sensor was reading way off because the sensor itself had come slightly loose from the...

Nobby43 | 156 posts @PanelMike good shout from @BreezyMechanic about winter - that's where most people get caught out.

VoltWendy | 847 posts My shepherds hut build taught me something the spec sheets don't tell you — cable runs are the silent killer of a 24v system.

JoeFisher replied: @BoxerDream one thing nobody's mentioned yet — check your repeated absorption time setting in VEConfigure.

So I've finally got my roof setup sorted on the Transit, or at least I thought I had. Running two 200W panels wired in series (so nominally 24V system), hooked up to a Victron SmartSolar MPPT...

Good point from @Pylontech_Wizard there — worth actually checking your cold morning Voc with a multimeter before assuming the MPPT is misbehaving.

Been running a 400W panel setup on my static narrowboat (two 200W mono panels, Victron MPPT 100/30, 200Ah AGM bank) and I've barely seen more than 40-50W coming through on most days this week.

Jim1980 replied: @BoxerDream worth having a look at your absorption voltage and absorption time settings in VEConfig.
