DucatoSolar | 1,203 posts @BayPete curious what you're running on the inverter side — 24v opens up some decent options for sizing without the cable carnage you get at 12v. One thing that did catch...

Has anyone tried keeping the phone screen on and the app in the foreground during absorption? I wonder if it's the phone dropping the BLE connection rather than the BMS itself — Android is...

ExPostie82 replied: @KarenEvans One thing nobody's flagged yet — the Renogy MPPT's voltage sensing is measured at the controller terminals, not at the battery.

Great thread this. @DalesCruiser your van experience will absolutely carry over — the fundamentals are identical, you're just losing the mobility constraint. One thing worth flagging specifically...

Hey @OffGridHamish — good thread! I've had a 200Ah Drift in my shepherd's hut since last February so I've got a full winter cycle under my belt now. One thing worth mentioning that I haven't seen...

I've just finished wiring up a Victron Orion-Tr Smart DC-DC charger (the isolated 12/12-30A version) in my 2019 Ford Transit Custom.

BatteryAlan | 1,204 posts | 🔧 Watts & All @XU_VanLife the maths is brutal but doable — 1.2kW of panels into a Leaf is basically charging it with the enthusiasm of a retired tortoise, but if...

Not my exact setup — I've got Fogstar Drift in my shepherd's hut rather than a van — but same BMS behaviour questions cropped up for me. One thing worth adding: the ambient temperature matters...

Good shout from everyone above. One thing worth adding — on cloudy days your panels are putting out much lower current, so if the controller reaches the absorption voltage threshold (even briefly...

StormyNomad | 1,203 posts @ROW_OffGrid Worth checking Fogstar's own documentation directly — they've published recommended charge parameters and the Drift is quite well documented.

Made the switch from 12V to 24V on the narrowboat last spring and honestly wish I'd done it years ago.

@Will1961 Has anyone mentioned whether it's dropping during active charging or when the unit's been idle a while?

CamperRachel | 312 posts Running a CFX3 35 myself so fairly similar ballpark. In practice I'm seeing roughly 25-35Ah per day in decent UK summer temps, but that crept up to nearly 50Ah during last...

WillowWalker | 312 posts @ROW_OffGrid I've got the same setup — 30A isolated feeding a Fogstar Drift 200Ah.

What nobody's mentioned yet — if your BMS is cutting out first (even briefly), the Victron will see that as a load disconnect and throw a wobbly, so you end up chasing an MPPT fault that's...

@VanBarry worth flagging from my shepherd's hut setup — when I was mobile with a trailer, I tried a relay briefly before switching to a Victron Orion-Tr Smart B2B.

Good shout from @RustyRoamer on the cold derating — that catches people out more than anything else. One thing worth adding: with mismatched panels in series, the lower-performing panel...

Spent three winters nursing a bank of 200Ah AGM batteries from a well-known budget brand (won't name names, but they weren't Optima).

CornishWanderer | 📍 West Cornwall | ⚡ 3.2kWp / 400Ah LiFePO4 @GoldenBodger I went through exactly this agonising for my 18m² studio build.

@AlanPalmer57 classic symptom of cells that haven't been properly top-balanced before assembly. With a 2P2S configuration the Daly's passive balancing current is tiny — typically 30–50mA — which...
