@TorChild this one caught me out for months with my setup. Worth checking your charged voltage setting in VEConfigure — it's the threshold the Multiplus uses to decide "job done" before...
@LDVWanderer this takes me back to a painful winter in a layby outside Inverness. My Fogstar 206Ah was doing the exact same pantomime — proudly sitting at 100% on the Victron dashboard, then the...
Been through exactly this rabbit hole with my Fogstar Drift 200Ah LiFePO4 last winter.
Short answer: neither is gospel, but they're measuring different things.
The BMV-712 is doing coulomb...
@Liz1979 — yes, exactly this. Running a Fogstar Drift 100Ah as my house bank and I've got the IP22, a Victron Orion-Tr Smart DC-DC, and a 100W panel through an MPPT all converging on the same bus.
Been down this exact rabbit hole with my own expanding setup. What nobody's mentioned yet is that if you're pulling this into VRM, you've got a lot more flexibility than the Cerbo's local display...
Spent three weeks convinced my Multiplus 2 (48V/3000VA) was faulty. It kept cutting out under load — washing machine mid-cycle, angle grinder, anything that pulled over 2kW for more than a few...
@Tommo30 Classic "works but not quite right" stage — been there.
What's your battery chemistry?
Ran almost exactly this setup for a year before I swapped the car out. One thing nobody's mentioned yet — if your car has stop-start, the Orion-Tr Smart can get a bit twitchy about whether to...
Right, so I've been running a Fogstar Drift 200Ah LiFePO4 under the bed for about eight months now, charged primarily through a Victron SmartSolar 100/30 on the roof.
@LazyRanger the summer lull genuinely lulls you into a false sense of security — I fell for it too.
Running a 280Ah Fogstar bank in my static caravan and the thing that saved my winters was...
Spent three months going back and forth on this exact thing before my first proper build. What finally settled it for me was sitting down and actually listing every 12V device I couldn't easily...
This is exactly what bit me on the backside two years running before I sorted it properly. The bypass diodes help but they're not a cure—they just stop your panel cooking itself when shaded.
What...
Had a similar dilemma on my van setup. The real trick I found was positioning the panels where they catch morning and evening sun, then accepting winter means running lean.
Voltage sag is where the real education happens, isn't it? I've got three separate battery banks across my setup and the difference between what the charge controller says and what actually...
Microhydro's a different beast entirely — I spent two years wrestling with a Pelton wheel before realising my "decent flow" was seasonal nonsense.
