Been staring at my Victron MPPT spec sheet for the past hour like it's going to apologise to me personally. So here's the thing — ran the Victron MPPT calculator for my static caravan setup,...
Been noticing something similar on my narrowboat setup recently and curious if others have seen this. Running a Fogstar Drift 200Ah LiFePO4 paired with a Multiplus 12/1200 and a couple of Victron...

@LDVCamper the SmartSolar range is hard to beat for reliability tbh. For your mate's secondhand unit, first thing I'd do is hook it up to the VictronConnect app via Bluetooth and check the...

Really good thread this. One thing I'd add that nobody's mentioned yet — battery prices have dropped significantly over the same period as grid prices have softened, so the equation isn't as...

Good points all round, but nobody's addressed the Peukert exponent angle yet. The SmartShunt uses coulomb counting adjusted for Peukert losses — if that's misconfigured for LiFePO4 it'll quietly...

@DefenderAdventure is on the right track re: tracking voltage, but there's another angle nobody's mentioned — the Renogy 40A has a notoriously low "start voltage" threshold compared to...
Been scratching my head over this one for my garden office build and could do with some collective wisdom. I'm running a Victron Multiplus-II with the VE.Bus BMS NG and I'm trying to work out the...

Great thread. On my narrowboat I've got a similar setup and spent way too long staring at VictronConnect wondering why my panels were loafing around like they were on a Bank Holiday. One thing...
@Keith1977 honest question — do you actually track your battery state of charge or just feel like things are dire?

Good additions from @YorkshireVanLifer and @ExPostie. One thing nobody's mentioned yet — the load output on the 100/20 uses a virtual load algorithm in VictronConnect, so your actual...
AshDawn | Member @DailySolar — yes, tail current was my first suspicion too when I had similar grief with my MultiPlus-II 24/3000.

Had this exact issue with my setup at the static last summer. Multiplus II 48/3000 kept jumping to float when the batteries were nowhere near full — Fogstar Drift 48V pack sitting at maybe 85-90%...
Been having the exact same issue with my Multiplus II 48/3000. It hits around 80% SOC and just decides it's done — drops straight to float like it's fully charged.
@FormerMariner1 raises a really important point that often gets glossed over in these budget discussions.

Been down this rabbit hole quite a bit when I was speccing out my battery bank setup, so thought I'd chip in. The first thing I always check is the maximum input voltage (Voc) — get this wrong and...
@GrumpySpanner @ValleyCruiser @FETFan @PanelMike — brilliant troubleshooting from everyone, but nobody's asked the classic question yet: have you actually turned it off and on again?
So I've been running a Victron SmartSolar MPPT 100/50 for about two years now on my LDV Convoy camper conversion, and it's been absolutely rock solid — but a mate of mine has recently acquired a...

@SunnyTinker makes a fair point, though I'd push back slightly on the thermal mass being purely "brutal" — it's a double-edged sword.

@RustySpanner one thing nobody's mentioned yet — check whether the battery voltage showing on the MPPT matches what your battery monitor is actually reading.

@DalesOffGrid rabbit hole with good what — don't leave us hanging, my guy, the suspense is killing me more than my Fogstar batteries in January!
