I've had my Cerbo GX running for about four months now and on the whole it's been brilliant for keeping an eye on the whole system from the VRM portal.

Mid-way through wiring up my off-grid shepherd's hut and trying to nail down the DC-DC charger setup.

@ValleyChild similar setup in my van but same battery — the Drift has been solid through the cold snaps we've had.

Cerbo_Geek | 1,204 posts | ⚡ Power User Worth flagging something nobody's mentioned yet: your MPPT 75/15 needs its battery profile updating.

JackieEdwards75 replied: @OllieThompson73 Worth considering the temperature coefficient on LiFePO4 as well — you genuinely do lose usable capacity in the cold, it's not just the BMS playing up.

Running a Drift on my narrowboat — similar boat to @BoatGemma I suspect. The low temp cutoff has triggered twice this winter when the cabin cooled overnight.

@MidlandsNomad great timing on this question — I went through exactly this decision last year. The Sterling B2B is brilliant kit but honestly the price premium is hard to justify for most van...

@ShortCircuit56 Worth doing the maths quickly — a 100Ah lithium at 12V gives you roughly 1.2kWh usable (assuming you're not hammering it below 20%).

WheresMeWires31 | 🔋 Member This is exactly why I started looking into emergency backup more seriously.

BoatGemma | 34 posts On my boat setup I found the charged voltage threshold was the sneaky culprit — the default setting assumes lead-acid voltage curves.

@DustyHiker I'll give you an honest answer from bitter experience — last January at my static caravan in the Midlands, my flat-mounted 200W pulled barely enough to keep my Fogstar 100Ah ticked...

Shoved a 200Ah Fogstar Drift under my hut's bench seat back in October and so far it's not exploded, which I'm calling a win.

Dead right on all the above. Something I'd add from running my shepherd's hut through two grim Novembers — don't underestimate the value of a smart schedule.

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...

MountainBarry | 287 posts | Array Done exactly this on my cabin setup for going on three years now. Mixed a 250W Renogy with two older 190W panels on a single SmartSolar 100/50 — all in parallel,...

@SaltySocket great project, those Drift cells are a solid foundation. One thing nobody's mentioned yet — think carefully about your BMS placement.

@Lee1968 has the inrush angle covered, but worth noting something specific to the 24V Multiplus 2 3000: at 24V your battery-side current during that inrush spike is enormous — we're talking...

@CamperRachel running a similar hybrid setup on my narrowboat — solar does the heavy lifting in summer but wind genuinely earns its keep Oct–March when the panels are struggling with low sun...

Good timing on this thread — just came through a similar stretch in Yorkshire. One thing nobody's mentioned yet: a small wind turbine as a complement to solar works brilliantly for exactly these...

Really useful thread this. One thing worth adding to what @CotswoldVanLifer and the others have covered – if you're seriously considering EV charging, it's worth looking at the MultiPlus-II GX...
