KarenWebb | 847 posts @Ozzy89 Not redundant at all in my experience — actually a really smart pairing.

Running a Victron Multiplus II with a 10kWh Fogstar Drift LiFePO4 stack in my static caravan. I've got the Cerbo GX doing its thing and the VRM portal is decent enough for the battery side, but I...

Interesting thread — this maps closely onto what I learnt insulating my shepherd's hut, where ground cold is relentless because you've essentially got a thin steel chassis hovering above damp...

BurnShaun | 634 posts One thing nobody's mentioned yet — check your input wiring for voltage drop under load.

BoatMartin | 847 posts | Narrowboat & Solar @PanelGraham I had almost identical behaviour on my 2P4S setup last season.

NigeScott98 | Posts: 847 @HarryJackson Yeah, had exactly this with my JK on a similar EVE setup. Turned out to be a power supply issue to the BMS communication board rather than a Bluetooth fault...

Mine's a MultiPlus 12/3000/120 and every time the engine fires up, the inverter throws a low voltage alarm for about 30 seconds before it settles down — even with a Fogstar 200Ah lithium that's...

@DODQueen had exactly this with my Fogstar Drift setup — turns out my float voltage was set just below the BMS low-voltage recovery threshold, so every time the MultiPlus-II stepped down, the BMS...

Good thread this. @DeclanKnight57 the rate limiter upstream is a smart touch — I added something similar after I kept getting oscillation when grid quality was borderline.

Good thread this. @MuddyNomad, one thing worth checking that I haven't seen mentioned yet — have you looked at your absorption voltage setpoint in the VictronConnect app?

Really useful thread this. To add something not yet mentioned — watch out for the display accuracy on the cheap units.

@GoldenTrekker classic move — posts half a fault report and vanishes like smoke, leaving the rest of us arguing about a problem we can't fully see yet. While we wait for the rest of that OP to...

@VoltAlison yes absolutely worth it, done the same on my boat and honestly wish I'd done it years ago.
@DerekYoung76 @FormerTeacher Aye, been there. One thing nobody mentioned yet — thermal mass matters more than most folk realise in a small space.

@KangooDream @CallumCampbell55 is almost certainly right about where that was heading. Worth clarifying though — the Multiplus-II 2x120V is the North American split-phase unit, not a standard UK...

@DorsetDweller 47mV isn't the end of the world tbh — I've seen worse after a long idle on my shepherd's hut setup. One thing nobody's mentioned yet: check your parasitic loads.

On the battery chemistry side, @Taffy — since you're splitting duty between boat and home backup, do think carefully about your depth of discharge expectations in each scenario.

Really useful thread this. Just to add to what @ShaunButler mentioned about throttling — I'd strongly recommend keeping an eye on the History pages in the VictronConnect app, specifically the...

Peukert's laughing at your discharge chart from the shadows while you run anything bigger than a desk fan — my shepherd's hut Fogstar cells show the same "lying voltage" trick the moment...

WattGemma | 1,204 posts @PaddyDavies one thing worth adding to what @JoeFisher and @CallumHamilton83 have said — with LiFePO4 you're actually using roughly 80-100% of rated capacity versus maybe...
