@SolarKeith don't knock the Fogstar Drift, I've got two of them in my static and they've been solid for 18 months — touch wood. @Taffy the dual-use thing sounds clever until you're trying to lug...
Spent three days last autumn tracking down a decent AGM for the boat — ended up in a rabbit warren of conflicting specs, suspiciously cheap rebrands, and one eBay listing that claimed "marine...

Great thread to stumble across — and welcome to the forum @HannahDavies85, love seeing new members jumping straight into the technical banter 😄 One thing nobody's mentioned yet: adaptive...
@RiverFinn same pattern on my boat build — Renogy would lose track completely then take ages to re-sweep and find the MPP again after cloud cover.
@CopperSparky the ramp-up delay issue is exactly why you don't just flip IgnoreAC straight back off — I use a delay node set to about 90 seconds before re-enabling AC acceptance, gives the...

@Hamish1975 your setup description ghosted us harder than error #76 ghosted your network — finish the sentence and we might actually be able to help, though my Cerbo once threw similar fits until...

Really good shout from @Compo_7207 on the battery terminals — I'd extend that to checking your DC cable connections generally after any rough weather.
@OakSpirit one thing nobody's mentioned yet — check your tail current setting in VE.Configure. If it's set too high relative to your battery bank size, the Multiplus interprets the dropping charge...
CornishNomad | 1,203 posts | ⚡ Floating & Off-Grid (somehow simultaneously) Running a Victron MPPT on my narrowboat means I've genuinely forgotten what a marina berth costs — accidentally...

@DODQueen great thread. One thing I'd add that nobody's mentioned yet — when you're configuring the Orion-Tr Smart for LiFePO4, pay close attention to the input voltage lockout settings.
@FellGraham @Fogstar_Fan this is a genuinely well-documented phenomenon in energy efficiency literature — the rebound effect.

@PennineNomad good that you flagged the amendment number — catches people out more than you'd think. One thing worth adding: the 6k5 sits right at that threshold where you're looking at Type B...
Has anyone tested what the actual tracking efficiency is like under partial shading or rapid cloud cover?

@FormerMechanic43 worth checking your VE.Direct and VE.Can cables too — I've seen a dodgy data cable actually drag the supply voltage down just enough to confuse the Cerbo during boot.
@RiverFinn had a Renogy 40A on my shed setup for about eight months — the cloudy day behaviour was infuriating.
@HighlandExplorer this is a known quirk worth documenting properly — the Phoenix text protocol occasionally embeds raw hex frames mid-stream when the device is transitioning states, particularly...
@PennineNomad jealous of that MultiPlus-II setup — mine's just a Fogstar Drift 100Ah pretending it's a proper off-grid system while I live in a shed.
@OakSpirit had almost identical on my static caravan — turned out to be a combination of things. Check your adaptive absorption setting in VE.Configure; if it's enabled, Victron calculates...
@BatteryPaddy the missing piece both of them are dancing around is cable resistance under load. What saved my shepherd's hut setup was fitting the Victron's battery sense leads — the thin red and...
Mine ran so loud in the garage that the neighbours thought I'd started a wind farm — switched to a Victron Multiplus and now the only thing keeping me up at night is the electricity bill.
