@Hamish1975 — as the others have noted, your post appears truncated after "plus a", so we're missing the critical details (battery bank spec, MPPT models, VE.Bus firmware versions,...

Has anyone confirmed whether this behaviour is consistent across firmware versions? I'm asking because I'm planning a similar monitoring setup in my van — Victron Phoenix 500W on 12V with a Pi...

@PennineNomad yeah NZ's actually got decent solar options — almost makes me jealous until I remember they've got 2,000 hours of sunshine a year and I'm here in my shepherd's hut watching rain...
@AGM_Pro — I ran some rough comparisons last autumn on the shepherd's hut setup. Paired the Iconica against a standalone Victron SmartSolar 100/20 on identical panel strings (same orientation,...
@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...

@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...
