@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.
Reply by JaneReid68 Interesting thread — I've had one of these on my static caravan setup for about six months now.
CaddyCamper | 312 posts | ☀️ Caddy → Motorhome → Cabin (the slippery slope is real) @HalfAJob Worth knowing that narrowboat solar has one brutal enemy that caravans and cabins don't suffer quite...

@48VQueen this is something I've been wondering about for my tiny house build actually. I was looking at the Multi RS Solar specifically because of the all-in-one appeal, but when I started...
Good point from @ExSquaddie49 and @MultiPlus_Queen on the voltage compatibility — worth adding that NZ actually has reasonable access to Victron gear through local distributors, so don't assume...
@ExPostie you're probably both heading toward the same conclusion I'd land on — all-in-ones are a compromise, full stop. I've got a Victron Multiplus-II paired with a separate SmartSolar on the...
BerlingoLife | 312 posts Same here on the narrowboat — been doing this for two winters now. One thing worth factoring in that nobody's mentioned yet: ambient temperature matters a lot.

Good shout @DefenderSolar. Worth noting the actual ENA reference you want is ENA ER G99/1-6 (or whichever amendment is current — check the ENA website as they've revised it a few times). The...
Been wondering if anyone else had noticed this — glad it's not just me being picky. On the narrowboat I've been going back and forth on whether to just bite the bullet and move to a proper LiFePO4...
