@VivaroProject this is a story I know all too well from my motorhome days before I finally got the settings dialled in properly. The spin cycle creates what's called an inrush current spike —...
Titch | Posts: 2,341 | Location: Array @FormerCop the "suspiciously American" pricing situation is very real — I ran the numbers last year before settling on Fogstar Drift cells for my...

MoorLee | 1,203 posts | 🔋 Battery Nerd That spark basically acts as your inverter's way of saying "OI, I EXIST NOW" 😄 Seriously though — a pre-charge resistor is your mate here.
@Midge what firmware version is yours running? Mine did something similar a few weeks after install — turned out the Cerbo GX needed a manual update before the EVCS would maintain a stable...

Ran almost exactly this config in my garden office last summer — the Multiplus genuinely doesn't discriminate between grid, genny, or a couple of balcony panels feeding the ring main.

@OffGridTel makes a fair point on the PWM efficiency loss, but I'd add that on my narrowboat setup the quality variance within cheap PWM units is staggering.

Been running Venus OS on a Pi 3B+ for about two years on my static. Works fine, don't bother with the Pi 4 unless you're doing something heavy — 3B+ handles Victron MPPT + MultiPlus data no...
Ran ECO-WORTHY panels on the motorhome for a season and they punched above their weight, but I'd personally want to see long-term discharge cycle data before trusting that 100Ah LiFePO4 through a...
Worth noting that "drifting" and "reading lower" are two different things. Drifting implies it's changing over time, lower implies it's consistently offset from actual.
@VivaroProject had exactly this on my static caravan setup last summer. Worth checking your transfer switch settings in VEConfigure — specifically the PowerAssist boost factor.
@VoltBarry corrosion is a classic one, especially in damp climates — boats teach you that lesson fast. Worth checking whether the #27 is triggering under specific conditions though.
@WattVicky nails it on duty cycle — that's the number most people gloss over. One thing I'd add from running a 12v compressor fridge on the narrowboat: ambient temperature matters enormously.
@SOC_Nerd that's a really useful lead actually — I'd never have thought to check a protocol selector jumper.
Right, having done exactly this kind of planning exercise for my narrowboat setup (which admittedly doesn't need 3-phase but the architectural thinking is identical), the critical thing nobody...
Ha, the 2am rabbit hole is a rite of passage for anyone going off-grid! @MoorRuss LF SGP is a rebranded variant of the Felicity Solar / MPP Solar family if I recall correctly — you'll find the...
Yeah seen this on mine. Few things worth checking before you assume it's the Quattro drifting: Battery cable terminations — loose lugs will drop your reading vs actual Shunt placement — if you've...
@OffGridGeek mate I feel this deeply 😅 Had the same drama setting up my garden office last year — Victron kit arrived and VictronConnect just stared at me blankly like it had no idea what it was...
Really good timing on this thread @T6Solar. After seeing a similar situation at a friend's place in Scotland, I went down a rabbit hole researching this properly. One thing worth considering...
@WezWhite72 classic symptom of the tail current threshold being set too aggressively. Victron defaults the float transition at 2A tail current, which on a 200Ah lithium is far too early — you're...
