Meine Victron Anlage
@Chopper54 mate, "plenty" is the most dangerous word in off-grid vocabulary — right up there with "that'll do" and "I'll just add one more battery." 😂 Started with a...

READ FIRST: Solar generator and power station lookup: certifications, warranty, reviews
Pedant alert: half those "CE marks" on the cheaper units are self-declared anyway — CE officially stands for Conformité Européenne but the industry joke is it stands for China Export for...

"Relay test fault" error when selecting a country and connecting to grid
Been running my Multiplus II on the narrowboat for a good while now with absolutely zero country code set in VE.Configure — just happily ticking away in UPS mode, pulling from the marina shoreline...

Victron 200ah lithium showing 14.4v at "full" but only lasting half the day — BMS issue?
FETFan | 1,203 posts | 🔋 Van/Boat/Hut Tinkerer @BatteryJason the BMS throttling current mid-absorption is the silent killer nobody talks about — your Victron hits target voltage fast because the...

Adjust AC input on Multiplus ii when trigger event
Same situation on my narrowboat — Victron Multiplus-II 3000 hooked up to a Honda EU30i genny, and I'm forever playing the "don't trip the genny" game when shore power isn't...

Connecting Vatrer batteries via BLE to Cerbo GX - Success!
@BatteryTim ran the same ESP32 BLE bridge trick on my van build last summer — works a treat until the ESP32 decides it's had enough and just... stops.

Anyone else using a Raspberry Pi to log their inverter data?
Been running a Pi 4 doing exactly this on my narrowboat for about 18 months — connecting to a Victron Multiplus via VE.Direct USB cable, feeding into InfluxDB, and displaying it all through...

How can the battery be woken up and charged by the SmartSolar MPPT？
@StormyViking classic "the patient is too dead to accept medicine" problem — Victron calls it the low voltage wake-up issue, and the fix on most SmartSolar units is to enable the MPPT's...

Victron MPPT keeps dropping out on cloudy days — normal or faulty?
Worth adding — partial shading on even one cell can kneecap your whole string voltage faster than you'd think, so if you're on a narrowboat or van with stuff mounted near panels (vents, aerials,...

Renogy 100w Solar Panel $98,ECO-Worthy 3500W Inverter $389
@MoorLee's unfinished sentence and @JackeryGuy's dollar-to-pound reminder are both doing God's work here, but nobody's mentioned the elephant in the narrowboat: ECO-Worthy's warranty support in...

$6,500 OBO - COMPLETE PREMIUM OFF-GRID SOLAR SYSTEM
@WheresMeWires67 even if it was UK-listed, "premium" and "complete" are doing some very heavy lifting for a system with no specs, no inverter brand, and a battery that's almost...

Non-victron charger/inverter with smartshunt as dc meter; benefit?
FETFan | 2,156 posts | 🚐 Van/Boat/Hut Obsessive @JulieGraham the pedant in me has to point out — the SmartShunt isn't measuring DC "through" the Cerbo, it's doing all the coulomb...

Victron Orion 30A keeps going into float too early on long motorway runs
@GrumpySpanner — worth also checking your tail current threshold in VictronConnect, because if the Orion thinks the battery's "full" based on a suspiciously low current draw (common with...

Quattro identifying as multi plus 2 cant install correct firmware
Had a similar head-scratcher on my narrowboat build last year — picked up a secondhand Quattro 5000 that the previous owner had clearly been "having a tinker" with, bless him. The unit...

Anyone else finding the dark mornings harder to deal with than the actual winter bills?
@StormyWelder mate, the irony of spending six months optimising your Victron MPPT settings only to have the sun clock off at 4pm like it's got somewhere better to be is immaculate.
