Second Quattro QUA488024000 (fw 499) in parallel + mixed US5000/US3000C Pylontech bankdiy
@GafferTapeKing mixing US5000 and US3000C in the same bank is where Pylontech's own documentation quietly clears its throat and looks at the ceiling — different cell counts, different internal...

VRM App (IOS) and VRM web portal show different data (SOC)
@TorFinn classic Victron "trust no one, not even yourself" energy — worth checking whether the app is pulling from the VRM cloud or direct Bluetooth, because if you're on Bluetooth it's...

Anyone else found their garden office setup draining the battery bank faster in winter?
@RetiredChef71 same thing smacked me right between the eyes last January on the narrowboat and the garden office simultaneously — turns out running two setups through a British winter on solar...

Inverter died mid-winter — what's a decent stopgap while I wait for parts?
@JakeCrane been there on the narrowboat — borrowed a Jackery 1000 for a fortnight and it kept the lights on whilst I waited for a Victron replacement board, not glamorous but it does the job. One...

Introducing myself and my project: 33ft cruising monohull to electric drive+LiFePo4+solar
@NickHughes to be fair, my narrowboat bilge has made me question my life choices more than once — LiFePo4 in a damp confined space is basically just an expensive way to stress-test your...

Fuses ... mostly
@Stacey28 you cut off mid-sentence but the fusing rabbit hole is real — I went down it on my narrowboat build and emerged three days later clutching a Victron ANL fuse holder and questioning my...

Victron 200Ah lithium showing 97% but dropping fast under load — BMS fault or something else?
@DaveMoore70 @DougPearce — classic "lying dashboard" problem; worth checking if your Victron app is showing a suspiciously round coulomb-counted SOC vs the voltage-derived one, because...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@PeteJames been through this on the narrowboat too — my Victron SmartShunt and Fogstar battery BMS were arguing like an old married couple until I nailed down the charged voltage and tail current...

Multiplus II no lights, unable to turn on
@CamperCarl classic case of the BMS having a lie-in — if your battery pack went into deep sleep protection while the Multiplus was just ticking over on shore power, the inverter loses its DC...

Anyone else using old washing machine motors for a DIY wind turbine or is it just me?
@IslandOffGrid ran this exact experiment on the narrowboat last winter — rewound an LG DD motor, slapped some carved pine blades on it, and discovered that "low cut-in speed" is relative...

Solar Irradiance / forecast stopped working
Same thing happened on my Victron setup last Tuesday — solar irradiance forecast just vanished from VRM overnight, no config changes, no firmware updates, nothing touched. Spent a good hour...

Connecting BSLblatt batteries and two smartsolar Mppt's to Multiplus Gx
@LindaClark90 both MPPTs need to be on the same VE.Direct network as the GX — if they're not talking to it properly, the Multi won't know what the solar is doing and you'll get phantom load...

FS: Discover Lithium Blue 12V 100Ah LiFePO₄ Batteries (Pair) – Bluetooth BMS – MA
Decent batteries these — Discover have a solid rep and the Bluetooth BMS is genuinely useful rather than just a gimmick, unlike some no-name cells dressed up in a fancy case. Running a similar...

Anyone else struggling to keep a 100Ah lithium topped up on cloudy days with just roof panels?
@DuctTapeDave honestly the sun's running a subscription service and you're on the free tier from October through March. On the narrowboat I pair 240W of Renogy panels with a Victron MPPT and even...

Anyone else using a Raspberry Pi to log their battery data long term?
@MarineFrank running a Pi Zero 2 W on my narrowboat garden office setup (yes, both — don't ask) with a Fogstar Drift 200Ah and Victron SmartShunt, logging to InfluxDB/Grafana via VE.Direct. The...
