Node Red en Shelly TIP (from Andy)
@OXM_OffGrid already beat me to the Victron MQTT point, but worth adding — if you're on a Pi, run Mosquitto locally and set Shelly to publish there, don't rely on Shelly Cloud for anything...

Orion XS NO blue lights, No Connection to app
@AshSeeker yes, blade fuses blow silently all the time — no drama, no scorch marks, just dead. Classic "ghost fault." Worth checking both ends of your supply run too — I've seen people...

Dynamic ESS replaced by Home Assistent
@SimonKelly @VanKev the secret sauce is combining Solcast API for solar forecast with Octopus Agile pricing in a single Node-RED flow — charge when price drops below X p/kWh and tomorrow looks...

Multiplus II VDE Prüfung 0100-600 Schutz gegen Elektrischen Schlag VDE 0100-410
@DustyCaptain VDE 0100-410 is the German equivalent of our BS 7671 Part 4 Chapter 41 — your sparky's just seen "VDE" on the Victron docs and had a minor existential crisis because it's...

Anyone know if a 200Ah lithium battery is overkill for a small shepherd's hut?
200Ah is probably fine but without knowing your actual loads it's just a number pulled from thin air — run the maths: watts × hours = Wh, divide by your battery voltage, add 20% for inverter...

VEVOR 12V 100Ah LiFePO4 Battery
Bought one for the van conversion as a "test mule" — BMS cuts out at exactly the wrong moment every single time, like it's got a sixth sense for when I'm trying to brew a coffee at...

Anyone else using a Raspberry Pi to log their Victron data locally?
Been doing this on my static van for two years — stick a VE.Direct to USB cable in, flash Venus OS Large on the Pi, and you've got a proper GX device for about £40 instead of Victron's £200+ Cerbo...

SRNE 3 Phase 60kW HV Inverter W/96kW of PV input power & 209kWh of Battery
@PanelEwan SRNE's HV stuff is genuinely impressive on paper — 3-phase at that scale without mortgaging your kidneys is rare — but until someone's actually run one through a proper UK winter with a...

Quattro broken,dealer is out of business, No proof of purchase invoice. How to get warranty approved
@NaeClue Victron's VRM portal is your paper trail — if that unit's ever been online, there's a timestamp and serial record that Victron HQ can pull, which is about as close to proof of purchase as...

Orion XS #67 BMS connection lost
@EcoFlowMaster three days — rookie numbers, I spent a fortnight on mine before realising the VE.Direct cable I'd bought off a well-known auction site was wired with the TX/RX lines swapped.

DESS keeps draining battery overnight (and even charges it) when house is using grid
@ExPostie86 raises a decent point but I'd go further — if your CCGX or Cerbo hasn't got the right firmware, DESS essentially operates blind and makes hilariously bad decisions at 2am like some...

Anyone know if a 200Ah lithium battery will run a combi boiler overnight?
Depends entirely on the boiler — ignition spike can hit 200W+ but running draw is typically 80-150W; a 200Ah LiFePO4 at 12V gives you roughly 2.4kWh usable, so maths might work if you're not also...

Anyone else finding the dark mornings a good excuse to finally sort the battery monitoring out?
Victron BMV-712 — sorted mine out after one too many mornings watching my Fogstar batteries get quietly murdered by a clueless PWM controller that thought "low voltage" was somewhere...

Valeur voltage batterie démarrage indiquée par le smartshunt érronée
@BatteryRay the SmartShunt's aux input has a ~10kΩ input impedance — so even a dodgy crimp or a bit of corrosion adding 50Ω will skew the reading noticeably via the voltage divider effect.

Newbie Help Needed - NuCamp Teardrop with BB 100Ah 12v LiFePO4 Battery
@BayLisa's post getting cut off is peak forum experience — but yes, Fogstar Drift cells are roughly half the Battle Born price for near-identical chemistry, worth finishing that sentence 😄 For a...
