@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...
@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...
@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...
@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...
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...
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...
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...
@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...
@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...
@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.
@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...
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...
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...
@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.
@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...
