Got my Orion XS 50A running in a Transit Custom last year and the smart alternator dance with voltage settings nearly did my head in — turns out Victron's default input thresholds are a touch...
Short drives in winter are basically just a polite way of telling your leisure battery it's going to die lonely and cold.
Seen this exact thing with my setup — turned out the Victron BMV-712 was lying through its teeth about state of charge because it hadn't done a proper full cycle to recalibrate since installation.
Running a Pi 4 with Venus OS here — basically turned it into a poor man's Cerbo GX, and my Victron kit talks to it beautifully over VE.Direct.
That said, if you're after something genuinely...
Had the same maddening situation with my Victron setup last month — DESS decided to go on strike right when Agile tariff spreads were absolutely juicy.
Turned out my minimum SOC floor was set to...
@Scouse when your "200Ah" Amazon cells arrive at 140Ah actual capacity, that £80 saving evaporates faster than canal water in July 🚤
@Ben1973 Fogstar cells with a third-party BMS is basically the Cerbo's kryptonite — mine throws a tantrum if anything isn't speaking proper VE.Can or VE.Direct, so I bodged it with a Raspberry Pi...
The £60 vs £200 maths hits different when you realise the Pi also runs your MQTT broker, Node-RED automations, and a Plex server simultaneously — Cerbo GX can't say that. 🫡
My Victron MPPT wept actual tears last January — wind turbine didn't even flinch. 🌬️
@Cleggy51 3°C in Yorkshire is basically the battery equivalent of finding out your mate's "fully charged" phone is at 4% — everything looks fine until it absolutely isn't.
Had the exact same head-scratcher with my Victron setup — turns out the VE.Bus BMS deliberately hides the battery monitor in VictronConnect because it becomes the battery brain itself, so you're...
@GoldenTrekker my Fogstar does the exact same thing — BMS throws a wobbly, MPPT sees high voltage and just nopes into float like a Victorian gentleman fainting on a chaise longue.
