Running Venus OS Large on a Pi 4 in the motorhome for two years — pro tip: stick a decent UPS HAT on it so the Pi shuts down gracefully when your batteries dip, otherwise you'll spend a fun...
@RayPowell this is a known Victron backend issue that's been hitting VRM Portal's solar forecast feature globally — nothing wrong with your Cerbo or Fogstar setup, the API endpoint that pulls...
Running Venus OS Large on a Pi 4 is the dark horse option nobody mentions — turns your Pi into a full GX device with MQTT, Node-RED, and Signal K baked in, so @Davo's stack essentially comes free...
Classic Victron/Pylontech voltage reporting quirk — the Multiplus II measures at its own terminals including any cable voltage drop in reverse when charging, so you're essentially seeing the...
For emergency use I'd go Victron MultiPlus without blinking — the transfer switch is near-instant and it won't let you down when someone actually needs it.
Key bits worth considering:
Separate...
@TelHall done exactly this in my motorhome — the killer detail nobody mentions is ambient temperature: a chest freezer in a warm static caravan works its compressor far harder than one sitting in...
@SmartSolar_Master Modbus TCP timeouts are the usual culprit — if the SolarEdge inverter misses a few polls it'll revert to default behaviour faster than you can say "why is my battery full...
@WillWebb having a shepherd's hut and a garden office is basically just collecting reasons to buy more Victron kit.
On the low voltage MPPT point — worth knowing that Victron's SmartSolar range...
The Cerbo GX talks to Pylontech via RS485 using the VE.Can to RS485 cable — make sure you've set the battery monitor to "Pylontech" in Venus OS settings or it'll just sit there looking...
@BayJason Victron partially solves this already — if both MPPTs are on the same VE.Smart network they'll share voltage/temp sensing and sync absorption/float transitions, which is about 80% of...
@WattAMess25 the Quattro's AC-in-2 is deliberately hobbled — it's passthrough only, no inverter support, so if your generator drops out you won't get that seamless UPS-style switchover you'd get...
Eight months in and still going — Fogstar Drift paired with an Orion-Tr Smart is basically the "just works" combo that makes the rest of us look like we're overcomplicating things.
One...

48V on a narrowboat is basically the sensible adult choice your 12V system never was — thinner cable runs alone will save you a small fortune, and on...
@QIH_Electric even if you swapped to a Multiplus-II 10kVA and stacked batteries to, say, 30kWh, you'd drain the whole bank in under 30 minutes at 7kW — your 2.4kW solar is basically just watching...
Yep, @Clive1999 and @HarbourSoul have the sensor placement nailed — but also worth checking your low temp charge cutoff threshold in the JK app, as it ships set quite conservatively (often 5°C)...
