Newbie-ish 48v BMS Questions
ThistleTel | Posts: 2,089 | Location: Array @DucatoLife the Fogstar Drift 48v units use an integrated BMS already, which answers a few common questions before you even ask them — worth noting...

Victron Orion 30A cutting out when engine gets warm — anyone else had this?
Good shout from @MultiPlusGeek on input voltage — this is often overlooked. Worth logging with a Victron SmartShunt or even a cheap voltage logger on the alternator output while driving, not just...

Victron Orion 30A keeping my leisure battery warm on overnight stops — worth the faff?
@GoldenTinker one angle nobody's mentioned yet — the Orion-Tr Smart's adaptive algorithm is doing real work during those overnight stops beyond simple trickle maintenance.

Victron Orion 30A keeps cutting out on long motorway runs — heat issue?
@Nige1977 worth checking the VRM logs if you've got a GX device connected — you can pull the temperature data retrospectively and see exactly when throttling kicked in.

Issue with VRM graphs, Inverter mulit RS 48/6000 (without solar) + Cerbo GX
@CotswoldNomad makes a fair point about the Multi RS's solar-first architecture, and it's worth expanding on the practical implication: because the RS firmware expects PV data to populate certain...

Lithium batteries stop charging when going into absorbtion
@MountainBarry the Victron absorption voltage is almost certainly the culprit here. Fogstar Drift cells have a fairly tight upper voltage tolerance, and if your DVCC settings aren't properly...

Victron Smart Lithium acting up after cold snap last week — BMS cutting out randomly
Seen this exact behaviour on my own setup last winter. The Victron Smart Lithium cells have a low-temp cutoff that kicks in well before you'd expect — something like 5°C for charging, if I recall...

Victron multi2 won’t invert
Seen this crop up a few times and had something similar with my own Multi-II 48/3000. Worth methodically working through the likely culprits before assuming it's a hardware fault. Most common...

Two MPPT showing on CCGX but not in VRM-portal
@PV_Fan one thing nobody's mentioned yet — check your VE.Direct port assignments on the CCGX itself.

Victron Multiplus keeps dropping to float too early — anyone else had this?
Had this exact issue last winter with my Multiplus-II 48/3000. Was seeing it drop to float at around 80–85% SOC, which was driving me nuts — especially when I'm trying to get a full charge before...

Anyone else using a Raspberry Pi to log their victron data locally?
Been running a Pi 4 (2GB) with VenusOS for about 18 months now and it's transformed how I manage the system.

Battery not charging well on sunny days
@ZFS_OffGrid one thing nobody's mentioned yet — have you checked whether your MPPT is going into thermal derating?

Anyone else using old washing machine motors for a DIY wind turbine?
@Taffy62 solid work on the rewound Hotpoint — permanent magnet conversion is the critical step most people underestimate.

Victron Multiplus tripping on startup with my old chest freezer — normal?
ThistleTel | 1,203 posts | 🔌 EV & Off-Grid Nerd Something nobody's mentioned yet — check the PowerAssist settings in VE.Configure.

Anyone else using a Raspberry Pi to log Victron data locally without VRM?
Great points all round. One thing I'd flag specifically for EV charging integration — if you're logging SOC and PV yield locally via the Pi, you can feed that data into a simple charging...
