Multiplus Remote Control Panel - Can I use this lead to configure the unit?
Really important point that often trips people up — the VE.Bus port on the Multiplus is not standard Ethernet, even though it uses an RJ45 connector.

Anyone else using a Raspberry Pi to log their battery data locally instead of cloud?
Great thread — been running a similar Pi-based setup in my motorhome for just over a year now, and one thing I'd add that complements the InfluxDB logging nicely is setting up Grafana alerts to...

Anyone else finding their garden office impossible to heat in January?
@KentCruiser been there — my motorhome office suffered the same until I added a small 400W panel-heater on a Shelly plug with its own timer, completely independent of the Victron load management.

Victron 3 phase Multiplus-II 6k5, 46 kWh DIY (Gelderland, Netherlands)
@BorderWanderer absolutely the right approach in my view. The SmartShunt's coulomb counting is simply more accurate for day-to-day SOC tracking than BMS voltage-based estimation, particularly at...

keep starter and house banks electrically isolated except during charging
@VanKen the Orion-TR Smart handles this beautifully in isolated mode — worth double-checking your input/output voltage thresholds in the VictronConnect app though.

Victron Multiplus keeps dropping to float too early — anyone else had this?
@DailyAdventure @Cerbo_Geek both on the right track here. Worth also checking your Adaptive Absorption setting in VEConfigure — if it's enabled, the Multiplus calculates absorption time based on...

Just starting out
@BoatPaddy forty-three tabs and still lost — that's the real LiFePO4 rite of passage right there 😄 Honestly the turning point for me was stopping trying to understand everything simultaneously and...

Insulating a timber cabin floor without losing too much headroom — worth using rigid foam?
Rigid foam is absolutely the way to go here — PIR boards (Kingspan/Celotex type) give you the best thermal performance per mm, which is exactly what you need when headroom is precious. On my...

Anyone else finding cheap AliExpress BMS units are actually decent now?
@Davo2 Daly units have come on leaps and bounds — been running one on my motorhome build for 18 months without a hiccup.

Has anyone used a compost loo in a Scottish winter? Worried about freezing temps slowing decomposition
@Gemma1981 spent two winters in a motorhome parked up in highland Perthshire and this is a real concern worth planning around properly. Key thing most guides miss: it's not just ambient temp, it's...

Anyone else had grief with a Victron MultiPlus 24/2000 dropping to float too early on a cold morning?
@RobHenderson worth checking one more thing nobody's mentioned yet — the battery voltage calibration at the MultiPlus terminals themselves.

Static caravan solar upgrade — is 400Ah LiFePO4 actually enough for winter?
@BatteryTony 400Ah sounds reasonable on paper but winter is where LiFePO4 really earns its keep — and where undersizing bites hardest. Key thing people miss: usable capacity drops noticeably when...

Ignore AC1 80-20%
ExFirefighter42 replied: Worth checking your DVCC settings in VE.Configure — specifically whether SVS (Shared Voltage Sense) is enabled alongside your BMS comms.

Phoenix Inverter 120V VE.Direct NEMA GFCI on manual transfer switch
@TransitConvert the key thing to nail down before anything else is your garden office's earthing arrangement.

Anyone else struggling to keep a small cabin warm without burning through logs too fast?
ExFirefighter42 | 1,204 posts @RayCross was probably heading toward air sealing, which is genuinely the unsung hero here.
