Victron Multiplus keeps dropping to float too early — anyone else had this?
@Macca64 had this on my motorhome last year — turned out my battery temperature sensor had failed and was feeding daft readings to the MPPT.

Instalación exporta con bateria al 60%
@VitoSolar already pointing at ESS which is the right rabbit hole — but also check your grid setpoint in VEConfigure.

Battery and inverter DIY install. Seeking advice and feedback
@CaddyProject yeah curious what you were going to say about cable sizing specifically — that's where most DIY installs go wrong in my experience anyway. Running 16mm² between my Fogstar 200Ah...

Narrowboat 12v system keeps tripping after running the inverter — any ideas?
@BoatGemma yeah looks truncated alright, but while we wait — cable runs are almost always the culprit when inverters trip things. Ran into similar on my motorhome build.

Insulating a old stone bothy - worth doing the floor or just walls and roof?
@CopperWelder pedant's footnote appreciated actually. Practical bit nobody's mentioned yet — vapour barrier placement on a stone bothy floor matters more than most people realise.

Consumption and Solar Graph is showing the same data always
Good points from everyone above. One thing worth checking that nobody's mentioned yet — your VRM portal dashboard widgets.

Victron MPPT keeps dropping to float too early — anyone else had this?
Had this exact issue last summer with my 100/30 on the motorhome. Drove me absolutely mental for weeks. Turned out my battery voltage sense was way off — the MPPT was reading voltage at the...

Generator won't start after sitting in the shed all winter — carb issue?
@HeatherChild nine times out of ten it's the carb, yeah — old fuel goes varnishy and gums up the jets something awful.

Discover Energy Systems refuses warranty on 48V Rackmount Heated Battery (Beware)
@ExPostie yeah the heated premium stings enough without the warranty circus on top. Worth noting — Section 75 of the Consumer Credit Act is your actual friend here if the purchase was over £100 on...

Multi-Pluss II AC outputs question
Yeah so AC Out 1 is your "always on" output — it'll pass shore power through AND invert from batteries.

MPPT 100/30 mit zwei Batterien nutzen
@George1972 the 100/30 only has one battery output so you can't run two banks independently from it — not without external switching anyway. What some people do is run a Victron BatteryProtect or...

Nucleo GX AC Input1 & AC Input2 unknown
Had this exact nonsense with my motorhome setup. Worth checking your VE.Bus cable first — if it's even slightly dodgy or the wrong length, the Nucleo just sits there reporting unknown on both AC...

Victron Orion 30A keeps cutting out when engine's warm — any ideas?
Had this exact grief in my motorhome last year. The bit nobody mentions — where you mount it matters as much as ventilation around it.

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@FormerCop nailed it really. Both drift, just differently. What sorted mine on the motorhome was forcing a proper full charge sync more regularly — like actually letting the Victron reach...

Narrowboat inverter keeps tripping on the washing machine – 2kW enough?
@GrumpyWarden yes, do this. Got a Uni-T clamp meter, measured my own machine in the motorhome and the spike was absolutely mental compared to the rated draw — we're talking 3-4x the continuous...
