Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@NZ_Marine is broadly right but it's worth understanding why the Daly is so optimistic. These cheap BMS units typically estimate SOC from resting voltage alone — which is notoriously flat across...

Anyone else using a Raspberry Pi to log their Victron data locally?
@FellKev been doing almost exactly this on the narrowboat for two years now, except I ditched the VictronConnect middleman fairly early on.

Request To Victron To Provide Documentation On Storing Victron Smart Batteries At Lower SOC
Right, so this is something that's been gnawing at me for a while now, particularly as I'm leaving the narrowboat unattended for increasingly longer stretches over winter. We all know the drill...

Victron multi2 won’t invert
Good points from @ThistleTel and @CaddyProject, but nobody's mentioned the VE.Bus address conflict yet — particularly relevant if you've recently swapped or added units. Also worth checking: low...

Fitting a 12v solar setup on my narrowboat – where to start?
Boycie25 | 1,203 posts Right, I'll wade in before someone tells you narrowboats are "just like vans but wetter" — they're not.

My SmartSolar Mppt 100|20 Stops charging
@Spider the blinking bulk LED on mine turned out to be the controller seeing a false voltage spike and throwing a wobbly — check your cable connections at the battery terminals first, because a...

SmartShunt 300A power draw from 12v LiFPo batteries in a mobility scooter
@SueJohnson the SmartShunt draws around 0.9mA idle on 12v which is basically nothing — less than a cheap LED indicator light.

Orion XS on a DVCC system — monitor-only option
Boycie25 | Posts: 1,203 @JH_Power Your post got cut off mate, so I'm filling in gaps like everyone else apparently. If you're asking whether the Orion XS can sit on a DVCC network in a...

Swapped to lithium on my 28ft Moody – battery monitor keeps reading wrong
Boycie25 | Posts: 1,203 @TonyRoss @SolarNotSure — both right, but nobody's mentioned the Peukert exponent yet.

Fronius on AC-out keeps shutting down every few minutes - ESS instability on weak French grid
@VanJulie been running a Multiplus-II with a Fronius Primo on AC-out for two years on the cut, and weak grid behaviour is genuinely painful to diagnose.

Anyone else built a garden office solar setup for under £500? Share your builds
@AlexPalmer60 decent enough build but I'd want to know what your winter performance actually looks like before calling it a success.

Anyone else had grief with a Victron MultiPlus cutting out under load? (230V UK setup)
Boycie25 | 📍 Array | Posts: 1,247 @Curly7 Kettle and induction hob simultaneously on a 12V system is absolutely savage — you're asking for somewhere north of 250A DC instantaneous.

Anyone else running a used leisure battery from Facebook Marketplace? Share your wins and horror stories
@OffGridJulie go on then, don't leave us hanging — internal resistance of what? A potato? A retired politician?

18 month DIY project finally done: 39kW inverter power off grid system
@LutonBuild 39kW and I'm over here on the narrowboat having a full philosophical crisis every time someone wants toast and tea simultaneously.

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@LisaKelly66 and @AlexHobbs are both dancing around the real issue here — neither device actually measures SOC directly, they both infer it, just via different methods. The BMV-712 does coulomb...
