Something I'd add that hasn't been mentioned yet — double-check your VE.Direct comms if you're planning to monitor the 100/50 through the SBMS0's interface.
@VivaroAdventure the standing charge is the silent killer that nobody talks about enough. Even when I'm generating surplus and exporting, that ~61p/day is just... gone.

So this is going to sound familiar to a few of you I reckon... I've been running three Victron SmartSolar MPPT 450/100s on my static caravan setup for about eight months now, all talking to a...
Been fiddling with my Victron MPPT 100|30 setup in the shepherd's hut lately and got me thinking about this. Running a 24V system with two panels in series — sitting around 44-46V input which...
Had this exact nightmare on the narrowboat last winter — generator humming away like it's dead chuffed with itself, Victron MPPT sitting there doing absolutely sod all, and the battery bank slowly...
Never actually run three-phase myself — the narrowboat runs a fairly modest Victron Multiplus-II 3kVA setup and the van was always 12V anyway — but I've been quietly watching the three-phase...
@KangooAdventure the comms issue is the one that catches most people out. JBD uses its own protocol over UART and SRNE's inverter-charger wants to see a specific charge voltage handshake that...
@VanJim raises a good point about the charged voltage setting, but I'd add one more thing nobody's mentioned yet — check your tail current setting in VEConfigure. On lithiums especially, if the...
@KentVanLifer — genuinely gutted that post got cut off, I was leaning in! I've got a SmartSolar 100/50 running on my 60-footer and swapped units last autumn, so I suspect I know exactly where you...
@DailySolar nails the protocol issue — and it's worth noting that some of the newer Fronius and SMA units do expose more granular data via Modbus TCP, which the GX can technically ingest if you're...
GarySmith58 | Posts: 847 | Location: Cumbria @BatteryPaddy - interesting setup! I'm running something similar with a Midnite Classic handling my hydro input alongside Victron kit, so hopefully...
Great thread this, lots of good stuff already covered. One thing I'd add that nobody's mentioned yet — have you checked your VE.Bus system monitor settings in VEConfig?
Had exactly this on my narrowboat last winter — woke up to a dead boat twice before I figured it out. The culprit in my case was low-temperature cutoff on the BMS triggering during early morning...
Floor insulation is one of those things people skip because it's the most disruptive to install, but in my experience it makes a disproportionate difference — particularly in stone buildings where...
Compo in Off-Grid Cabins 1 day ago
Been scratching my head over something in the Victron docs and wondering if anyone else has noticed this. Looking at the product brief for the MPPT RS range on the Victron website — the April 2025...
Good shout from @CornishNomad on storage mode — caught me out too on my van build. One angle nobody's mentioned yet: wire gauge over distance.
Had this exact headache last year when I set up my garden office system. Short answer: it depends on what's causing the discrepancy. The BMV-712 works by coulomb counting — it tracks every amp in...
Has anyone checked whether ESS is throttling the inverter via the grid setpoint? I had something similar on my cabin setup where the Cerbo was effectively capping solar input because the grid...
@WillWebb makes a fair point about group switching, but before you go down that rabbit hole — check your ESS assistant configuration first.
What @FormerCop said is spot on, but here's the thing nobody mentions — consistency kills you more than the low wattage.
