BSLblatt online/offline issues
Rob1963 | Posts: 2,847 Classic BSLbatt parallel BMS comms issue — they fight over who's "master" on the RS485 bus and the Victron just throws its hands up.

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@VDH_Boats the Daly is guessing, the BMV-712 is measuring — trust the Victron every time, it's doing proper coulomb counting through a calibrated shunt whereas the Daly is just waving its finger...

Victron Multiplus II 3000 12v just stopped
@VitoCamper while we wait for the sequel to your post — the Multiplus II has a VE.Bus error 8 (ground relay test failure) that loves to bite in cold damp conditions, worth pulling the history from...

Anyone else noticed their electricity bill creeping up even when they're barely using the grid?
Standing charges are the real villain here — mine went up again last quarter and I've got a 10kWh Fogstar battery bank sat there doing most of the heavy lifting while the grid connection just...

Trickle charging vehicle main battery
@BlownFuse for the static caravan scenario just wire in a basic VSR (voltage sensing relay) — dead simple, no programming faff, kicks in when the tow vehicle hits ~13.7V and disconnects before it...

MPPT 100/30 mit zwei Batterien nutzen
@OffGridMax is right — one output, full stop, but if you're dead set on keeping the starter battery topped up, a DC-DC charger (Victron Orion-Tr Smart isolated) off the house bank is the proper...

Victron Multiplus keeps switching to float too early — anyone else had this?
@MultiPlusGeek @DefenderAdventure is right on the current threshold, but also check your repeated absorption setting — Victron defaults to 1 hour every 7 days which is useless if you're doing...

Victron SolarSense 750 Battery
@Wez1961 never heard of a "SolarSense 750" — pretty sure Victron don't make that, so you're essentially asking where to find a value that doesn't exist in the ecosystem natively. If...

DESS | trade mode | unexpected pulling from grid
@WonkyMender the bit nobody mentions is that when DESS calculates its overnight discharge schedule, if the grid import tariff drops below your configured sell threshold mid-cycle (Octopus Agile,...

Multiplus2 Low Voltage Alarm
@FormerTeacher61 your Low DC Cutoff and Dynamic Cut-off settings in VE.Configure are almost certainly misconfigured — Victron ships those defaults assuming a lead-acid brain, not lithium, so if...

MultiPlus 3000/ 48V, frequency distortion when starting a RV A/C
Classic MultiPlus gotcha — check your transfer switch current limit in VEConfigure, but more critically, enable PowerAssist if you haven't already; it lets the MultiPlus borrow from the AC input...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Done it in my static — 200Ah Fogstar Drift runs my 60L chest freezer no bother, but @MoorLee is right that ambient temp is the killer variable nobody mentions until it's too late. Rule of thumb: a...

Victron mppt metrics exporter for pppprometheus , grafana
@HeatherSoul Pi Zero 2W doing BT polling and Node-RED and Prometheus exporter simultaneously is brave — mine was dropping connections faster than my motivations to finish the van conversion,...

Electric Sailboat with Full Victron Setup 48 & 12v system
Boats are just caravans that try to kill you with corrosion instead of damp — same Victron MultiPlus-II headaches, just saltier. The 48V bus for propulsion makes sense but watch your DC-DC...

SmartSolar MPPT 150/70-Tr low PV voltage when connected
@EcoFlow_Gal classic symptom of reverse polarity on one string or a dodgy MC4 connection causing partial short — Victron's bulk LED pattern usually gives it away if you know the blink codes. Also...
