SSH removed from Cerbo 3.81?
Worth noting this is in the wrong forum — nowt to do with batteries or BMS, should probably be in Victron/Monitoring. That aside, @LutonDream has pointed you at the right toggle.

Shed office build - worth going for 3 phase or overkill for just a couple of monitors and a kettle?
@OldSailor78 pretty much nailed it. 3 phase for a shed office is madness unless you're hiding a CNC machine in there. Single phase with a decent Victron inverter and some solar panels will handle...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@LiFePO4Nerd curious what you were about to say there mate, post got cut off. My take — the BMS SOC is often just guesswork based on voltage, which is basically useless on LiFePO4 given that flat...

Anyone else using a Raspberry Pi to log their victron data locally?
HarbourHermit | 312 posts | ⚡ Solar Addict Running a Pi 4 locally here too but went a different route — Grafana + InfluxDB pulling from the Victron MQTT broker.

Unable to load Superpack back to 100%
Worth checking your DC-DC charger's charge profile is actually set for LiFePO4 and not AGM/gel. Seen this catch people out more than once — absorption voltage sitting too low (like 14.1V instead...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
What @Paul1999 is getting at is the key bit — SmartShunt is coulomb counting, BMS is doing cell voltage balancing.

BMV-712 phantom current
Been scratching my head with mine lately so figured I'd start a thread. Running a Victron BMV-712 on a 12V 100Ah Fogstar Drift LiFePO4 in my harbour setup.

RVPOZWER 12V Lithium Battery 100Ah $99 ,48V 100ah $432
@LesWood78 curious what you found inside — dodgy cells or the BMS that was the weak point? Either way, avoid.

Anyone else noticed their electricity bills absolutely rocket this month?
Charging the EV off solar has basically made petrol station anxiety a distant memory. @BenJackson gets it. My setup's nothing fancy — just enough panels to keep the car topped up most of the year.

Multiplus II erratic behavior during transitions
@VoltJohn had exact same setup last winter — Multiplus II 3kVA with a Fogstar Drift 48V. What fixed mine was tightening up the battery communication settings in VE.Config.

Industrial Microgrid Design: Solar VFD Loads First, Export Excess PV to Generator-Based Grid
Been thinking about this setup a lot lately after chatting with someone running a small fabrication workshop off-grid. The concept is solid — prioritise your heavy three-phase VFD loads directly...

Wired up a 400W solar array to my garden office last month — here's what I learned
Running a similar rig for EV top-ups on a Leaf — same Victron controller, pair of panels. One thing nobody's mentioned: shade matters more than you'd think with a series string.

Anyone else running lithium on a narrowboat? Swapped out my lead-acid bank last month and a bit confused about charging sources
@GillWard Worth adding — your solar situation matters a lot here. What panels are you running and through what controller?

Anyone else had their BMS cut out mid-storm when they needed it most?
@KevLee seen this exact scenario. My Fogstar did something similar last winter — turned out the cell voltage imbalance had been quietly building for weeks and the storm conditions just pushed it...

Anyone else finding the Victron Orion-Tr Smart a bit oversized for a small van build?
Ran a 12/12-18A non-isolated in my setup for ages before upgrading. Honestly? The 30A earns its keep faster than you'd expect once you're running bigger loads off the leisure bank.
