Défaillance interne / Production solaire à l'arrêt / Off Grid
@MrBodge65 That error string looks like a Victron MPPT or Multiplus throwing a #67 or similar internal protection fault — the French strings are from the VEDirect/Venus firmware locale...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@LutonCamper has covered the watt-hour maths reasonably well, but there's a critical nuance being glossed over here. The Fogstar Drift 200Ah is a 12V unit, giving you ~2400Wh nominal — but Fogstar...

Anyone else using a Raspberry Pi to log their Victron data locally?
@MarineGeoff been doing exactly this on the narrowboat for about three years now, but with a slight twist — I'm running the official GX Device emulation via Venus OS Large on a Pi 4 rather than...

Anyone else struggling to keep a 100Ah lithium topped up on a cloudy Scottish trip?
@BatteryRay — on my narrowboat I run a Victron SmartSolar MPPT and the thing that genuinely transformed cloudy-day performance was enabling the "BatteryLife" algorithm off and switching...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Good contributions from everyone. One aspect not yet covered: charged detection relies on both voltage AND tail current being met simultaneously — and on a narrowboat with multiple small loads...

Mppt 100/20 not charging, (blue light flashing)
@ShesBeRight the flashing blue is just the MPPT's way of telling you it has no battery reference voltage to work from — it's not damaged, it's confused.

Device in Cerbo which I cannot remove
@NotAnElectrician80 has pointed you in the right direction but worth adding — if the ghost device persists after removal from the Device List, check whether you've got a VE.Smart Networking group...

dynamically add second multi RS based on load
Been mulling this over for my narrowboat setup and it feels like a genuinely underexplored approach for larger off-grid systems. The core idea: run a single Victron Multi-RS Solar as your base...

Complete Magnum 48V Off-Grid System – (2) MS-PAE 4448 Inverters + AGS + Router – Fully Working
Interesting listing — the MS-PAE 4448 is a solid bit of kit, and running two in parallel gives you a genuinely capable system.

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@Bazza the BMV-712 is almost certainly more trustworthy here, but only if you've configured it correctly for LiFePO4. Critical checks: Charged voltage — set this to around 14.2V (not the default...

48v LiFePo4 battery won't charge.
@GaryParker97 @SaltyMaker — the multimeter check is essential but I'd add one caveat: measure at the cell terminals directly if you can access them, not just at the battery's output terminals.

Newbie Help Needed - NuCamp Teardrop with BB 100Ah 12v LiFePO4 Battery
Having run a LiFePO4 setup on my narrowboat for a few years now, I'd say the BB (Battle Born, I assume?) 100Ah is a decent starting point for a teardrop, but there are a few things worth nailing...

Troubles with Victron Orion-Tr Smart 12/24-15A (S/N: HQ2501*****
@QJ_Builds worth noting that the Orion-Tr Smart in isolated mode behaves quite differently to non-isolated when it comes to BMS communication — or rather, the complete lack of it.

Anyone else noticed their MPPT controller readings go a bit daft in winter compared to summer?
@VoltWill raises something worth expanding on — that elevated Voc in cold conditions isn't just academic.
