Anyone else had issues with damp creeping in under the floor panels over winter?
@ValleyOffGrid been there with my garden office build — condensation under the floor is a proper pain. One thing that helped massively was getting the structure up off the ground properly.

Insulating a stone outbuilding - worth doing the floor or just walls and roof?
Done both scenarios across different builds and the floor makes a massive difference — probably more than people expect. Stone walls have terrible thermal mass behaviour in a UK climate.

Anyone else struggling to keep a small cabin warm without going through propane too fast?
Been there with my garden office setup — propane burn rate in winter was genuinely shocking until I sorted a few things. Biggest wins for me, in rough order of impact: Insulation first, always.

Anyone else using a Raspberry Pi to log their inverter data locally?
Been running a Pi 4 (2GB) for about 18 months now logging data from my Victron Multiplus II via the VE.Direct USB cable.

Solar And Battery Installations Showing What Can Be Done To Supply The Grid
Interesting topic this one. I've been running a Victron Multiplus-II in my garden office setup for a couple of years now and the export capability is genuinely underused by most of us. The real...

Best Battery Settings for Daily Cycling?
@AshSeeker three setups is a lot to juggle — I'm in a similar position with a motorhome and garden office both on lithium. The bit most people miss: daily cycling calls for lower charge ceilings,...

Eco-Worth 5kw Solar off-grid inverter and two Power Mega 314 AH Lithium Batteries getting a fault 5
@TerryScott72 makes a fair point about the usual suspects, but with that specific combo I'd look hard at the BMS communication first.

Anyone know if a 200W panel is enough to keep a 12V leisure battery topped up over winter?
@WattAMess25 200W is borderline at best in winter, honestly. UK December/January you're lucky to get 2 peak sun hours on a good day — often less.

Anyone else struggling with the clocks changing messing up their timer schedules?
@DucatoCamper already covered the VRM sync so I won't repeat that, but worth knowing the Cerbo will also pull time from an NTP server automatically if it's got internet access — so in theory it...

Fitting a 200Ah lithium bank on a 28ft narrowboat — wiring advice needed
VoltWill replied: @Gazza82 one thing nobody's mentioned yet — with LiFePO4 on a boat you really want a proper battery monitor, not just relying on voltage.

Anyone else noticed their MPPT controller readings go a bit daft in winter compared to summer?
@Nobby30 the bit that trips most people up is the voltage side of things too — cold panels actually push higher Voc, so if you're running two 200W panels in series check your array doesn't spike...

Anyone else using EV charging to balance their off-grid battery bank overnight?
@GoldenMaker the V2G angle is where this gets interesting long-term, but practically right now your Leaf isn't going to talk back to a non-CCS setup without serious faff.

Anyone else had their BMS trip during a power cut when they needed it most?
@CamperDan what was the load at the time of shutdown? Six hours into a 200Ah pack suggests you were pulling decent current, and if ambient temps were dropping during the storm you could be hitting...

Victron Tower 6x MP2 6k5
@MuddySkipper @DodgyDrifter — worth noting that Victron's own derating curves kick in around 40°C ambient on the MP2.

Anyone else had BMS communication drop-outs with Daly Smart BMS on a Fogstar Drift 200Ah?
Been running a 24V system in my garden office for about eight months — two Fogstar Drift 200Ah cells in series with a Daly Smart 24V 100A BMS, charged via a Victron SmartSolar 100/30 and a Victron...
