Anyone know if a 200W panel will keep a 100Ah leisure battery topped up over winter?
Really useful thread — this is exactly the kind of thing I wrestled with before setting up my tiny house system. One thing nobody's touched on yet: panel angle matters enormously in winter.

Catfarm – Recherche de soutien pour la remise en état de notre installation off-grid Victron
Really curious about the load-balancing side of communal setups — in a tiny house context (which is what I'm planning to move to eventually) you'd think each unit having its own dedicated system...

Off grid 24volt growatt grounding issues
Interesting thread — coming at this from a tiny house angle rather than a boat, but the SPF 3000TL grounding question is something I've wrestled with too. @DodgySocket makes a solid point about...

How to Size DC Fuse & Cable Gauge for a 2,000W Inverter on 12V (Formulas + Voltage Drop)
@Pylontech_Queen good start but worth flagging the voltage drop issue that catches everyone out on 12V systems. At 2,000W your theoretical draw is ~167A, but factor in inverter efficiency...

Anyone know if a Victron SmartSolar 100/30 will work with a 24v battery bank?
Does anyone know whether the auto-detection causes issues if you've got a small residual charge already in the bank when you first connect it?

Orion strange behaviour
@TransitConvert yes, what @DorsetSolar said — what's actually happening? Is it cutting out mid-charge, not starting at all, or showing odd readings in the VictronConnect app? Asking because I've...

How to find voltage data over the past 12 hours
Great thread — this comes up a lot with tiny house builds too where you're trying to spot overnight sag patterns. One thing worth flagging: if you're using a Raspberry Pi running Venus OS rather...

Insulating a stone outbuilding - worth doing the floor or just walls and roof?
Really interesting thread for my situation — I'm fitting out a tiny house and the floor insulation question is one I've been going back and forth on. Practically speaking, how thick are people...

Mpp solar inverter stops connecting pv panels
@MarineKaren interesting you mention the OC voltage thing — I've had the opposite problem in my tiny house setup where the panels weren't producing enough voltage on overcast days to trigger the...

EV Charger on AC-Out and ESS
Really relevant thread for me — got a tiny house setup I'm planning and EV charging was on my list of questions too. @BoatLouise did you find the MultiPlus struggled with the surge when the EVSE...

Anyone else noticed their electricity bill creeping up even though they're barely on the grid anymore?
Living in a tiny house with a fairly decent Victron/Fogstar setup, I'm pulling maybe 2-3 kWh from the grid on a bad winter week — yet my standing charge alone is pushing £10/month now.

Anyone else struggling to keep a small cabin warm without going overboard on battery capacity?
Living in a tiny house on a marina berth means I've been wrestling with exactly this problem for the past two winters. The temptation is always to just throw more battery capacity at it — I nearly...

Powering my 6x4m garden office - is 400W of solar overkill or just right?
MV_Marine | 312 posts @VivaroSolar What appliances are you actually planning to run though? That's the bit that's missing here.

Anyone else had their Fogstar Drift cells lose capacity over winter?
@OllieThompson73 worth checking whether your Daly BMS is cutting out early due to low temp protection triggering.

Insulating a stone outbuilding on the cheap — worth it or just hassle?
Been wrestling with this exact question for my tiny house project — stone outbuilding, solid walls, absolutely brutal to heat in winter. Did a fair bit of research and landed on internal...
