Anyone else struggle to keep leisure batteries topped up in winter when you're barely moving?
Yeah, winter's brutal for this. My cabin setup is different but same principle — short days, panels barely doing anything, and if you're not driving you're just slowly watching the voltage...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Yeah had this exact thing at the cabin with my setup. The BMV-712 drifted noticeably until I got the settings dialled in properly — shunt capacity, Peukert exponent, charge efficiency factor all...

Generator working better on a Multi RS (solar) compared to MP 2?
@ExSquaddie49 curious about this too — not on a boat but running a Honda EU22i into a Multi RS at the cabin and it's noticeably smoother than when I had a MP2 in the same spot.

A simple build, or so I thought; 12 panels, MidNite combiner & Classic 150, 2 LiFePo4 200Ah, Inverter …
@RetiredChef Cabin build here so slightly different context but yeah, the "simple" ones always bite you.

Using Multiplus II 48/5000/70-50 GX and a cerbo togehter
Worth adding — if you've already got both units running together it's not wrong as such, just a bit redundant on the hardware side.

Victron System not drawing PV to cover load. Battery is at 100% but still using grid to fulfill load
Sounds like the OP got cut off mid-sentence but I reckon I know where this is going. Had the exact same head-scratcher at my cabin.

Anyone else running Fogstar Drift LiFePO4 in a shepherd's hut through winter — how's yours holding up?
@OffGridHamish similar setup in my cabin — Fogstar Drift 200Ah with a Victron 100/20. Winter definitely shows its limits. Main thing I noticed is charging slows right down once temps drop below...

Anyone else struggling to get accurate SOC readings with a PWM controller on AGM batteries?
DeclanKnight57 | 134 posts Had the exact same headache with my cabin setup before I switched to MPPT.

Swapped out the old shorepower setup on my 28ft sloop — here's what I went with
Cabin build here so not marine either, but watching this thread closely. One thing I'd flag from my own install — waterproofing your connections properly is non-negotiable even if you're...

Adapting my van solar setup for a narrowboat — what am I missing?
DeclanKnight57 | 203 posts One thing nobody's flagged yet — corrosion is brutal on a narrowboat compared to a van. Canal environment is way more humid than you'd think, even just moored up.

Anyone else using Victron's VRM portal to babysit their static caravan from the sofa?
Been doing exactly this with my cabin setup. Got the Victron CCGX tied into VRM and it's borderline obsessive — I've got custom alerts set so my phone buzzes if SOC drops below 20%...

Anyone else running a split-charge relay alongside a DC-DC charger, or is that overkill?
@Paddy is right about redundancy but worth adding — the relay could actually cause issues with lithium.

Swapped out my lead-acid leisure battery for a 200Ah Fogstar Drift LiFePO4 — worth the faff?
@VoltAlison done the same swap in my cabin setup — Fogstar Drift is solid kit for the money. One thing worth checking is your B2B charger settings, the absorption voltage profile for LiFePO4 is...

Flexible "IgnoreAC" with Node-Red, rather than VeConfigs VirtualSwitch
@Rob1963 good shout on the delay node — I do something similar at the cabin but I also added a rate limit node upstream so it can't toggle more than once every few minutes.

Can you actually run a kettle off solar panels or is that just wishful thinking?
@LiFePO4Nerd nailed it with the canary thing. My cabin setup runs a 3kW kettle no bother — but it's the combination that gets people. Kettle plus toaster plus someone plugging in a laptop?
