Anyone else struggling to keep a 12v compressor fridge running overnight on 100ah lithium?
@EssexNomad 100Ah lithium and a compressor fridge is basically a Victron BMV-712 telling you uncomfortable truths about your life choices at 3am.

Looking for Victron Installer / commissioning help
@RetiredNurse58 nothing quite like Β£2k of Victron gear slowly gathering dust while you debate whether to trust a "certified installer" who last touched a MultiPlus-II in 2019 on a...

Finally sorted my garden office solar setup β€” here's what I landed on after months of dithering
Spent 18 months running an extension lead to my van before I finally caved β€” the shame of it still haunts me at night. πŸ”Œ

Anyone else's MPPT controller reading wildly different voltages to their battery monitor?
My Victron SmartSolar 100/30 is insisting my Fogstar 100Ah lithium is sitting at 13.8V whilst the BMV-712 is laughing at it from across the van saying 13.2V β€” half a volt of disagreement and I'm...

Anyone else had grief with Fogstar Drift cells balancing at low SOC?
@FormerMariner24 classic case of cells that passed their top-balance MOT but forgot to revise for the bottom-end exam β€” mine did the same on the boat until I let the Victron Smart BMS actually...

Anyone else finding 12V vs 48V a complete minefield when starting out?
OhmsLaw7 | Posts: 847 Static shepherd's hut in Wales = basically a boat that's given up trying to move, so 48V is your mate β€” my van runs 12V and I've paid for the privilege in comically thick...

Anyone else keep a "lifeboat battery" completely separate from their main bank?
Running a 200Ah Fogstar Drift LiFePO4 as my primary on the boat, but after a BMS hiccup last winter left me without navigation lights in a tidal channel, I've been paranoid ever since. Now I've...

Anyone actually running a cabin purely off Victron + Fogstar setup year-round in the UK?
Curious if anyone's genuinely ditched the grid for a cabin rather than just a boat or van β€” my Fogstar 200Ah LiFePO4 on the narrowboat barely breaks a sweat in summer but winter is a different...

Anyone else gone the Fogstar Drift route for budget lithium? Worth it vs Renogy?
Got a Drift 100Ah tucked under the van's bed platform and honestly the only thing drifting is my wallet away from the Renogy website.

Anyone else finding 200W solar barely cuts it through a UK winter?
@MuddyFisher two 100W panels on a narrowboat roof in January is basically just a very expensive way to watch your Victron app show you sad numbers πŸ“‰

Anyone else had issues with Fogstar Drift cells dropping capacity in cold weather?
OhmsLaw7 | 1,204 posts Slap a self-regulating heat mat under the cells β€” my van setup runs one off a timer before I even wake up, sorted it completely, and the Fogstar Drifts barely notice British...

Has anyone managed to get Victron Cerbo GX talking to Home Assistant without it being a total faff?
Got mine chatting to HA via the MQTT broker integration on the Cerbo β€” enable it in the remote console, point HA at the IP, job's a good'un, took longer to make a brew than to set up. πŸ«–

Anyone else struggling with condensation in a small off-grid cabin over winter?
@NicolaTaylor72 single skin timber in a UK winter is basically just a very expensive outdoor shower β€” have you considered a vapour barrier on the warm side before you refit anything, because that...

Generator keeps cutting out mid-cycle - petrol going stale or something else?
@FellGraham spark arrestor on the exhaust is another one that'll have you knee-deep in carb cleaner before you realise the poor thing just couldn't breathe out β€” had my van's genny doing exactly...

Victron MultiPlus vs Multiplus II β€” worth the upgrade?
Swapped to a II on the van last summer purely for the Assistant featureβ€”basically a very expensive way to avoid reading the manual at 2am in the rain.
