@OllieThompson73 same story here — grabbed my last batch of 280Ah cells literally within an hour of a restock notification.

FZO_Marine | 312 posts | ⚓ Liveaboard & Off-Grid @WattRoger good timing on this thread — BSS and lithium is still a bit of a grey area that catches people out.

Jumping in here as I've been running almost exactly this setup for about eight months now. What I ended up doing was using a separate Raspberry Pi Zero 2W sat alongside the Cerbo purely to handle...

CotswoldVanLifer | 312 posts @CrafterDream I'm running Drift cells in my van build rather than a home backup, but same cells so hopefully useful — I went with a JK BMS as @KangooBuild mentioned,...

Picked up a 100A Daly BMS late last year for my 280Ah LiFePO4 build in the van. All seemed fine through autumn but now we're hitting proper cold nights (we're talking 2–4°C inside the van in the...

@PV_Fan tried something similar at my place last summer. Theoretically fine, practically a nightmare unless you've got really consistent sun. Problem is your Multiplus-II is inverting to run that...

Yeah, the relay issue is real. Had the same setup in my static before I knew better — relay just sees "voltage high enough, connect" and your LiFePO4 just sits there half-charged...

Thinking of keeping my narrowboat on the cut through winter this year rather than laying her up, and I'm trying to work out if my current solar setup is actually going to cut it for keeping a 12v...

I've had a single 200W mono panel on the roof of my narrowboat since last March and through summer it was brilliant — regularly hitting 150W+ on a clear day and keeping my 100Ah lithium topped up...

Great thread @HarryMorgan. Just to add to what @Curly66 was getting at — the key thing people often miss is that G98 applies to single-phase systems under 3.68kW export, which most domestic setups...

Brummie86 | 234 posts Same setup in my Transit, pretty much. Had both running for a while thinking it was "belt and braces" but the relay was actually confusing things — kept getting...

@GafferTapeKing19 even if you somehow survive the clouds and the startup surge, your Victron MPPT will just throttle output when panels can't keep up — fridge logic goes haywire and you'll be...

@MarineClad worth checking whether your BMS has a low-temperature cutoff that might be triggering earlier than expected — some units are set quite conservatively around 5°C and will throttle...

Great points all round here. One thing worth adding — have you lot looked into insulating the battery enclosure itself?

WattJane | Posts: 847 @KangooBuild nice build! The 100/50 will be leaving charge on the table if you've got panels to spare — it's capped at 50A charge current which on a 48V bank gives you...

@JakeHall76 that's a decent little setup. The Squirrel is a solid choice — I've got a similar situation on the narrowboat, and the thing nobody tells you is how much the wood burner fights your...

SomersetCamper | 312 posts @VickyWard great timing on this thread! I've been running a Drift 100Ah in my van for about eight months and just added a second for the boat last spring, so I can speak...

Good catch from @GeorgeShaw and @Trigger on the termination — that one burned me for a solid week on my cabin build before I spotted it. One thing worth adding: check your ESS Assistant version on...

Really interested to see this thread - I've been running almost exactly this setup for about eight months now and recently added InfluxDB and Grafana into the mix alongside Node-RED, which has...
