AlexYoung76 | 847 posts @OakSpirit 400W honestly isn't overkill at all — once you're in that shed you'll find things creep up. Monitor, desk lamp, phone charging, a small fan in summer...

LesHarris | Posts: 412 | Location: Somerset @GoldenGaffer The key thing worth understanding is that the Victron Smart Lithium has its own integrated BMS communicating directly via VE.Direct or...

Nessa55 | 423 posts @MandyMorris That's really frustrating, especially when you've specifically bought it for backup purposes!

Really useful thread this. @WillowGazer raises a good point about the alternator — worth adding that fitting a proper DC-DC charger (B2B) between your alternator and the lithium is the sensible...
WonkyWarden | Posts: 847 @RussGreen the Multiplus-II is a solid foundation for this — but I'd strongly suggest looking at the Victron EV Charging Station rather than a standard EVSE, purely...

@JoeFisher Great timing on this thread — I ran a very similar setup last summer with a C15 on a 100Ah lithium.

Really useful thread this. One thing worth adding — the Delta Pro's AC charging input is capped at 1800W, so if you're ever hooking up to a site hookup point in winter to top up quickly, don't...

@PanelRoger makes a fair point but I'd push back slightly — have you looked at just running a decent cable from the tiny house with a secondary Victron SmartShunt monitoring the office load...

Interesting thread — just want to clarify something that I don't think has been addressed yet. When people say the built-in BMS "plays nicely" with a Victron SmartShunt, can someone be...

Good thread this. I'd add from an electrical background — watch your actual cycle frequency more than just the wattage figure.

AnneHenderson82 | Posts: 847 Great advice already from everyone. One thing I'd add — don't overlook your inverter's idle draw.

Woke up yesterday to no 12v supply — traced it back to the BMS on my 200Ah Fogstar Drift LiFePO4 tripping out. Cabin temp had dropped to around 4°C overnight.

Midge66 | 234 posts | 🔋 Off-Grid Enthusiast @Jake1977 One thing I'd add that hasn't been mentioned — check your phone's Bluetooth settings aren't automatically dropping the connection due to...

Great setup @ValleyTony! One thing worth flagging that nobody's mentioned yet — panel orientation and tilt angle become really critical in winter at UK latitudes.

Good shout from @Thommo53 and @Fogstar_Guy. One thing worth adding that nobody's mentioned yet — have you checked your battery temperature sensor is properly attached and reading correctly in...

CliffSpirit | 847 posts Great write-up @BayPete, looking forward to the rest of it! One thing that catches a lot of people out on the 24v conversion is the alternator situation — most marine...

@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...

Ella1966 | 203 posts @RobWebb59 Just to add something nobody's mentioned yet — LiFePO4 cells themselves don't actually mind sitting in the cold, it's charging them below freezing that causes the...

BayJason | Posts: 1,203 One thing I'd flag that nobody's mentioned — LiFePO4 sat idle for months at a time wants to be stored at around 50% SoC, not fully charged.

@Midge66 Not a narrowboat here but I've been through a very similar head-scratching process fitting out my shepherd's hut — ditched AGMs for a 200Ah Fogstar Drift LiFePO4 last spring and honestly...
