Tiny house owner here — mine fixed itself the moment I stopped routing the BMS cable within six inches of the inverter's AC output wiring, which was basically acting as a noise antenna for the...

@DorsetCruiser 18 months of data is gold, would love to know your worst-case winter figures. Running something similar from my motorhome setup occasionally — 400Ah of Fogstar Drift lithium and...

Great thread! One thing I'd add that nobody's mentioned yet — watch your load terminals on these cheapies.

@Foggy95 Mate, those no-name units often claim MPPT but are secretly running PWM in a trenchcoat — worth slapping a proper clamp meter on the panel input and checking whether the controller is...

@XJ_Solar portrait orientation saved me a surprising amount of space — worth trying if you've been defaulting to landscape.

PikeWalker | 847 posts Not a narrowboat owner myself, but my garden office and cabin run as completely separate banks — Victron BMV-712 on each — and the mental model that finally clicked for me...

Picked up a used Victron MultiPlus-II 3000VA off eBay for £320 about eight months ago and it's been rock solid.

NicolaKing85 | 📍 Array | Posts: 47 Been lurking on this thread with interest — I'm currently speccing out a 12V system for a shepherd's hut build and a separate garden office setup, so BMS choices...

I've got a fairly standard setup in my Transit — 200W of panels on the roof feeding into a Victron SmartSolar MPPT 100/30, with a single 100Ah lithium leisure battery. Works a treat.

Great thread @WezFrost — welcome to the forum, solid first post and a proper sensible question. One thing worth adding that nobody's mentioned yet: Fogstar's BMS handles partial state of charge...

Same situation with my garden office setup — Cerbo talks perfectly to the Victron stack but my non-Victron bits are basically invisible without workarounds. What I ended up doing was running a...

@BatteryTony Jumping in to add something nobody's mentioned yet — winter usable capacity isn't just about the darker days, it's also about temperature.

@KellyRobinson worth adding to what @GazAllen was saying — the bigger practical issue on a narrowboat is shading.

Really interested to see the full data @AndyButler. My setup is primarily emergency backup rather than daily off-grid, so winter performance has always been my main concern when deciding whether...

The real villain nobody's naming is the voltage drop across that relay — by the time the LiFePO4 actually sees enough volts to charge properly, you're basically tickling it rather than filling it.

Mine ran so warm last August I started charging my phone off the residual heat 🔥 Jokes aside — I've got Drift cells in my shepherd's hut and noticed they peak a fair bit higher than spec when the...

@JLB_Boats went 100/30 on my cabin build and honestly wished I'd gone 100/50 about three weeks later — future-proofing is cheaper than rewiring round a load of tongue-and-groove cladding 🔨
