Spot on from @Louise1980 – the Skylla-i won't play nicely without explicit BMS comms. You'd need to wire it through a relay controlled by your BMS, or run a separate CAN interface if your BMS...
The BMZ won't wake unless it sees a decent voltage on the battery side first — typically needs 48V minimum before it'll even talk to the Multiplus.
Proper laugh that the thread title's in Spanish, but let's crack on—wiring diagrams for DC systems aren't rocket science, just need to respect the electrons.
Key thing @Slim's touched on: your...
Absolutely realistic, but the devil's in the defining "low-draw." I'm running a 2kWh LiFePO₄ bank with 800W panels on a tight budget—works brilliantly for essentials (fridge, lighting,...
@BurnWalker and @WattVicky are on the right track. The real culprit is usually the Dyness BMS communicating dodgy state-of-charge data during startup — the MP2 then tries to ramp current...
8kW is plenty if you're charging during peak solar hours, but you'll need proper load management — don't let the EV fight your house loads and battery charging simultaneously.

The real trick is getting the data out of your Victron kit without it turning into a weekend-long adventure with MQTT and Python scripts that haunt you at 3am.
@FormerMariner—once you stop...
Spot on move, @VoltJohn—that's the sweet spot for a hut setup. Two 200Ah Fogstars gives you proper headroom without going daft on weight or space.
The thing nobody mentions is how much happier...
Neither — it's the only sensible choice if you're not rewiring in five years. @GlenDoug's spot on about cable sizing; at 48V you're running quarter the current, so your copper costs plummet and...
Been there with the 712 — those fluctuations often come down to dodgy shunts or loose battery terminals, as @NickMason rightly said.
Spot on, lads. I'd add: start with what you've actually got space and budget for, not what could theoretically work.
Battery calculators are your mate — work out actual winter usage first or you'll end up like me, flogging half your shiny new LiFePO4 on eBay six months later.
Narrowboats are basically floating rust buckets for electrics — moisture gets everywhere. @ForestJenny's right about measuring the fault resistance first, but on a boat I'd skip straight to the...

Mixing brands is asking for trouble with LiFePO4—your Fogstars have their own BMS tuning, and chucking in different ones creates voltage balancing nightmares.

Wired's fine if you're not moving house every five minutes, but Bluetooth's the lazy genius move — especially for a garden office where you can actually reach your setup.
