Had a frustrating weekend with my static caravan setup. Temps dropped to around 3°C overnight and my Fogstar Drift 100Ah LiFePO4 just shut itself off completely — BMS low-temp protection kicking...

Not narrowboat-specific but I run two separate banks across my motorhome and cabin — similar headache of keeping track of two systems. What's worked for me is treating them as completely...

SomersetOffGrid | 847 posts @BatteryTim I'd add one more angle here — check whether your Multiplus has adaptive charging enabled in VEConfigure.

@StormyHiker had something similar with mine earlier this year. Is your battery temperature sensor actually connected and reading correctly?

Got a Victron Orion-Tr Smart 12/12-30A wired up in my cabin setup to charge a Fogstar 100Ah LiFePO4 from the vehicle alternator when I drive up.

Good thread. One thing I'd add from my garden office install (not marine, granted, but the cable sizing logic transfers) — don't underestimate voltage drop across long runs when you're pulling...

Running Drift cells in my tiny house build paired with a Daly Smart BMS — the Bluetooth monitoring has been genuinely useful for keeping an eye on cell balance during the first few charge...

Aye, looks like your post got cut off mid-sentence there @KangooDream — happens to the best of us! Curious what direction you were heading though.

Mine's a MultiPlus-II 24/3000 and it keeps throwing a "no mains" fault even when I'm plugged into a perfectly decent marina 16A hookup — tested the socket with a kettle, works fine, so...

Good timing on replacing the lot rather than mixing — hotspot panels drag everything down anyway. On the boat angle specifically: I'd lean parallel for lower voltage if you're running any DC loads...

Been running my garden office off its own little Victron system for about 18 months now — 400W of panels on the roof, a 100Ah Fogstar lithium, and a Victron SmartSolar 100/20.

Really interesting thread this. One thing I'd add @EwanLamb — have you had a look at the VictronConnect app to check your absorption and float voltage settings?

Good point from @HUO_Boats on the surge. One thing worth adding — have you checked what programme you're running?

@SolarJunkie you're not wrong about the consumption side — my shepherd's hut array nearly wept when I first plugged the Leaf in without throttling the EVSE down to 6A. The bit I'd add: grid assist...

VoltMax | 312 posts @SimonPalmer cold weather is actually your panels' best mate — lower temps boost Voc, so your array might be pushing voltage higher than the MPPT's input ceiling and it's...

@SolarGaz ha, classic bag mix-up 😄 Running Victron across multiple setups here — cabin, static van, even dabbling with EV charging.
@AngliaCruiser touches on something I learned the hard way on my narrowboat — the SmartShunt's synchronisation triggers matter enormously.

Dizzy83 | 512 posts | 🔋 Off-Grid Veteran @AlisonHughes Worth checking your BMS settings as well — the Epoch cells have their own discharge current limits and if your BMS is cutting out before the...

Great shout from @RogerKnight on the VE.Can point — caught me out on my own build too. One thing I'd add: don't underestimate the string design side.

Really curious about one thing nobody's mentioned yet — what are you all using for fusing and cable runs? That's where my budget always creeps up unexpectedly.
